Effect of testosterone therapy on breast tissue composition and mammographic breast density in trans masculine individuals. Breast Cancer Res 2024; 26:109. [PMID: 38956693 PMCID: PMC11221014 DOI: 10.1186/s13058-024-01867-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2024] [Accepted: 06/27/2024] [Indexed: 07/04/2024] Open
Abstract
BACKGROUND The effect of gender-affirming testosterone therapy (TT) on breast cancer risk is unclear. This study investigated the association between TT and breast tissue composition and breast tissue density in trans masculine individuals (TMIs). METHODS Of the 444 TMIs who underwent chest-contouring surgeries between 2013 and 2019, breast tissue composition was assessed in 425 TMIs by the pathologists (categories of lobular atrophy and stromal composition) and using our automated deep-learning algorithm (% epithelium, % fibrous stroma, and % fat). Forty-two out of 444 TMIs had mammography prior to surgery and their breast tissue density was read by a radiologist. Mammography digital files, available for 25/42 TMIs, were analyzed using the LIBRA software to obtain percent density, absolute dense area, and absolute non-dense area. Linear regression was used to describe the associations between duration of TT use and breast tissue composition or breast tissue density measures, while adjusting for potential confounders. Analyses stratified by body mass index were also conducted. RESULTS Longer duration of TT use was associated with increasing degrees of lobular atrophy (p < 0.001) but not fibrous content (p = 0.82). Every 6 months of TT was associated with decreasing amounts of epithelium (exp(β) = 0.97, 95% CI 0.95,0.98, adj p = 0.005) and fibrous stroma (exp(β) = 0.99, 95% CI 0.98,1.00, adj p = 0.05), but not fat (exp(β) = 1.01, 95%CI 0.98,1.05, adj p = 0.39). The effect of TT on breast epithelium was attenuated in overweight/obese TMIs (exp(β) = 0.98, 95% CI 0.95,1.01, adj p = 0.14). When comparing TT users versus non-users, TT users had 28% less epithelium (exp(β) = 0.72, 95% CI 0.58,0.90, adj p = 0.003). There was no association between TT and radiologist's breast density assessment (p = 0.58) or LIBRA measurements (p > 0.05). CONCLUSIONS TT decreases breast epithelium, but this effect is attenuated in overweight/obese TMIs. TT has the potential to affect the breast cancer risk of TMIs. Further studies are warranted to elucidate the effect of TT on breast density and breast cancer risk.

Abstract
BACKGROUND The risk of breast cancer in trans men is currently a poorly understood subject and trans men likely carries a different level of risk from that of cis women. AIM This review aims to review several aspects that affects breast cancer risk in trans men and to apply the Swiss cheese model to highlight these risks. The study takes its cue from a systematic review of all described breast cancer cases in trans men following medical or surgical intervention because of gender dysphoria. METHODS PubMed was systematically searched on the 14th of March 2023 to find all published cases of breast cancer following chest contouring surgery in trans men. Included articles had to involve trans men, the diagnosis of breast cancer had to be preceded by either a medical or surgical intervention related to gender dysphoria, and cases needed to involve invasive breast cancer or ductal carcinoma in situ. Articles were excluded if gender identity in the case subject was unclear and/or a full English version of the report was unavailable. Quality and risk of bias was evaluated using the GRADE protocol. A literature review of specific risk altering aspects in this population followed. The Swiss cheese model was employed to present a risk analysis and to propose ways of managing this risk. RESULTS 28 cases of breast cancer in trans men have been published. The Swiss cheese model identified several weaknesses associated with methods of preventing breast cancer in trans men. CLINICAL IMPLICATIONS This study may highlight the difficulties with managing risk factors concerning breast cancer in trans men to clinicians not encountering this patient group frequently. CONCLUSION This review finds that evidence for most aspects concerning breast cancer in trans men are inadequate, which supports the establishment of a risk-management approach to breast cancer in trans men.

Abstract
The pathological assessment of a breast surgical specimen starts with macroscopic evaluation, arguably one of the most critical steps, as only a small percentage of the tissue is examined microscopically. To properly evaluate and select tissue sections from breast specimens, it is essential to correlate radiological findings, prior biopsies, procedures and treatment with the gross findings. Owing to its fatty nature, breast tissue requires special attention for proper fixation to ensure appropriate microscopic evaluation and performance of ancillary studies. In addition, knowledge of the information necessary for patient management will ensure that these data are collected during the macroscopic evaluation, and appropriate sections are taken to obtain the information needed from the microscopic evaluation. Herein, we present a review of the macroscopic evaluation of different breast specimen types, including processing requirements, challenges and recommendations.

Abstract
Objective Determine the association between TT and breast tissue composition and breast tissue density in trans masculine individuals (TMIs). Design This is a cross-sectional study. Setting TMIs (n=444) underwent chest-contouring surgeries to treat their gender dysphoria between 2013 and 2019 at an urban medical center. Participants Of the 444 TMIs, 425 had pathology images analyzed by our deep-learning algorithm to extract breast tissue composition. A subset of 42/444 TMIs had mammography prior to surgery; mammography files were available for 25/42 TMIs and analyzed using a breast density software, LIBRA. Main Outcomes and Measures The first outcome was the association of duration of TT and breast tissue composition assessed by pathologists (categories of lobular atrophy and stromal composition) or by our algorithm (% epithelium, % fibrous stroma, and % fat). The second outcome is the association of TT and breast density as assessed by a radiologist (categorical variable) or by LIBRA (percent density, absolute dense area, and absolute non-dense area). Results Length of TT was associated with increasing degrees of lobular atrophy ( p <0.001) but not fibrous content ( p =0.821) when assessed by the pathologists. Every six months of TT was associated with decreased amounts of both epithelium (exp(β)=0.97, 95% CI 0.95-0.98, adj p =0.005) and stroma (exp(β)=0.99, 95% CI 0.98-1.00, adj p =0.051), but not fat (exp(β)=1.01, 95%CI 0.98-1.05, p =0.394) in fully adjusted models. There was no association between TT and radiologist's breast density assessment ( p =0.575) or LIBRA measurements ( p >0.05). Conclusions TT decreases breast epithelium and fibrous stroma, thus potentially reducing the breast cancer risk of TMIs. Further studies are warranted to elucidate the effect of TT on breast density and breast cancer risk. Summary Box Very little is known about the effect of gender-affirming testosterone therapy on cancer risks, such as breast cancer.Epidemiological studies had different conclusions about the association between testosterone and breast cancer in cisgender women (positive association) and trans masculine individuals (inverse association).More laboratory-based research are needed to understand the effect of testosterone on breast cancer risk in the understudied trans masculine population.Our study provides quantitative histological evidence to support prior epidemiological reports that testosterone may reduce breast cancer risk in trans masculine individuals.

Masculinizing hormone therapy effect on breast tissue: Changes in estrogen and androgen receptors in transgender female-to-male mastectomies. Breast 2023; 72:103596. [PMID: 37951051 PMCID: PMC10665694 DOI: 10.1016/j.breast.2023.103596] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 10/03/2023] [Accepted: 10/26/2023] [Indexed: 11/13/2023] Open
Abstract
PURPOSE Almost two percent of individuals in the United States identify as gender non-conforming. In the female-to-male (FTM) transgender population, masculinizing hormone therapy with testosterone is commonly prescribed in gender transition. To date, the effects of exogenous androgens on breast tissue and its roles in altering breast cancer risk are poorly understood. This study examines the histopathologic findings in gender affirming mastectomy (GAM) in transgender FTM patients and the effects of exogenous androgens on estrogen receptors (ER) and androgen receptors (AR). METHODS A retrospective review of pathology specimens obtained between 2017 and 2020 was performed comparing androgen exposed breast tissue with breast tissue without androgen exposure. Breast specimens were obtained from patients who underwent FTM GAM with recorded exogenous androgen exposure. Control breast specimens were obtained from reduction mammoplasty (RM) procedures in cisgender women which were aged matched to the GAM cohort, as well as postmenopausal women with benign/prophylactic mastectomy procedures; all controls were without androgen exposure. The histopathologic findings were assessed. Immunohistochemistry for AR and ER was performed and the score interpreted by digital image analysis. RESULTS Androgen-exposed breast tissue revealed dense fibrotic stroma, lobular atrophy, thickened lobular basement membranes, and gynecomastoid changes. Longer duration of androgen exposure resulted in a more pronounced effect. The incidence of atypia or cancer was lower in GAM than RM cohort. ER and AR expression was highest in transgender male breast tissue with intermediate duration of exogenous androgen exposure. CONCLUSION Increased androgen exposure is associated with lobular atrophy and gynecomastoid changes in breast parenchyma. Overall, ER and AR are expressed strongly in lobular epithelium in patients with prolonged androgen exposure. Exogenous testosterone does not appear to increase risk for breast cancer. Additional studies are needed to investigate the mechanism responsible for these changes at a cellular level and its role in cancer development.

Abstract
BACKGROUND Chest contouring is the most common surgical procedure transmen receive. Only a few articles discuss the importance of preoperative imaging and postoperative histopathological analysis of excised breast tissue. We studied the findings of preoperative breast imaging and the results of postoperative histopathological analysis in a clinical setting. MATERIALS AND METHODS Data from 220 patients were collected retrospectively from 2005 to 2018. Preoperative imaging modalities and their findings were recorded and classified according to the American College of Radiology Breast Imaging Reporting and Data System. The histopathological findings in breast specimens were categorized based on the World Health Organization Classification of Breast Tumors (5th edition). RESULTS Preoperative imaging was performed in 133 (60.5%) patients. Patients in the ultrasound-only group were younger (mean age 22.8) than the other groups (mammogram (MGR) 37 years and MGR+US 35.5 years). Preoperative imaging results were normal in 131 (98.5%) patients. Two patients needed further evaluation. Histopathological results were available on 206 (93.6%) patients. The most common histopathological findings were fibrosis (67.5%), atrophy (34.3%), and chronic mastopathy (14.5%). There were no high-risk or malignant findings. CONCLUSIONS The need for further examinations based on routine preoperative imaging was low (1.5%). Therefore, more individualized patient selection for preoperative imaging is justified. There were no high-risk or malignant findings in histopathological analysis, and the occurrence of benign findings was similar to that reported in previous studies. Despite our findings, based on current knowledge, histopathological examination of excised breast tissue can still be recommended. Therefore, future studies are needed to define clear guidelines.

Abstract
BACKGROUND Adolescent and young adult cancer patients (AYAs) who are sexual and gender minorities (SGM) are a rapidly increasing population that experiences unmet cancer-related needs. Despite emerging awareness, little is known about cancer care and outcomes for this vulnerable population. The purpose of this scoping review was to explore current knowledge and gaps in the literature on cancer care and outcomes for AYAs who identify as SGM. METHODS We reviewed empirical knowledge on SGM AYAs by identifying, describing, and critically appraising the literature to date. We conducted a comprehensive search on OVID MEDLINE, PsycINFO, and CINAHL in February 2022. Additionally, we developed and piloted a conceptual framework for appraising SGM AYA research. RESULTS A total of 37 articles were included in the final review. Most studies focused exclusively on SGM-related outcomes as the primary aim of the study (81.1%, n = 30), whereas others included some focus on SGM-related outcomes (18.9%, n = 7). The majority of studies included AYAs as part of a broader age range (86.0%, n = 32), and only a few studies examined exclusively AYA samples (14.0%, n = 5). Gaps in scientific evidence on SGM AYAs were seen across the cancer care continuum. CONCLUSION Numerous gaps in knowledge of cancer care and outcomes exist for SGM AYAs diagnosed with cancer. Future efforts should fill this void with high-quality empirical studies that reveal unknown disparities in care and outcomes and are inclusive of the intersectionality of SGM AYAs with other minoritized experiences, thereby advancing health equity in meaningful ways.

Abstract
BACKGROUND Exogenous testosterone is vital to gender-affirming therapy for transmasculine individuals. Testosterone may be implicated in breast cancer (BCa) because it can activate androgen and estrogen receptors. To further explore this risk, we performed a systematic review to investigate the impact of exogenous testosterone on BCa risk in transmasculine individuals. METHODS We searched PubMed/MEDLINE and Ovid/Embase for clinical and preclinical studies assessing BCa and testosterone therapy and screened 6125 articles independently. We ascertained level of evidence using a modified tool from Cook et al (Chest. 1992;102:305S-311S) and risk of bias using a modified Joanna Briggs Institute's Critical Appraisal Tool. RESULTS Seventy-six studies were included. Epidemiological data suggested that BCa incidence was higher in transmasculine individuals compared with cisgender men but lower compared with cisgender women. Histological studies of transmasculine breast tissue samples also demonstrated a low incidence of precancerous lesions. Interestingly, cases demonstrated that BCa occurred at a younger average age in transmasculine individuals and was predominantly hormone receptor positive. The mechanism for BCa in transmasculine individuals may be related to androgen receptor stimulation or conversion to estradiol. Serum studies reported varied estradiol levels associated with exogenous testosterone. Animal and in vitro studies demonstrated that testosterone was growth inhibitory but may induce proliferation at higher doses or with low estradiol levels. CONCLUSIONS Plastic surgeons play a critical role in providing gender-affirming care for transmasculine patients. The limited studies available suggest that this patient population has decreased risk for BCa when compared with cisgender women; however, any BCa that does occur may have different clinical presentations and underlying mechanisms compared with cisgender women and men. Overall, the limitations for clinical studies and discrepancies among preclinical studies warrant further investigation.

Abstract
OBJECTIVES To assess the histopathologic features of breast tissue of transgender men (TM) undergoing gender-affirming bilateral mastectomies in relation to androgen therapy (AT). METHODS We reviewed 374 transgender bilateral mastectomy cases from 2017 to 2020. Of these, 314 (84.4%) patients received preoperative AT. We compared these with 127 cases of cisgender females undergoing elective breast reduction. RESULTS Breast specimens from TM on AT, compared with cisgender women, showed a median higher gross percentage of fibrous tissue (P < .001), reduced lobular density (P = .004), higher amount of lobular atrophy (P < .001), and lower incidence of cysts (P < .001), apocrine metaplasia (P < .001), calcifications (P < .001), columnar cell change (P = .002), and atypia (P = .003). Each additional month of AT was associated with a 2% decrease in the odds of having nonapocrine cysts (P = .02), a 5% decrease in the odds of having usual ductal hyperplasia (P = .007), and a 0.14% decrease in median lobular density (95% confidence interval, -0.18 to -0.05). CONCLUSIONS In this study, breast specimens from TM, particularly with a history of AT, had a higher proportion of fibrous tissue, fewer lobules, and a higher degree of lobular atrophy than cisgender females. Rare cases of atypia were not predicted by preoperative imaging or gross findings, supporting routine microscopic evaluation of these specimens.

Abstract
BACKGROUND No guidelines exist regarding management of breast tissue for transmasculine and gender-nonconforming individuals. This study aims to investigate the experiences and practices regarding perioperative breast cancer risk management among the American Society of Plastic Surgery (ASPS) surgeons performing chest masculinization surgery. METHODS An anonymous online 19 question survey was sent to 2517 US-based ASPS members in October 2019. RESULTS A total of 69 responses were analyzed. High volume surgeons were more likely from academic centers (OR 4.88 CI 1.67 - 15.22; p=0.005). Age ≥40 (85.5%, n=59) and family history of breast cancer in first-degree relatives (68.1%, n=47) or family with a diagnosis before age 40 (71.0%, n=49) were the most common indications for preoperative imaging. 27.5% (n=19) of the respondents routinely excise all macroscopic breast tissue, with 30.4% (n=21) routinely leaving breast tissue. 73.9% (n=51) of respondents routinely send specimens to pathology. There was no significant correlation between surgical volume or type of practice and odds of sending specimens to pathology. High patient costs and patient reluctance (39.1%, n=27, and 35.3%, n=24, respectively) were the most often cited barriers for sending specimens to pathology. 8.7% (n=6) of respondents have found malignant or premalignant lesions in masculinizing breast specimens. CONCLUSION Large variation was found among surgeons' perioperative management of chest masculinizing surgery patients regarding preoperative cancer screening, pathologic assessment of resected tissue, and postoperative cancer surveillance. Standardization of care and further studies are needed to document risk, incidence, and prevalence of breast cancer in the transmasculine population before and after surgery.

Abstract
As gender-affirming surgeries become more routine, it is increasingly important for pathologists to recognize the expected histologic changes seen in various tissues secondary to gender-affirming hormone therapy. For example, exogenous testosterone-related squamous atrophy or transitional cell metaplasia of the cervix may be confused for high-grade squamous intraepithelial lesion. In addition to distinguishing between benign and dysplastic/malignant features, pathologists should be mindful of the phrasing of their reports and aim to use objective, nongendered language.

Abstract
BACKGROUND The incidence of breast cancer in transmale patients and their continued risk after gender-affirming mastectomy (GAM) has not been well established. Plastic surgeons who offer GAM are often one of the few medical professionals sought out by this population, placing them in a unique position to not only deliver surgical care but also improve access to preventative cancer care. METHODS We reviewed the senior author's experience with GAMs over the past 5 years for any incidence of breast cancer noted after or at time of surgery. We subsequently performed a thorough review of the literature for cases of breast cancer in transmen, to provide a comprehensive overview of screening, therapy, and postoperative surveillance practices. RESULTS We identified 2 cases of breast cancer (ages 49 and 54 years) found on routine examination of pathology specimens after GAM at our institution. Both patients had been taking hormone therapy for the past 1 year. Pathology specimen revealed low-grade estrogen receptor-/progesterone receptor-positive ductal carcinoma in situ in 1 patient, and estrogen receptor-/progesterone receptor-positive invasive ductal carcinoma in the other. Both patients were referred to oncology for appropriate treatment, and both elected to continue their exogenous hormone therapy for personal reasons.Review of the literature demonstrated 36 other cases of documented breast cancer in transmen. Sixty-seven percent (24) were found after GAM, and of those, 50% were incidentally found on pathology specimen. At least 50% were found to be either estrogen-, progesterone-, or androgen receptor-positive cancers. At least 17% of cases documented continued use of masculinizing hormone therapy after cancer diagnosis. CONCLUSIONS Most documented cases of breast cancer in transmen were diagnosed after gender-affirming surgery, which would suggest residual breast tissue does pose some risk for breast cancer. In addition, those diagnosed with cancer may elect to continue exogenous testosterone therapy despite potential added risks with hormone-receptor positivity. These cases highlight the need for agreement in current screening practices, surgical recommendations, and continuation of masculinizing hormone therapy.Plastic surgeons have the unique opportunity to educate these patients on appropriate breast cancer-related surveillance both before and after chest surgery.

Abstract
With the increasing practice of gender-affirming mastectomy as a therapeutic procedure in the setting of gender dysphoria, there has come a profusion of literature on the pathologic findings within these specimens. Findings reported in over 1500 patients have not included either prostatic metaplasia or pilar metaplasia of breast epithelium. We encountered both of these findings in the course of routine surgical pathology practice and therefore aimed to analyze these index cases together with a retrospective cohort to determine the prevalence, anatomic distribution, pathologic features, and associated clinical findings of prostatic metaplasia and pilar metaplasia in the setting of gender-affirming mastectomy. In addition to the 2 index cases, 20 additional archival gender-affirming mastectomy specimens were studied. Before mastectomies, all but 1 patient received testosterone cypionate, 6/22 patients received norethindrone, and 21/22 practiced breast binding. Prostatic metaplasia, characterized by glandular proliferation along the basal layer of epithelium in breast ducts, and in one case, within lobules, was seen in 18/22 specimens; 4/22 showed pilar metaplasia, consisting of hair shafts located within breast ducts, associated with squamoid metaplasia resembling hair matriceal differentiation. By immunohistochemistry, prostatic metaplasia was positive for PSA in 16/20 cases and positive for NKX3.1 in 15/20 cases. Forty-three reduction mammoplasty control cases showed no pilar metaplasia and no definite prostatic metaplasia, with no PSA and NKX3.1 staining observed. We demonstrate that prostatic metaplasia and pilar metaplasia are strikingly common findings in specimens from female-assigned-at-birth transgender patients undergoing gender-affirming mastectomy. Awareness of these novel entities in the breast is important, to distinguish them from other breast epithelial proliferations and to facilitate accrual of follow-up data for better understanding their natural history.

Abstract
Background: The rate of masculinizing chest surgery for gender affirmation continues to increase. With a paucity of literature on pathological evaluation of breast specimens in this patient population, there is a need for these data and for protocols on the handling of these specimens. Methods: A retrospective chart review was performed between 2015 and 2020 on all patients who underwent chest masculinization surgery for gender dysphoria by the senior author (J.D.K.). Inclusion criteria were any patient with sex assigned female at birth who underwent removal of breast and/or nipple areolar complex tissue for gender affirmation. Patient demographics were recorded. Bilateral breast tissue was sent for routine pathology in all cases and findings were recorded. A p-value of <0.05 was considered significant. Results: Seventy-four consecutive patients and 148 breast specimen reports were identified from a database and included in the study. The mean age was 26 years (15-49). Thirty-nine patients had a known history of chest wall binding and 60 patients had undergone preoperative androgen therapy. There was no invasive or in situ carcinoma found in any breast tissue specimens. Thirty-four patients had a benign lesion in one or both breast specimens. Atypical lobular hyperplasia was found in one patient's specimen. A history of chest wall binding was not correlated with any benign lesions (p=0.79) or stromal fibrosis (p=0.94). A history of testosterone use was not correlated with any benign lesions (p=0.35) or stromal fibrosis (p=0.20). Conclusions: The prevalence (1.4%) of significant breast pathology and of benign findings (46%) in our study closely correlates with the rates in the literature. We found no correlation between significant breast pathology or benign lesions and a history of chest wall binding or preoperative androgen therapy. We recommend all breast specimens removed during chest masculinization surgery be sent for pathological evaluation.

Abstract
CONTEXT.— Gender-affirming surgery is part of a multidisciplinary approach in gender transitioning. Deeper histologic examination may strengthen care for transmasculine individuals and increase the understanding of the influence of hormonal therapy in specific organs. OBJECTIVE.— To evaluate and catalogue histologic findings of tissue obtained from gender-affirming gynecologic surgery and cervical cytology specimens. DESIGN.— This is an institutional review board-approved retrospective study that included transmasculine individuals who underwent gender-affirming gynecologic surgery from January 2015 to June 2020. All surgical gynecologic pathology and cervical cytology slides were reviewed by 2 pathologists. RESULTS.— Fifty-five patients were included, which represented 40 uteri, 35 bilateral ovaries, 15 vaginectomy specimens, and 24 cervical cytology results. The median age was 27 years (range, 18-56) and 94% (50 of 53) of patients were receiving testosterone for at least 1 year. Seventy-five percent (30 of 40) of endometria were inactive, while 25% (10 of 40) showed evidence of cycling. Transitional cell metaplasia was the most common finding in the cervix (17 of 40) and vagina (15 of 15), reflecting a high percentage (4 of 24) of unsatisfactory or ASC-US (atypical squamous cells of undetermined significance) cervical cytologies. Prostatic-type glands were identified in 20% (8 of 40) of cervices and 67% (10 of 15) of vaginectomy specimens. Multiple bilateral cystic follicles and evidence of follicular maturation were present in 57% (20 of 35) of cases. Four cases showed paratubal epididymis-like mesonephric remnant hypertrophy. CONCLUSIONS.— A comprehensive evaluation of tissue from gender-affirming surgery increases knowledge of the changes following androgen therapy in transmasculine individuals and may contribute to optimal patient care by raising awareness of normal histologic variations in this population.

Abstract
CONTEXT.— Transgender men and transmasculine persons experience a discordance between the female sex they were assigned at birth and their gender. They may choose to take hormone therapy and/or undergo surgery to masculinize the body. Understanding the common (and less common) histologic changes present in patients taking masculinizing hormones will empower pathologists to better serve this unique patient population. OBJECTIVE.— To summarize histologic findings in surgical pathology specimens from persons taking masculinizing hormones as a part of gender transition. DATA SOURCES.— A systematic review of the OVID Medline and PubMed databases was performed to identify all studies describing histologic findings in surgical pathology specimens from transgender men from January 1946 to January 2021. CONCLUSIONS.— Publication in this area has markedly increased in the last 2 decades. However, most of the studies identified were descriptive and case reports describing changes seen in specimens removed as a part of masculinizing surgical procedures. Benign histologic findings include stromal hyalinization and epithelial atrophy in the breast, polycystic ovarian syndrome-like changes in the ovary, and transitional cell metaplasia in the cervix. The most commonly reported neoplastic finding was adenocarcinoma of the breast, with rare cases of ovarian, endometrial, cervical, vaginal, pituitary, pancreatic, and cardiovascular neoplasia also reported. Ongoing research in this area is needed to better characterize the histologic findings in persons taking masculinizing hormones to provide a deeper understanding of the effect of these treatments on different tissues and facilitate better patient management.

Abstract
BACKGROUND Gender-affirming surgery is becoming increasingly more common. Procedures including chest masculinization, breast augmentation, vaginoplasty, metoidioplasty, and phalloplasty routinely generate discarded tissue. The incidence of finding an occult malignancy or premalignant lesion in specimens from gender-affirming surgery is unknown. The authors therefore conducted a retrospective review of all transgender patients at their institution who underwent gender-affirming surgery to determine the incidence of precancerous and malignant lesions found incidentally. METHODS A retrospective review of transgender patients who underwent gender-affirming surgery at the authors' institution between 2017 and 2018 performed by a single plastic surgeon and a single reconstructive urologic surgeon was conducted. Only transgender patients who underwent gender-affirming surgery that led to routine pathologic review of discarded tissue (mastectomy, vaginoplasty, vaginectomy as part of phalloplasty) were included. Charts were reviewed and patient demographics, duration of hormonal therapy, medical comorbidities, genetic risk factors for cancer, medications (including steroids or other immunosuppressants), pathology reports, and cancer management were recorded. RESULTS Between 2017 and 2018, 295 transgender patients underwent gender-affirming surgery that generated discarded tissue sent for pathologic evaluation. During this period, 193 bilateral mastectomies, 94 vaginoplasties with orchiectomies, and eight vaginectomies were performed; 6.4 percent of all patients had an atypical lesion found on routine pathologic evaluation. CONCLUSIONS Gender-affirming surgery is increasingly more common given the increase in access to care. The authors' review of routine pathologic specimens generated from gender-affirming surgery yielded a 6.4 percent rate of finding atypical lesions requiring further evaluation. The authors advocate that all specimens be sent for pathologic evaluation.

Abstract
Testosterone therapy (TT) is administered to enhance masculinization in transgender individuals. The long-term effect of exogenous testosterone on breast tissues remains unclear. Our study evaluated the modulation of breast morphology by TT in transgender individuals with special attention to duration of TT. We reviewed 447 breast surgical specimens from gender affirming chest-contouring surgery, and compared histopathological findings including degree of lobular atrophy, and atypical and non-atypical proliferations between subjects who did (n = 367) and did not (n = 79) receive TT. TT for one patient was unknown. TT for >12 months was associated with seven histopathological features. Longer duration of TT was significantly associated with higher degrees of lobular atrophy (p < 0.001). This relationship remained significant after accounting for age at surgery, ethnicity, body mass index, and presurgical oophorectomy (adjusted p < 0.001). Four types of lesions were more likely to be absent in breast tissues exposed to longer durations of TT: cysts (median = 16.2 months; p < 0.01; adjusted p = 0.01), fibroadenoma (median = 14.8 months; p = 0.02; adjusted p = 0.07), pseudoangiomatous stromal hyperplasia (median = 17.0 months; p < 0.001; adjusted p < 0.001), and papillomas (median = 14.7 months; p = 0.04; adjusted p = 0.20). Columnar cell change and mild inflammation were also less likely to occur in subjects receiving TT (p < 0.05), but were not linked to the duration of TT. Atypia and ductal carcinoma in situ were detected in 11 subjects (2.5%) all of whom received TT ranging from 10.1 to 64.1 months. The incidental findings of high-risk lesions and carcinoma as well as the risk of cancer in residual breast tissue after chest-contouring surgery warrant the consideration of culturally sensitive routine breast cancer screening protocols for transgender men and masculine-centered gender nonconforming individuals. Long-term follow-up studies and molecular investigations are needed to understand the breast cancer risk of transgender individuals who receive TT.

Abstract
Background: Transgender individuals experience barriers to accessing healthcare including financial difficulties, lack of insurance, and discrimination and victimization by medical providers. Transmasculine patients face unique challenges and are more at risk for reproductive pathology resulting from a lack of regular gynecological care. Presently, a dearth of research exists on the needs of transmasculine patients in gynecological healthcare settings. While the literature on experiences of transmasculine individuals has focused on physical health and risk factors for this population, this study focuses on the information that transmasculine individuals want their gynecologists to know when working with trans patients. Aim: The aim of the present study was to explore the lived experiences of transmasculine individuals in order to understand what they feel their medical providers need to know about their experiences seeking gynecological care. Method: Participants included 167 adults who identified as masculine of center or trans men ranging in age from 18 - 56 (M = 27.99, SD = 6.06). Participants completed an online survey and responded to open-ended questions about their gynecological healthcare experiences. Qualitative responses were analyzed via thematic analysis. Results: Results revealed four information-salient themes, including: 1) Patient comfort levels; 2) Language; 3) Provider assumptions; and 4) Provider knowledge. Conclusions: Findings suggest that gynecologists are key in both exacerbating barriers and creating more affirming spaces for transmasculine patients. Discussion of the results focuses on the ways that providers can improve the gynecologic healthcare experiences of their transmasculine patients.
