Boyd CJ, Bekisz JM, Hemal K, Sorenson TJ, Karp NS. Differential preferences in breast aesthetics by self-identified demographics assessed on a national survey. J Plast Reconstr Aesthet Surg 2024; 90:60-66. [PMID: 38364668 DOI: 10.1016/j.bjps.2024.01.002] [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: 10/26/2023] [Revised: 12/03/2023] [Accepted: 01/29/2024] [Indexed: 02/18/2024]
Abstract
There is a paucity of literature examining how preferences differ amongst various demographic groups. This study aimed to assess how perceptions of the ideal breast differ between respondents stratified by self-identified demographic factors. A cohort of 25 patients from the senior surgeon's practice presenting for breast surgery was assembled. Pre-operative anteroposterior photographs of these patients were distributed via Qualtrics (Seattle, WA) to a large sample designed to be representative of the demographics of the United States. Survey questions aimed to measure respondents' impressions of 'breast attractiveness'. Respondents were asked to rate breasts on a Likert scale. Survey responses were analysed for differences in breast aesthetic preferences by sex, gender, sexual orientation, and race. Males rated all breasts higher on the Likert scale for attractiveness than females (2.8 vs 2.5, p < 0.001). Despite this discrepancy, ratings amongst male and female respondents were highly correlated with one another (R = 0.940; p < 0.0001). Considering sexual orientation, individuals attracted to women provided significantly higher attractiveness ratings to all breasts compared to individuals attracted to men only (2.8 vs 2.5, p < 0.001). White or Caucasian individuals ascribed significantly higher breast attractiveness ratings than Asian individuals (2.7 vs 2.2, p < 0.001), but not Black or African American individuals (2.7 vs 2.4, p = 0.23). Despite these racial discrepancies in mean breast attractiveness, ratings amongst the three groups were highly correlated. In a sample representative of the United States, a difference in breast aesthetic appraisal was observed by demographic factors. These findings merit further investigation to understand these trends and observations.

Abstract
Background A female's breasts are integrally tied to her identity and sense of femininity. Despite extensive study of breast aesthetics, there is no discrete formula for the "ideal breast" to guide the aesthetic surgeon. Racial and cultural differences heavily influence preferences in breast morphology. Artificial intelligence (AI) is ubiquitous in modern culture and may aid in further understanding ideal breast aesthetics. Objectives This study analyzed AI-generated images of aesthetically ideal breasts, evaluated for morphologic differences based on race, and compared findings to the literature. Methods An openly accessible AI image-generator platform was used to generate images of aesthetically ideal Caucasian, African American, and Asian breasts in 3-quarter profile and frontal views using simple text prompts. Breast measurements were obtained and compared between each racial cohort and to that of previously described ideal breast parameters. Results Twenty-five images were analyzed per racial cohort, per pose (150 total). Caucasian breasts were observed to fit nicely into previously described ideal breast templates. However, upper-to-lower pole ratios, nipple angles, upper pole slope contours, nipple-areolar complex positions, and areolar size were observed to have statistically significant differences between racial cohorts. Conclusions Defining the aesthetically ideal breast remains a complex and multifaceted challenge, requiring consideration of racial and cultural differences. The AI-generated breasts in this study were found to have significant differences between racial groups, support several previously described breast ideals, and provide insight into current and future ethical issues related to AI in aesthetic surgery.

Abstract
In this review, we discuss the long-known problem of tissue-specific carcinogenesis in BRCA1 and BRCA2 mutation carriers: while the genes are expressed ubiquitously, increased cancer risk is observed mostly in the breast and ovaries, and to a much lesser extent, in some other tissues such as the prostate or pancreas. We reevaluate hypotheses on the evolutionary origin of these mutations in humans. Also, we align together the reports that at least some great apes have much lower risks of epithelial cancers in general and breast cancer in particular with the fact that humans have more voluminous breast tissue as compared to their closest extant relatives, particularly chimpanzees and bonobos. We conjecture that this disparity may be a consequence of sexual selection, augmented via selection for enhanced lactation. Further, we argue that there is an organ-specific enigma similar to the Peto paradox: breast cancer risk in humans is only minimally correlated with breast size. These considerations lead to the hypothesis that, along with the evolutionary development of larger breasts in humans, additional changes have played a balancing role in suppressing breast cancer. These yet-to-be-discovered mechanisms, while purely speculative, may be valuable to understanding human breast cancer, though they may not be exclusive to the mammary gland epithelial cells. Combining these themes, we review some anti-carcinogenesis preventive strategies and prospects of new interventions against breast cancer.

Abstract
Objective We aim to clarify the vascular and nerve anatomy of the breast and combine it with an ultrasound knife to use in transaxillary endoscopic biplane breast augmentation. Methods This study is a retrospective review of patients undergoing transaxillary endoscopic biplane breast augmentation between October and October 2021. Related variables were collected using a standardized data collection template. The detailed process of the transaxillary endoscopic biplane breast augmentation under anatomy instruction is carefully described in this study, and the postoperative effect was closely observed. Results Sixty-three female patients underwent transaxillary endoscopic biplane breast augmentation. The average implants volume counted 242.46 ± 31.34 cc, and the average operation time was 155.92 ± 22.34 min. Patients were followed up for a mean of 13.67 months (range, 3-27 months), and most of the patients achieved good postoperative results and no severe complications and were satisfied with both appearance and function. Conclusions The application of anatomy combined with an ultrasound knife in transaxillary endoscopic biplane breast augmentation is a promising way to achieve good breast shapes with high patient satisfaction and is worthy of clinical promotion and application.

Abstract
Background
It is important to correctly determine the ideal female breast anatomy and aesthetic proportions in order to prepare for surgery and establish its goals. Leaving the preference to the operating surgeons alone might leave unsatisfactory results, which especially leads to reoperation, quite often in the aspect of breast dimension.
Methods
This study was conducted using an online graphic questionnaire. We attempted to seek male and female perspectives toward their preferred ideal female breast size for breast augmentation, in order to provide up-to-date data to assist breast surgeons in attaining satisfactory surgical results.
Results
Sixty males and 67 females participated in the study comprising Asian major ethnicities of Malay, Chinese, and Indian. Universally, 46.6% of men and 53.5% of women preferred 30 mm diameter for the most ideal nipple-areola complex (NAC) size. For the perfect bust, they generally favored size C and D cup (37.8% and 38.5%, respectively).
Conclusion
The majority of women seek natural breast beauty and the longing for an oversized look appears to have infiltrated practice but these assumptions have finally been challenged by these findings.

Abstract
PURPOSE In the current study, the authors attempt to thoroughly investigate the concept of beauty from different perspectives in different historical periods and offer their personal thoughts about it. METHODS The authors performed a comprehensive and across-the-board literature review about 'beauty', including beauty from a philosophical perspective, beauty perception by human mind, beauty from a biopsychological perspective, beauty of the face, body and breast, models of beauty and beauty in cosmetic surgery. RESULTS From Plato to modern neuro-psychological studies, the concept of beauty has always been a theme for adamant debates and passionate thoughts. Different aspects of beauty, from intellectual to pure physical, have received a tremendous amount of attention. The true definition of the concept of beauty is still ambiguous, and there is not a unanimous explanation for it. It seems that the definition of beauty differs in every individual's mind and over the history of humankind. CONCLUSION Although beauty is a very important concept and the seek for achieving it is a very natural behavior, one must remember that the importance of beauty should not overshadow the fact that every human being is made up of similar internal organs. We strongly encourage the reader to look beyond the hedge, to be aware that each of us is made up of internal organs, beyond the external appearance.

Abstract
The possession of permanent, adipose breasts in women is a uniquely human trait that develops during puberty, well in advance of the first pregnancy. The adaptive role and developmental pattern of this breast morphology, unusual among primates, remains an unresolved conundrum. The evolutionary origins of this trait have been the focus of many hypotheses, which variously suggest that breasts are a product of sexual selection or of natural selection due to their putative role in assisting in nursing or as a thermoregulatory organ. Alternative hypotheses assume that permanent breasts are a by-product of other evolutionary changes. We review and evaluate these hypotheses in the light of recent literature on breast morphology, physiology, phylogeny, ontogeny, sex differences, and genetics in order to highlight their strengths and flaws and to propose a coherent perspective and a new hypothesis on the evolutionary origins of perennially enlarged breasts in women. We propose that breasts appeared as early as Homo ergaster, originally as a by-product of other coincident evolutionary processes of adaptive significance. These included an increase in subcutaneous fat tissue (SFT) in response to the demands of thermoregulatory and energy storage, and of the ontogenetic development of the evolving brain. An increase in SFT triggered an increase in oestradiol levels (E2). An increase in meat in the diet of early Homo allowed for further hormonal changes, such as greater dehydroepiandrosterone (DHEA/S) synthesis, which were crucial for brain evolution. DHEA/S is also easily converted to E2 in E2-sensitive body parts, such as breasts and gluteofemoral regions, causing fat accumulation in these regions, enabling the evolution of perennially enlarged breasts. Furthermore, it is also plausible that after enlarged breasts appeared, they were co-opted for other functions, such as attracting mates and indicating biological condition. Finally, we argue that the multifold adaptive benefits of SFT increase and hormonal changes outweighed the possible costs of perennially enlarged breasts, enabling their further development.
