Abstract
OBJECTIVES The success of a breast cancer screening program is highly dependent on adherence. We aimed to compare the differential effect of participation in breast cancer screening program versus opportunistic screening or symptomatic detection on tumour characteristics. METHODS We included women referred to our Breast Centre in 2015-2021: 321 from the breast cancer screening group (group 1) and 422 through opportunistic screening or due to symptomatic detection (group 2). We compared data on sociodemographics, breast cancer detection, clinical features and tumour characteristics. RESULTS A total of 10.6% of women in group 1 had breast symptoms and 63.8% had breast signs, with group 2 presenting higher proportions (57.6 and 77.8%, respectively, P < 0.001). The median tumour size in group 1 was smaller compared with group 2 (14 vs 17 mm, P < 0.001). A total of 8.7% of women in group 1 had nodal involvement whereas in group 2 the proportion corresponded to 19.0% (P < 0.001). No women in group 1 were diagnosed with metastasis, while metastases were found in 2.4% of those from group 2 (P = 0.005). There were no significant differences in molecular subtype of invasive tumours between the two groups. CONCLUSION The tumour characteristics of women who participated in the breast cancer screening program showed in almost all characteristics more favourable results in comparison with the group who underwent opportunistic screening or sought care due to symptoms. The lower clinical stage observed in those referred from the organised program reaffirms that it is an effective measure for early detection, diagnosis, and treatment.

Abstract
INTRODUCTION Screening is effective in reducing cancer-related morbidity and mortality. The aim of this study was to analyze the level of, and income-related inequalities in, screening attendance, in Portugal for population-based screening programs. METHODS Data from the Portuguese Health Interview Survey 2019 was used. Variables included in the analysis were self-reported: mammography, pap smear test, fecal occult blood test. Prevalence and concentration indices were computed at national/regional level. We analyzed: up-to-date screening (within recommended age/interval), under-screening (never or overdue screening), and over-screening (due to frequency higher than recommended or screening outside target group). RESULTS Up-to-date screening rates were 81.1%, 72%, and 40%, for breast, cervical and colorectal cancer, respectively. Never-screening was 3.4%, 15.7%, and 39.9%, for breast, cervical, and colorectal cancer, respectively. Over-screening related with frequency was highest for cervical cancer; in breast cancer, over-screening was observed outside recommended age, affecting one third of younger women and one fourth of older women. In these cancers, over-screening was concentrated among women with higher income. Never-screening was concentrated among individuals with lower income for cervical cancer and higher income for colorectal cancer. Beyond the recommended age, 50% of individuals never underwent screening for colorectal cancer and 41% of women never underwent screening for cervical cancer. CONCLUSION Overall, screening attendance was high, and inequalities were low in the case of breast cancer screening. The priority for colorectal cancer should be to increase screening attendance.

Abstract
Background High screening coverage can effectively reduce the mortality in breast and cervical cancer. Further research on extending the coverage of breast and cervical cancer screening in China is required. This study explored factors influencing women's "two-cancer" screening service utilization using an ecological approach. Methods Data were obtained from the National Health Services Survey (NHSS) conducted in 2018 in Jiangsu, China. A total of 3,500 women aged 18-64 years were included in the analysis. Chi-squared test, hierarchical multiple logistic regression analysis, and binary logistic regression analysis were performed. Results In total, 44.1% of the women had been screened for breast cancer (BC) and 40.9% for cervical cancer (CC). Breast cancer screening (BCS) and cervical cancer screening (CCS) differed significantly in the following common categories: age, gestational experiences, chronic disease status, body mass index (BMI), exercise, health checkup, marital status, number of children, employment, education, family doctors, and health records. In the results of hierarchical multiple logistic regression analysis, the explanatory power of the final model was 37.5% and the area under the receiver operating characteristic curve was 0.812. The results showed that being in the age group of 35-64 years, having gestational experiences, having chronic diseases, exercising, having a health checkup, being married, having children, and being employed were statistically significant positive predictors of "two-cancer" screening adherence. The household size was a barrier. For BCS, obesity was also a negative factor, and a higher overall self-related health status was a positive factor. Being married and living in households of three or more families were not predictors. For CCS, having health records was also positively significant, while having chronic disease did not influence adherence. Conclusion The findings provide an ecological explanation for women's BCS and CCS service utilization. Both proximal and distal factors should be considered to achieve a high coverage rate.

BREAST CANCER: BASIC AND CLINICAL RESEARCH 2022; 16:11782234221121001. [PMID: 36091183 PMCID: PMC9452820 DOI: 10.1177/11782234221121001] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2022] [Accepted: 08/08/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Early detection of breast cancer is a crucial factor in surviving the disease. This study aimed to investigate the mammography screening based on the theory of planned behavior (TPB) among rural women in Fasa and Shiraz cities, Iran. Methods: This study is a cross-sectional study performed on 800 female clients referring to rural health centers in Fasa and Shiraz cities in southern Iran in early 2021. The authors decided to send and distribute the electronic questionnaire form through the WhatsApp application in collaboration with the health staff of rural health centers for the people covered by these centers. Data gathering tools were a questionnaire on demographic characteristics, a questionnaire based on constructs of TPB, and behavior of mammography screening. Using the structural equation model (SEM), the TPB constructs and demographic variables were entered into the model. Data analysis was executed employing SPSS software version 26 and Amos version 24 (IBM Co., Ann Arbor, MI, USA). Analyzing the data was carried out using the 1-way analysis of variance (ANOVA), logistic regression, and structural equation analysis. During data analysis, various model indicators such as the goodness of fit, including comparative fit index (CFI), goodness-of-fit index (GFI), root mean square error of approximation (RMSEA), and chi-square index/df were evaluated. The significance level in all tests was considered 0.05. Results: The knowledge, attitude, and perceived behavioral control were the predictors of intention and behavior of mammography screening among the women. Among demographic variables, age, literacy, being menopausal, cancer in family, city, and ethnicity contribute more to the variance variation in TPB constructs. In this study, 7.2% of Persians, 8% of Qashqai Turks, and 4.5% of Arabs are contemplating going to mammography screening. In total, 6.8% (54 people) of all individuals intended to go mammography screening, and 5.4% (43 people) had a history of mammography screening. Goodness-of-fit indices (χ2 = 18.45, df = 10, n = 800, χ2/df = 1.845, RMSEA = 0.032, GFI = 0.90, non-normed fit index (NNFI) = 0.91) of conceptual model of this study indicate the suitability of the model. Conclusions: The results of the study indicated that the constructs of the TPB can predict mammography screening behaviors in rural women. It has also demonstrated that mammographic behavior can be improved in rural women using education based on the TPB model, emphasizing critical psychological factors of creating or changing behavior.

Abstract
We conducted a systematic review of a wide range of contextual factors related to cancer screening uptake that have been studied so far. Studies were identified through PubMed and Web of Science databases. An operational definition of context was proposed, considering as contextual factors: social relations directly aimed at cancer screening, health care provider and facility characteristics, geographical/accessibility measures and aggregated measures at supra-individual level. We included 70 publications on breast, cervical and/or colorectal cancer screening from 42 countries, covering a data period of 24 years. A wide diversity of factors has been investigated in the literature so far. While several of them, as well as many interactions, were robustly associated with screening uptake (family, friends or provider recommendation, provider sex and experience, area-based socio-economic status…), others showed less consistency (ethnicity, urbanicity, travel time, healthcare density …). Screening inequities were not fully explained through adjustment for individual and contextual factors. Context, in its diversity, influences individual screening uptake and lots of contextual inequities in screening are commonly shared worldwide. However, there is a lack of frameworks, standards and definitions that are needed to better understand what context is, how it could modify individual behaviour and the ways of measuring and modifying it.

Abstract
BACKGROUND Breast cancer is the most common type of cancer among women. Mammography is the most sensitive and important method for screening and early diagnosis of breast cancer. Considering the importance of using mammography in breast cancer screening, this study was performed to evaluate mammographic determinants. MATERIALS AND METHODS In the cross-sectional study, we surveyed 985 women over 40 years in Tehran concerning demographic characteristics: age, socioeconomic status, a problem in the breast, alcohol use, drug use, and health belief model. Logistic regression was used to identify determinant factors associated with mammography performance. RESULTS The results of this study showed that 42.1% (95% confidence interval [CI]: 38, 45) participant performed mammography at least once during their lifetime. Age (odds ratio [OR] = 4.252; 95% CI = 2.041-8.857); housing situation (OR = 1.706; 95% CI = 1.178-2.469); having breast problems (OR = 5.224; 95% CI = 3.501-7.795); socioeconomic status (OR = 1.855; 95% CI = 1.035-3.325); family income level (OR = 1.998; 95% CI = 1.028-3.884); alcohol consumption (OR = 2.676; 95% CI = 1.344-5.328); smoking (OR = 2.824; 95% CI = 1.418-5.623); self-efficacy (OR = 1.935; 95% CI = 1.242-3.015); perceived barriers (OR = 2.017; 95% CI = 1.348-3.019); self-care (OR = 4.901; 95% CI = 3.152-7.620); perceived susceptibility (OR = 1.971; 95% CI = 1.271-3.057) and perceived severity (OR = 1.830; 95% CI = 1.170-2.860) were mammography behaviors determinants. CONCLUSION The findings indicated that the rate of mammography screening among Tehranian women is low and highlights the need for developing a comprehensive national breast cancer control program, which should be considered as the priority for health-care providers. Furthermore, the identification of these factors can help to design an appropriate educational intervention that focuses on the benefits of mammography screening.

Health and health belief factors associated with screening and help-seeking behaviours for breast cancer: A systematic review and meta-analysis of the European evidence.

Abstract
PURPOSE The aim of this systematic review was to identify health or health belief factors associated with mammography attendance or with self-initiated medical help-seeking for breast cancer symptoms among women in Europe. METHODS Five databases were searched for articles published between 2005 and 2018. Meta-analyses were conducted for 13 factors related to screening attendance and two factors associated with help-seeking behaviour. Where there were too few studies to include in the meta-analysis, a narrative synthesis was undertaken. RESULTS Sixty-five studies were included. Never having had cervical screening (d = -.72, p < .001) and higher perceived barriers to mammography (d = -.40, p < .001) were associated with lower levels of screening attendance. Possessing health insurance (d = .49, p < .001), greater perceived benefits (d = .31, p < .001) and motivation (d = .36, p = .003) towards screening, and higher perceived seriousness (d = .24, p = .019) and susceptibility (d = .20, p = .024) towards breast cancer were associated with a higher level of screening attendance. Presenting with a non-lump symptom was associated with a longer time to presentation (d = .32, p < .001). The narrative synthesis revealed that previous benign breast disease was associated with a higher level of screening attendance but with a longer time to presentation. CONCLUSIONS The review identified key similarities in factors associated with screening and help-seeking behaviours which offer scope for combined interventions aimed at women that target both behaviours. Furthermore, the review highlighted that fewer studies have focused on help-seeking behaviour, despite two thirds of breast cancer cases being self-detected. Future research should further examine predictors of help-seeking behaviour including a focus on modifiable factors, such as BMI, and physical activity.

Abstract
In Lithuania, a Nationwide Breast Cancer (BC) Screening Program was launched in 2005, offering mammography for women aged 50 to 69 years, every other year. This study aimed to determine the trend in the attendance for mammography screening during 2006–2014 and to identify the factors that are predictive for participation in it. The study sample consisted of 1941 women aged 50–64 years, who participated in five cross-sectional biennial postal surveys of Lithuanian Health Behavior Monitoring, carried out in independent national random samples. The attendance for screening was identified if women reported having had a mammogram within the last two years. The proportion of women attending the screening was continuously increasing from 20.0% in 2006 up to 65.8% in 2014. The attendance for BC screening was associated with the participation in cervical cancer screening. A higher level of education, living in a city, frequent contact with a doctor, and healthy behaviors (fresh-vegetable consumption, physical activity, and absence of alcohol abuse) were associated with higher participation rates in BC screening. To increase BC screening uptake and to reduce inequalities in attendance, new strategies of organized BC screening program using systematic personal invitations are required in Lithuania.

Abstract
Vaccination is an effective strategy to prevent tetanus, and in Portugal this service is provided free of charge. Despite this, immigrants reported lower tetanus vaccination coverage than did Portuguese natives. The objective of this study was to identify sociodemographic, migration-related, and access-to-care factors associated with tetanus vaccination coverage among adult immigrants, using data from the Portuguese National Health Survey 2014. For the sample of 1277 immigrants aged ≥18 years, we estimated self-reported tetanus vaccination within the preceding 10 years and its determinants using complex samples logistic regression. The overall self-reported tetanus vaccination coverage was 79.5% (95% CI: 75.8-82.8). Age (adjusted odd ratio (aOR) per 1 year age increase = 0.97, 95% CI: 0.95-0.99), higher household income per adult (aOR = 0.42, 95% CI: 0.19-0.96), having Portuguese citizenship (aOR = 2.30, 95% CI: 1.25-4.24), having private health insurance (aOR = 1.99, 95% CI: 1.06-3.71), and contact with family/general physician in the last 12 months (aOR = 1.59, 95% CI: 1.01-2.51) were associated with self-reported tetanus vaccination coverage among adult immigrants. We also found significant disparities in coverage between regions of residence. This study identified several determinants associated with self-reported tetanus vaccination coverage among adult immigrants in Portugal. These findings may help policymakers to design specific interventions to increase tetanus vaccination coverage among this population.

Abstract
Breast cancer (BC) is the most frequent malignancy in Portuguese women, and more than half of the registered cases live in the south of the country. The main of this study was to characterize patients with locoregional and metastatic incident BC living in the Southern Portuguese and Madeira regions in 2005-2012 according to demographic, clinical and contextual characteristics. Additionally it aimns to find the associations and relative influences of these factors with locoregional or metastatic disease at diagnosis. After a descriptive approach, binary logistic regression models were used to estimate factors related to the presence of metastatic disease at diagnosis. A final multiple regression model was developed and presented graphically as a nomogram. The median age at diagnosis was 60.84 years, being statistically lower in locoregional cases (P < 0.001). Most patients presented a locoregional disease (78.4%) of unspecified location (44.5%) and had a ductal carcinoma (73.1%). The Lisbon region represented 50.5% of the analyzed cases. Metastatic disease significantly decreased over the period under analysis ( ≈ 7%/year). Demographic (age at diagnosis ≥ 50 years), clinical (lobular and 'other' morphologies, unspecified location) and contextual (residence in Portalegre) characteristics were statistically correlated with the presence of metastatic disease at the time of BC diagnosis in univariate logistic regression, with all but the last maintaining their significance in a multivariate model. Cases with metastatic BC disease at diagnosis are decreasing; however, additional information on their characteristics can improve the alignment of public health strategies, thus strengthening this trend, and contributing to the development of a graphically tailored screening tool.

Abstract
BACKGROUND Female breast cancer incidence rates have been increasing in Portugal for years. We, therefore, conducted the first nationwide breast cancer study to assess regional differences. METHODS Cases were obtained from population-based cancer registries covering the country's Mainland (South, North, Centre), as well as the two Autonomous Regions (Azores and Madeira), for the time-period 1998 through 2011. Analyses were restricted to ages 30-84 years and stratified by region. We used the age-period-cohort (APC) framework to complement standard descriptive techniques and to forecast future trends. Estimable APC parameters included net drift, longitudinal age-specific incidence rate curves, and fitted age-specific incidence rate ratios. RESULTS There were 71 545 breast cancer cases diagnosed in Portugal at ages 30-84 years from 1998 to 2011. The South presented the highest age-standardized rate (155.8/100 000), while the North presented the fastest rate of increase (3.6%/year). Age-specific statistical interactions were observed between regions. Younger women in the North revealed a decreased risk of developing breast cancer compared to women from the same age group in the South and Centre, while that risk was reversed in older women (p < 0.05). We estimate that from 2014 onwards, the North might rank first among all regions. CONCLUSION The variant patterns observed could be due to a combination of different screening practices and/or exposure to risk factors across regions. Disease heterogeneity among younger and older women may also explain part of the differences in age-specific rates. These results justify continued monitoring of breast cancer incidence by region.

Abstract
INTRODUCTION Understanding the patterns of mammography use and monitoring changes in use are essential to improving national health policy for breast cancer control. We aimed to describe the use of mammography in Portugal and to identify the determinants of its nonuse and underuse by examining data from the National Health Survey 2014. METHODS We analyzed data on 8,758 women aged 30 years or older. We defined women at an eligible age for mammography as women aged 45 to 69. Women who reported a previous mammography test were classified as ever-users and grouped according to time since the most recent test. We computed the prevalence of mammography use, and we used Poisson regression models to obtain age-adjusted and education-adjusted prevalence ratios and 95% confidence intervals. RESULTS The overall prevalence of mammography use was 80.0%, whereas nonuse was 20.0% and underuse 27.3% among users. The prevalence of nonuse and underuse were lower and associations with sociodemographic characteristics, use of health care services, and behavioral factors were stronger among women aged 45 to 69 than among women aged 30 to 44 and women aged 70 or older. The prevalence of mammography use was generally higher in the northern areas of Portugal than in southern areas and varied by marital status, educational level, and household size. A more frequent use of health care services and healthier behaviors were associated with lower prevalences of both nonuse and underuse. CONCLUSION This study illustrates inequalities in mammography use and provides useful information for better allocation of resources in breast cancer screening.

Abstract
Breast cancer (BC) is the most frequent tumour affecting women all over the world. In low- and middle-income countries, where its incidence is expected to rise further, BC seems set to become a public health emergency. The aim of the present study is to provide a systematic review of current BC screening programmes in WHO European Region to identify possible patterns. Multiple correspondence analysis was performed to evaluate the association among: measures of occurrence; GNI level; type of BC screening programme; organization of public information and awareness campaigns regarding primary prevention of modifiable risk factors; type of BC screening services; year of screening institution; screening coverage and data quality. A key difference between High Income (HI) and Low and Middle Income (LMI) States, emerging from the present data, is that in the former screening programmes are well organized, with approved screening centres, the presence of mobile units to increase coverage, the offer of screening tests free of charge; the fairly high quality of occurrence data based on high-quality sources, and the adoption of accurate methods to estimate incidence and mortality. In conclusion, the governments of LMI countries should allocate sufficient resources to increase screening participation and they should improve the accuracy of incidence and mortality rates.

Abstract
BACKGROUND Cancer screening has contributed to downward trends in cancer mortality, but is also associated with adverse effects, which highlights the importance of promoting the participation based on informed decisions. OBJECTIVES We aimed to describe the use of cancer screening (either in organized programmes or as opportunistic screening), awareness of organized programmes and perception of its potential benefits and adverse effects, depicting possible sex differences. DESIGN AND METHODS We evaluated 1624 Portuguese-speaking dwellers, aged between 16 and 79 years, through face-to-face interviews. To quantify sex differences, adjusted prevalence ratios and respective 95% confidence intervals were computed using Poisson regression. RESULTS Among eligible age groups, the lifetime prevalence of screening for breast and cervical cancers was 89.8 and 71.9%, respectively. The prevalence was 23.7% for colorectal cancer and no significant sex differences were observed. Prostate cancer screening was reported by 63.8% of men. Over half of the participants referred that cancers such as prostate, skin, lung and stomach should be screened for, in addition to those for which organized programmes are recommended. Reassurance by negative results was identified as the main potential benefit of screening by nearly one-third of men and women. Anxiety while waiting for results was the most mentioned potential adverse effect (60.4%); men refer less often this and financial costs, although statistical significance of these results was borderline. CONCLUSIONS This study provides a benchmark to plan and monitor the effects of awareness-raising interventions, as well as for international comparisons across countries with different cancer prevention and control structures.

Abstract
OBJECTIVE To evaluate the first 10 years of operation of the population-based breast cancer screening programme implemented in the Northern Region of Portugal, using selected recommended standard performance indicators. METHODS Data from women aged 50-69 screened with two-view mammography, biennially, in the period 2000-2009, were included. Main performance indicators were compared with the recommended levels of the European Guidelines. RESULTS A total of 202,039 screening examinations were performed, 71,731 (35.5%) in the initial screening and 130,308 (64.5%) in the subsequent screening. Coverage rate by examination reached 74.3% of the target population, in the last period evaluated. Recall rates were 8.1% and 2.4% and cancer detection rates were 4.4/1000 and 2.9/1000 respectively, for initial and subsequent screenings. The breast cancer detection rate, expressed as a multiple of the background expected incidence was 3.1 in initial screen and 2.2 in subsequent screen. The incidence of invasive interval cancers met the desirable recommended levels both the first and second years since last screening examination, in the initial and subsequent screenings. Invasive tumours <15mm were 50.4% and 53.8% of the invasive cancers detected in initial and subsequent screenings. Less favourable size, grading and biomarkers expression were found in interval cancers compared to screen-detected cancers. CONCLUSIONS Breast cancer screening programme in the Northern Region of Portugal was well accepted by the population. Most of the performance indicators were consistent with the desirable levels of the European Guidelines, which indicate an effective screening programme. Future research should verify the consistency of some of these results by using updated information from a larger population.

Abstract
This paper analyze the association between height and chronic diseases in Portugal and the extent to which this relationship is mediated by education. The sample upon which the analysis is based comprised those participants in the 2005/2006 Portuguese National Health Interview Survey (n=28,433) aged 25-79. Logistic regressions measured the association of height with ten chronic diseases, adjusting for age, lifestyle, education, and other socioeconomic factors. Among women, an additional centimeter in stature significantly decreased the prevalence of asthma, chronic pain, and acute cardiac disease, by 0.057, 0.221, and 0.033 percentage points, respectively. Also, mental disorders were significantly less prevalent in the last quartile of height. Among men, an additional centimeter in height was associated with a 0.074 lower prevalence of asthma, and men in the last quartile of height were significantly less at risk of acute cardiovascular disease. There was no significant association between height and the risk of diabetes, high blood pressure, cancer, and pulmonary diseases. As for the impact of education, women with a tertiary level were on average 5.3cm taller than those with no schooling; among men, the difference was almost 9cm. Adjusting for education reduced the height-related excess risk of ill health by 36% on average among men, and by 7% among women. The analysis indicates that there is a significant association of height with several chronic conditions, and that education plays a mediating role in the height-health connection. By emphasizing the role of height and education as determinants of chronic conditions, this paper also highlights the role of conditions related to childhood health and socioeconomic background.

Abstract
A lipid-cisplatin conjugate was synthesized for super-molecular assembly with lipids to form a new generation of liposomal cisplatin formulation, lipocisplatin. In vitro, lipocisplatin has higher efficacy in human ovarian cancer A2780 and human breast cancer MCF-7 with the murine breast cancer cell line 4T1 which is currently an established model for stage IV breast cancer as the most sensitive strain. Moreover, lipocisplatin demonstrated a greater MTD value and relatively longer blood circulation as compared to cisplatin. Lipocisplatin preferentially accumulate drugs to the tumor site, resulting in a better tumor inhibition efficacy. Moreover, lipocisplatin exceeds the size cutoff for kidney clearance, hence it bypasses the nephrotoxicity of cisplatin which is a major curse of one of the most efficient anticancer drugs nowadays in clinic. The results here indicated lipocisplatin may be translated into a new generation of liposomal based cisplatin drug in clinic.

Abstract
BACKGROUND Understanding the patterns of cervical cytology use in preventive care may provide useful information for an efficient transition from opportunistic screening to organized programmes. We aimed to identify the determinants of non-use and underuse of cervical cytology in Portuguese women. METHODS As part of the fourth National Health Survey (2005/2006), 2191 women aged between 25 and 64 years were evaluated. The previous use of cervical cytology was classified as never or ever, and, among the latter, those having performed the latest cytology testing >5 years before were considered to underuse cervical cytology. We assessed the determinants of non-use and underuse through age- and education-adjusted odds ratios (ORs) and corresponding 95% confidence intervals (95% CIs). RESULTS Overall, 23.5% of women had never used cervical cytology and 10.7% reported underuse. This prevalence increased with age and decreased with education and income. Compared with the national mean, the lowest risk of non-use and underuse was observed in Norte (non-use: OR = 0.31, 95% CI: 0.23-0.42; underuse: OR = 0.60, 95% CI: 0.40-0.91) and the highest in Alentejo (non-use: OR = 2.33, 95% CI: 1.78-3.06; underuse: OR = 2.37, 95% CI: 1.43-3.93). Women without a private health insurance (OR = 2.65, 95% CI: 1.29-5.47), who had no doctor appointments in the preceding 3 months (OR = 2.06, 95% CI: 1.22-3.48) and those who had never performed a mammography (OR = 17.78, 95% CI: 9.09-34.78) were more likely to have never performed a cervical cytology. CONCLUSION This study shows inequalities in the use of cervical cancer screening in Portugal and provides useful information for a better allocation of resources for cancer screening.
