Prevalence and determinants of breast and cervical cancer screening among women aged between 30 and 49 years in India: Secondary data analysis of National Family Health Survey - 4

Multi-Scale Vision Transformer with Optimized Feature Fusion for Mammographic Breast Cancer Classification

Background: Breast cancer remains one of the leading causes of mortality among women worldwide, highlighting the critical need for accurate and efficient diagnostic methods. Methods: Traditional deep learning models often struggle with feature redundancy, suboptimal feature fusion, and inefficient selection of discriminative features, leading to limitations in classification performance. To address these challenges, we propose a new deep learning framework that leverages MAX-ViT for multi-scale feature extraction, ensuring robust and hierarchical representation learning. A gated attention fusion module (GAFM) is introduced to dynamically integrate the extracted features, enhancing the discriminative power of the fused representation. Additionally, we employ Harris Hawks optimization (HHO) for feature selection, reducing redundancy and improving classification efficiency. Finally, XGBoost is utilized for classification, taking advantage of its strong generalization capabilities. Results: We evaluate our model on the King Abdulaziz University Mammogram Dataset, categorized based on BI-RADS classifications. Experimental results demonstrate the effectiveness of our approach, achieving 98.2% for accuracy, 98.0% for precision, 98.1% for recall, 98.0% for F1-score, 98.9% for the area under the curve (AUC), and 95% for the Matthews correlation coefficient (MCC), outperforming existing state-of-the-art models. Conclusions: These results validate the robustness of our fusion-based framework in improving breast cancer diagnosis and classification.

Barriers and facilitators of pap-smear test uptake in Asia: a systematic review

BACKGROUND

In addition to the establishment of screening procedures, it is important to identify the barriers and facilitators for promoting preventive behavior. Many studies have been conducted in the field of investigating the factors affecting Pap smear test uptake and the barriers related to it. However, a systematic approach is still needed. Therefore, this present study was conducted with the aim of systematically reviewing the barriers and facilitators of Pap smear test uptake in Asia.

METHODS

To collect the data, searches were performed in PubMed, WOS, ProQuest, Scopus and Cochrane databases from January 1, 2018 to January 15, 2025. Two people separately and independently evaluated the quality of the studies by Newcastle-Ottawa Scale. To conceptualize influential factors, barriers and facilitators of Pap-smear test uptake among Asian women, a theoretical thematic analysis was applied.

RESULTS

A search yielded 4057 records, of which 44 documents discussing the determinants, barriers, and facilitators of Pap smear uptake were included in the review. There were economic, social, awareness, test and provider characteristics, and lifestyle and health behaviors dimensions in both categories of barriers and facilitators. In addition, two religious and psychological dimensions were included in the barriers category. In total, 55 components representing barriers and 51 components representing facilitators were identified.

CONCLUSION

To improve Pap smear uptake, implement financial assistance and comprehensive insurance coverage. Enhance community engagement through outreach and support groups, provide counseling, and create positive messaging. Increase accessibility with mobile clinics, flexible hours, and train providers. Promote health education and offer incentives to motivate women to participate in screenings.

Regional Variations and Inequalities in Testing for Early Detection of Breast and Cervical Cancer: Evidence From a Nationally Representative Survey in India

BACKGROUND

The burden of cancer in India has been rising, yet testing for early detection remains low. This study explored inequalities in the uptake of breast cancer (BC) examination and cervical cancer (CC) among Indian women, focusing on socioeconomic, regional, and educational differences.

METHODS

Data from the 2019-21 National Family Health Survey (n = 353,518) were used to assess the uptake of BC examination and CC testing. Inequalities were quantified using the slope index of inequality (SII), relative index of inequality (RII), and relative concentration index (RCI). SII measured absolute inequality, while RII and RCI assessed relative inequality between disadvantaged and advantaged groups.

RESULTS

The ever uptake of tests for early detection of BC and CC were low at 9 and 20 per 1,000 women, respectively. Higher uptake was observed among women from the richest households compared to the poorest (SII: 1.1 for BC and 1.8 for CC). The magnitude of relative socioeconomic inequalities was more pronounced in rural areas (RCI: 22.5 for BC and 21.3 for CC) compared to urban areas. Similarly, higher-educated women were 4.84 times (RII: 4.84) and 2.12 times (RII: 2.12) more likely to undergo BC examination and CC testing, respectively, compared to non-educated women. The Northeastern region exhibited greater socioeconomic inequality, while the Western region showed more education-based inequality.

CONCLUSION

The lower uptake of BC examination and CC testing and the marked inequalities underscore the need for targeted interventions to improve access and utilization of testing services, especially among lower-educated women, and those in rural areas.

Cytotoxic activity of Cyrtostachys renda extracts and fractions against MCF-7 and HeLa cancer cells through cell cycle arrest and apoptosis induction mechanism

In traditional medicine, Cyrtostachys renda has been used for its many bioactive components that are good for people's health. This research assessed the cytotoxic effects of extracts and fractions against Michigan Cancer Foundation-7 (MCF-7) and Henrietta Lacks (HeLa) cell lines. The extracts and fractions of root and fruit assess cytotoxic activities and inhibitory mechanisms against the MCF-7 and HeLa cancer cell lines, respectively. The fruit and roots of C. renda were extracted using the liquid-liquid method. The sample concentrations evaluated included extracts 31.5-1000 μg/mL, fractions 15.625-500 μg/mL, and doxorubicin 2-0.0625 μg/mL. Cytotoxicity was evaluated on MCF-7 and HeLa cells using an MTT assay. Morphological alterations were subsequently discovered utilizing an inverted microscope. Flow cytometry was utilized to find out the cell cycle's distribution and the apoptosis characteristics. The different parts and extracts showed cytotoxic effects on HeLa and MCF-7 cells, with IC50 values ranging from 30.69 ± 0.47 to 787.89 ± 1.77 µg/mL. Cell cycle studies showed that fraction A4 inhibited the cell cycle in MCF-7 cells at the G1 phase followed by the G2/M and S phases, while fraction B5 inhibited the cell cycle in HeLa cells at the G2/M phase. Both fractions showed the ability to induce apoptosis against MCF-7 and HeLa cells. The results showed that the fractions A4 and B5 showed cytotoxic activity against MCF-7 and HeLa cells by cell cycle arrest and apoptosis induction.

Factors associated with cervical cancer screening among women of reproductive age in Ghana

BACKGROUND

Cervical cancer remains a leading cause of cancer-related deaths among women in Ghana and other Sub-Sahara African (SSA) countries. Despite the importance of early diagnosis for timely treatment and death prevention, cervical cancer screening among women in developing countries remain very low. Nonetheless, there is a paucity of research examining the factors associated with screening uptake among women of reproductive age in Ghana. Thus, this study fills the scholarly void and contributes to the existing literature by examining the determinants of cervical cancer screening in Ghana.

METHODS

Utilizing data from the 2022 Ghana Demographic and Health Survey (GDHS) (N = 15,014 women), and by employing logistic regression models for a cross-sectional analysis, this study evaluated the factors associated with cervical cancer screening in Ghana.

RESULTS

Women with tertiary educational attainment (OR = 4.140; 95%CI: 2.960 5.789; p < 0.001), from the richer (OR = 1.968; p < 0.001) and richest households (OR = 2.492; p < 0.001), the married/living with partner (OR = 1.773; 95%CI:1.372 2.290; p < 0.001), the widowed/divorced/separated (OR = 1.888; 95%CI:1.320 2.701; p < 0.001), owners of valid health insurance card (OR = 1.356; 95%CI:1.086 1.693; p < 0.01), visitation to health facility in the past 12 months (OR = 1.312; 95%CI: 1.082 1.590; p < 0.001), those who watched television at least once in a week (OR = 1.395; 95%CI: 1.055 1.846; p < 0.001), as well as those who listened to radio at least once in a week (OR = 1.509; 95%CI: 1.228 1.853; p < 0.001), were all significantly more associated with cervical cancer screening in the study context. Also, ethnicity, religion, and the region of residence significantly predicted cervical cancer screening in the study context.

CONCLUSION

Cervical cancer screening in Ghana can be improved by addressing socioeconomic and geographical disparities in the country's healthcare system. To ensure early detection, timely treatment or care and prevention of cervical cancer-related deaths in the country, there must be coordinated efforts by the government of Ghana to improve healthcare access and surveillance systems for cervical cancer cases, particularly, in geographically disadvantage areas.

Women's empowerment and its influence on the uptake of breast cancer screening in Tanzania: an analysis of 2022 Tanzania demographic health survey data

BACKGROUND

Breast cancer is the second most commonly diagnosed cancer worldwide, with a high mortality rate in developing countries, including sub-Saharan Africa. Screening is one way to ensure early detection and management of breast cancer, and it is influenced by several factors. Education and socio-economic status may also affect the utilization of breast cancer screening services as these impact decision-making. This study aimed to investigate women's empowerment and its influence on the uptake of breast cancer screening among women in Tanzania.

METHODS

This study utilized the 2022 Tanzania Demographic and Health Survey data, and included 4216 women aged 20 to 49 years. Women empowerment variables used include social independence, decision-making, ownership of assets, and attitude towards violence. Statistical Package for Social Sciences version 26 was used for data cleaning and analysis. Descriptive statistics and bivariate analysis were done, including a multivariate logistic regression to assess the level of association between independent variables with breast cancer screening.

RESULTS

Findings indicate that the prevalence of breast cancer screening is 5.2%. Age, education level, literacy, ownership of assets, attitude towards violence, and decision making are associated with ever going for breast cancer screening. Women aged 45 to 49 years (AOR = 6.28, 95% CI = 6.27-6.28), those with secondary or higher education (AOR 1.1, 95% CI = 1.05-1.06), literate women (AOR = 1.13, 95% CI = 1.13-1.13), those who own a house (AOR = 3.08, 95% CI = 3.08-3.09), who jointly decide on their healthcare with partners on healthcare (AOR = 1.18, 95% CI = 1.18-1.19) had significantly higher odds of going for breast cancer screening.

CONCLUSION

Women's empowerment is significantly associated with the likelihood of engaging in breast cancer screening. Empowered women are more likely to undergo screening. Focus should be on empowering women through education, businesses, and community involvement. Country-specific interventions and breast cancer screening awareness campaigns should include empowerment initiatives to promote screening uptake.

Global epidemiology of breast cancer based on risk factors: a systematic review

BACKGROUND

Numerous reviews of the epidemiology and risk factors for breast cancer have been published previously which heighted different directions of breast cancer.

AIM

The present review examined the likelihood that incidence, prevalence, and particular risk factors might vary by geographic region and possibly by food and cultural practices as well.

METHODS

A systematic review (2017-2022) was conducted following Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, reporting on epidemiological and risk factor reports from different world regions. Medical Subject Heading (MeSH) terms: "Breast neoplasm" "AND" country terms such as "Pakistan/epidemiology", "India/epidemiology", "North America/epidemiology", "South Africa/epidemiology" were used to retrieve 2068 articles from PubMed. After applying inclusion and exclusion terms, 49 papers were selected for systematic review.

RESULTS

Results of selected articles were summarized based on risk factors, world regions and study type. Risk factors were classified into five categories: demographic, genetic and lifestyle risk factors varied among countries. This review article covers a variety of topics, including regions, main findings, and associated risk factors such as genetic factors, and lifestyle. Several studies revealed that lifestyle choices including diet and exercise could affect a person's chance of developing breast cancer. Breast cancer risk has also been linked to genetic variables, including DNA repair gene polymorphisms and mutations in the breast cancer gene (BRCA). It has been found that most of the genetic variability links to the population of Asia while the cause of breast cancer due to lifestyle modifications has been found in American and British people, indicating that demographic, genetic, and, lifestyle risk factors varied among countries.

CONCLUSION

There are many risk factors for breast cancer, which vary in their importance depending on the world region. However, further investigation is required to better comprehend the particular causes of breast cancer in these areas as well as to create efficient prevention and treatment plans that cater to the local population.

Patterns in the prevalence and wealth-based inequality of cervical cancer screening in India

BACKGROUND

Cervical cancer is the second leading cause of deaths due to cancer among women in India. This study assesses the prevalence of cervical cancer screening among women in the 30 to 49 years age-group and its relation to demographic, social and economic factors. The equity in the prevalence of screening is studied with respect to the women's household wealth.

METHODS

Data from the fifth National Family Health Survey are analyzed. The adjusted odds ratio is used to assess the prevalence of screening. The Concentration Index (CIX) and the Slope Index of Inequality (SII) are analyzed to assess the inequality.

RESULTS

The average national prevalence of cervical cancer screening is found to be 1.97% (95% C.I, 1.8-2.1), ranging from 0.2% in West Bengal and Assam to 10.1% in Tamil Nadu. Screening is significantly more prevalent among the following demographics: educated, higher age group, Christian, scheduled caste, Government health insurance coverage, and high household wealth. Significantly lower prevalence is found among Muslim women, women from scheduled tribes, general category castes, non-Government health insurance coverage, high parity, and those who use oral contraceptive pills and tobacco. Marital status, place of residence, age at first sexual activity, and IUD usage are not significant influencers. At the national level, CIX (0.22 (95% C.I, 0.20-0.24)) and SII (0.018 (95% C.I, 0.015-0.020)) indicate significantly higher prevalence of screening among women from the wealthier quintiles. Significantly higher screening prevalence among wealthier quintiles in the North-East (0.1), West (0.21) and Southern (0.05) regions and among the poor quintiles in the Central (-0.05) region. Equiplot analysis shows a "top inequality pattern" in the North, North-East and Eastern regions, with overall low performance where the rich alone manage to avail screening. The Southern region exhibits an overall progress in screening prevalence with the exception of the poorest quintile, which is left behind. Pro-poor inequality exists in the Central region, with significantly higher prevalence of screening among poor.

CONCLUSION

The prevalence of cervical cancer screening is very low (2%) in India. Cervical cancer screening is substantially higher among women with education and Government Health insurance coverage. Wealth-based inequality exists in the prevalence of cervical cancer screening and the prevalence is concentrated among the women from wealthier quintiles.

King Abdulaziz University Breast Cancer Mammogram Dataset (KAU-BCMD)

The current era is characterized by the rapidly increasing use of computer-aided diagnosis (CAD) systems in the medical field. These systems need a variety of datasets to help develop, evaluate, and compare their performances fairly. Physicians indicated that breast anatomy, especially dense ones, and the probability of breast cancer and tumor development, vary highly depending on race. Researchers reported that breast cancer risk factors are related to culture and society. Thus, there is a massive need for a local dataset representing breast cancer in our region to help develop and evaluate automatic breast cancer CAD systems. This paper presents a public mammogram dataset called King Abdulaziz University Breast Cancer Mammogram Dataset (KAU-BCMD) version 1. To our knowledge, KAU-BCMD is the first dataset in Saudi Arabia that deals with a large number of mammogram scans. The dataset was collected from the Sheikh Mohammed Hussein Al-Amoudi Center of Excellence in Breast Cancer at King Abdulaziz University. It contains 1416 cases. Each case has two views for both the right and left breasts, resulting in 5662 images based on the breast imaging reporting and data system. It also contains 205 ultrasound cases corresponding to a part of the mammogram cases, with 405 images as a total. The dataset was annotated and reviewed by three different radiologists. Our dataset is a promising dataset that contains different imaging modalities for breast cancer with different cancer grades for Saudi women.
