A review of barriers and facilitators to mammography in Asian women

Unlocking insights: exploring mammography beliefs among Teshie community mothers - a qualitative exploratory descriptive study

BACKGROUND

Breast cancer is a global concern, especially for women of African descent, with rising cases in Ghana. While awareness and diagnostic screening have improved, studies in Ghana and many African countries have prioritised breast self-examinations, with limited focus on mammography.

OBJECTIVE

Our study explores beliefs and attitudes towards mammography screening among mothers at Teshie Community in Ghana.

METHODS

The study methodology was qualitative and an exploratory design was used. Convenience sampling was used to select 30 participants until saturation was reached. Indepth, one-on-one interviews were conducted with a semistructured interview guide with probes until saturation was reached. Then data were audiotaped audiotaped, transcribed and coded. Content analysis was done to generate themes and subthemes.

FINDINGS

Most participants, 93%, had not undergone mammography screening. Only two individuals (7%) had experienced mammography screening. The study identified two major themes: beliefs and perceptions regarding mammography, and attitudes towards mammography screening. Participants generally displayed limited knowledge of mammography screening, along with mixed attitudes and varying degrees of motivation. Notably, many participants enjoyed strong spousal support for mammography screening.

CONCLUSION

It was recommended that nurses should create awareness of mammography to increase the knowledge of women and the general population about mammography, as this is believed to increase the uptake of mammography screening.

Do women with a history of breast cancer recommend risk-based breast cancer screening? An in-depth interview study

Objectives

Personalizing screening recommendations could enhance efficiency, support timely detection, and optimize resource use. This study explores women's perceptions of the facilitators and barriers to current screening guidelines and the implementation of risk-based screening (RBS) for breast cancer in Singapore.

Methods

Individual semi-structured interviews were conducted with 11 women aged 21 and above with a history of breast cancer. Data coding and thematic analysis were guided by the Health Belief Model (HBM).

Results

Five themes were identified and mapped to the Health Belief Model (HBM): (1) Knowledge and beliefs, (2) Access to mammography screening, (3) Social influences, (4) Healthcare delivery, and (5) Needs and preferences for RBS implementation. Key barriers to screening adherence included low perceived susceptibility, cost concerns, and accessibility issues. Factors that could improve adherence included social influences promoting breast health awareness, reminders from trusted healthcare professionals (HCP), and confidence in affording screening and treatment. Participants were generally receptive to RBS and valued personalized recommendations, but concerns were raised about risk prediction accuracy, insurance implications, and potential negative reactions to risk results.

Conclusion

This study identifies challenges and enablers for enhancing breast screening in Singapore, based on the experiences of breast cancer survivors. Participants supported RBS for routine screening. Successful RBS implementation requires improved health literacy, HCP engagement, and accessible healthcare. Women's acceptance will rely on research to refine prediction accuracy and communication of risk results.

Social health determinants associated with mammography performance according to the 2013 and 2019 National Health Survey

Mammography is one of the main methods available for breast cancer screening in Brazil. However, differences in timely access and performance of the exam can be highlighted based on social determinants of health, considered relevant due to their influence on the health situation of a population. Thus, the present study aimed to identify the social determinants of health associated with access to and performance of mammography in Brazilian women. Cross-sectional and analytical study, based on secondary data from the National Health Survey (NHS) from 2013 and 2019 in Brazil. The main determinants of women who did not take the exam during the evaluated period were: aged 65 to 69 years, mixed race and black, living with more than three people, with incomplete primary education, in the 1st quintile of socioeconomic income, without health insurance, registered with the Family Health Strategy (FHS), and residents of the North and Northeast regions. There was a significant improvement in access to mammography exams in all states; however, structural factors, such as economic income, color, level of education, and age group were evident in why mammograms were not performed.

A Scoping Review of 20 Years Breast Cancer Screening Programs in Iran

Background

Breast cancer (BC) is the leading cancer among women globally. Early detection through screening is vital for reducing mortality, complementing advancements in treatment.

Methods

We aimed to overview BC screening practices in Iran over two-decades to inform policymakers for future research directions and prompt timely diagnoses. A scoping review was conducted on BC studies in Iran from 2000 to 2023, following PRISMA guidelines.

Results

We analyzed 129 articles on BC in Iranian women, and finding six main areas.

Conclusion

Iran's health system lacks an organized BC screening initiative, facing challenges like inadequate infrastructure, sociocultural barriers, unintegrated health insurance packages, and limited research on key indicators.

Disparities in Health Screening Completion Status for Adults with Severe Disabilities Compared to Adults With No Disabilities in Korea: A Retrospective Study of Electronic Health Records

Health screening is crucial for individuals with disabilities because they are likely to experience preventable health challenges, leading to poor health outcomes. However, there is limited insight into barriers to health screening for them after arriving at a healthcare facility. Thus, this study aimed to explore the association between disability status/type and health screening test completion and the reasons for incomplete tests after arriving at a healthcare facility. We reviewed 767 electronic health records of individuals who underwent health screening in a healthcare facility over one year. Chi-square or Fisher's exact tests were used to explore differences in test completion. Levesque's access to care framework was used to categorize the reasons for incomplete tests into provider- and patient-related domains. The findings showed associations between disability status and health screening completion. Both provider- and patient-related barriers were recorded as the reasons for incomplete tests for cases with disabilities. The associations found suggest potential disparities individuals with disabilities experience upon arrival at healthcare facilities. Further prospective studies are needed to test and validate the healthcare utilization disparities in disability.

Global trend of cervical cancer among women aged 55 and older from 2010 to 2019: An analysis by socio-demographic index and geographic regions

Objective

This study describes the 2010-2019 trend of cervical cancer (CC) in women over 55 by socio-demographic index (SDI) and geographical regions.

Methods

We obtained data on CC annually from 2010 to 2019 from the 2019 Global Burden of Disease Study (GBD) to analyze the incidence, death and prevalence rates, and disability-adjusted life years (DALYs) associated with CC across different parameters such as global trend, age groups, SDI, continents, World Bank Regions, World Health Organization (WHO) regions, GBD regions, and National and territorial division. This analysis covers data from 204 countries and territories from 1990 to 2019.

Results

There were 236,228 CC incidence cases worldwide in 2019, which is a 1.27-fold increase from 2010. Global CC deaths also increased to 169,304 cases in 2019, reflecting a 1.24-fold increase. CC prevalence increased to 769,925 cases in 2019, representing a 1.4-fold rise. The number of CC DALYs globally increased to 3,835,979 cases in 2019, reflecting a 1.24-fold increase. Incidence, death, prevalence, and DALY numbers of CC increased across all age groups females in the 65-69 years age group experienced the highest increase. Middle SDI countries had the highest incidence, death, prevalence, and DALY numbers, while low SDI countries showed increasing trends. Asia exhibited the highest incidence, death, prevalence, and DALY numbers of CC. Upper middle-income countries had the highest incidence, death, prevalence, and DALY numbers, with the highest decreases in these rates except the prevalence rate. The Western Pacific Region showed the highest incidence, death, prevalence, and DALY numbers, with declining rate trends. The Republic of Kiribati showed the highest incidence, death, prevalence, and DALY numbers.

Conclusion

Based on the study results, it is clear that although the global trend of epidemiological indicators of CC is decreasing, the largest proportion of the decreasing trend is related to developing countries. But in regions of Africa and Asia that have a lower level of development, sometimes these indicators show upward trends, which shows the worsening of the problem in these regions and the need for serious policies and plans to implement comprehensive vaccination, screening, and promotion interventions. People's awareness is necessary in the field of better disease control.

Prevalence of Breast Cancer Screening in Asia: Systematic Review and Meta-Analysis

BACKGROUND

Breast cancer is one of the leading causes of cancer-related mortality among women above 50 years of age. This systematic review and meta-analysis aimed at identifying the prevalence and trend of breast cancer screening among selected Asian countries.

METHODS

We searched three databases including, PubMed, Web of Science, and Scopus using our search terms. Two independent reviewers screened titles and abstracts applying the inclusion and exclusion criteria specified in the PROSPERO (registration ID: CRD42023401516) and any conflicts were resolved through discussion. Two independent reviewers and conflicts also completed the full-text screening, which was solved. Relevant information was extracted in an Excel sheet and random effects meta-analysis was performed to identify the pooled estimate of breast cancer screening in Asia using Stata 17.

RESULTS

We identified 41 studies from 14 selected Asian countries reporting breast cancer screening rates from 2012-2023. The pooled estimate of four countries (China, Iran, Japan, and Korea) with more than three data points on clinical breast examination and mammographic screening showed a screening rate of 24% (95% CI: 0.20 - 0.27) and 18% (95% CI: (0.14 - 0.21) in the last ten years respectively.

CONCLUSION

Most Asian countries do not have sufficient data on breast cancer screening due to a lack of nationally representative surveys or national-level cancer registries. Therefore, it is crucial to strengthen cancer control policies including breast cancer screening programs.

Pan-Asian adapted ESMO Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with early breast cancer

The European Society for Medical Oncology (ESMO) Clinical Practice Guidelines for the diagnosis, treatment and follow-up of patients with early breast cancer were updated and published online in 2023, and adapted, according to previously established standard methodology, to produce the Pan-Asian adapted (PAGA) ESMO consensus guidelines for the management of Asian patients with early breast cancer. The adapted guidelines presented in this manuscript represent the consensus opinions reached by a panel of Asian experts in the treatment of patients with breast cancer representing the oncological societies of China (CSCO), Indonesia (ISHMO), India (ISMPO), Japan (JSMO), Korea (KSMO), Malaysia (MOS), the Philippines (PSMO), Singapore (SSO), Taiwan (TOS) and Thailand (TSCO), co-ordinated by ESMO and KSMO. The voting was based on scientific evidence and was independent of the current treatment practices, drug access restrictions and reimbursement decisions in the different Asian regions represented by the 10 oncological societies. The latter are discussed separately in the manuscript. The aim is to provide guidance for the optimisation and harmonisation of the management of patients with early breast cancer across the different regions of Asia, drawing on the evidence provided by both Western and Asian trials, whilst respecting the differences in screening practices, molecular profiling, as well as the age and stage at presentation. Attention is drawn to the disparity in the drug approvals and reimbursement strategies, between the different regions of Asia.

A prognostic nomogram for predicting breast cancer survival based on mammography and AJCC staging

Rationale and objectives

To develop a prognostic nomogram using mammography data and AJCC staging to predict breast cancer survival.

Materials and methods

A prognostic nomogram was created using data from 1000 women diagnosed with breast cancer at a medical cancer center in Taiwan between 2011 and 2015. The variables included age at diagnosis (≤60 or > 60 years), mammography purpose (screening or diagnostic), mammography modality (digital mammogram or digital breast tomosynthesis), and the 7th American Joint Committee on Cancer (AJCC) stage. The outcome predicted was breast cancer-related mortality. The nomogram utilized Kaplan-Meier analysis for all subsets and Cox proportional hazards regression analysis for prediction. The nomogram's accuracy was internally validated using the concordance index and receiver operating characteristic (ROC) curve analysis, focusing on 3-year and 5-year survival predictions.

Results

Participants' mean age at breast cancer diagnosis was 54 years (SD = 11.2 years). The 1-year, 3-year, and 5-year overall survival (OS) rates were found to be 99.7%, 95.3%, and 91.4%, respectively. The bootstrap-corrected concordance indices indicated the following: nomogram, 0.807 and AJCC, 0.759. A significant difference was observed between the nomogram's area under the curve (AUC) and the AJCC stage in predicting the probability of 5-year survival (p = 0.005). A nomogram, constructed based on mammography and AJCC, demonstrated excellent calibration through internal validation using bootstrapping.

Conclusion

The utilization of a nomogram that incorporates mammography data and the AJCC registry data has been demonstrated to be a reliable predictor of breast cancer survival.

Barriers and enablers of breast cancer screening among women in East Africa: a systematic review

BACKGROUND

Breast cancer is among the most common cancers globally with a projected increase in incidence and mortality in low- and middle-income countries. The majority of the patients in East Africa present with advanced disease contributing to poor disease outcomes. Breast cancer screening enables earlier detection of the disease and therefore reduces the poor outcomes associated with the disease. This study aims to identify and synthesize the reported barriers and enablers of breast cancer screening among East African women.

METHODS

Medline, Embase, SCOPUS, and Cochrane library were searched for articles published on the subject from start to March 2022 using PRISMA guidelines. Also, forward citation, manual search of references and searching of relevant journals were done. A thematic synthesis was carried out on the "results/findings" sections of the identified qualitative papers followed by a multi-source synthesis with quantitative findings.

RESULTS

Of 4560 records identified, 51 were included in the review (5 qualitative and 46 quantitative), representing 33,523 women. Thematic synthesis identified two major themes - "Should I participate in breast cancer screening?" and "Is breast cancer screening worth it?". Knowledge of breast cancer and breast cancer screening among women was identified as the most influencing factor.

CONCLUSION

This review provides a rich description of factors influencing uptake of breast cancer screening among East African women. Findings from this review suggest that improving knowledge and awareness among both the public and providers may be the most effective strategy to improve breast cancer screening in Eastern Africa.

Family history and breast cancer risk for Asian women: a systematic review and meta-analysis

BACKGROUND

Studies of women of European ancestry have shown that the average familial relative risk for first-degree relatives of women with breast cancer is approximately twofold, but little is known for Asian women. We aimed to provide evidence for the association between family history and breast cancer risk for Asian women by systematically reviewing published literature.

METHODS

Studies reporting the familial relative risk of breast cancer for Asian women were searched in three online databases and complemented by a manual search. Odds ratios (ORs) for the association between family history and breast cancer risk were pooled across all included studies and by subgroups in terms of the type of family history, age, menopausal status and geographical region.

RESULTS

The pooled OR for women who have a first-degree relative with breast cancer was 2.46 (95% confidence interval [CI]: 2.03, 2.97). There was no evidence that the familial risk differed by the type of affected relative (mother versus sisters), the woman's age (< 50 years versus ≥ 50 years), menopausal status (pre versus post) and geographical region (East and Southeast Asia versus other regions) (all P > 0.3). The pooled ORs for women of Asian ancestry with a family history in any relative were similar for those living in non-Asian countries (2.26, 95% CI: 1.42, 3.59) compared with those living in Asian countries (2.18, 95% CI: 1.85, 2.58).

CONCLUSIONS

Family history of breast cancer is associated with an approximately twofold relative risk of breast cancer for Asian women, which is of similar magnitude to that observed for women of European ancestry. This implies that similar familial factors are implicated in breast cancer risk between women of European and Asian ancestries. Genetic factors are likely to play a substantial role in explaining the breast cancer familial risk for Asian women, as similar risks were observed across different living environments and cultures.

Barriers to breast and cervical cancer screening uptake among Black, Asian, and Minority Ethnic women in the United Kingdom: evidence from a mixed-methods systematic review

BACKGROUND

Cancer is currently the leading cause of mortality globally, with new cancer cases estimated at 19.3 million and almost 10 million deaths in 2020. Specifically, breast and cervical cancer incidence and mortality prevalence among women of the minority group or marginalised populations in Europe have continued to be a public health concern due to the low uptake of cancer screening. Thus, this study utilised a mixed-method systematic review to identify barriers to breast and cervical screening uptake among Black, Asian, and Minority Ethnic women in the United Kingdom.

METHODS

Databases including PubMed, CINAHL, British Nursing Index, Web of Science, EMBASE, and Scopus databases, were systematically searched for studies on barriers to breast and cervical screening uptake among Black, Asian, and Minority Ethnic women in the United Kingdom published in English between January 2010 to July 2022. This mixed-method systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in reporting the included studies' results. The cluster mapping approach was used to identify and classify the barriers into themes.

RESULTS

Thirteen eligible studies were included in this current review. Seven of the thirteen studies used quantitative cross-sectional research design, while six used qualitative cross-sectional research design. These studies were conducted across the United Kingdom. Five themes were developed from the cluster mapping, and thirty-four sub-theme barriers to the uptake of breast and cervical cancer screening among Black, Asian, and Minority Ethnic women in the United Kingdom were identified. The developed themes in relation to the barriers include; socio-demographic characteristics, health service delivery, cultural, religious & language, the gap in knowledge & awareness, and emotional, sexual & family support.

CONCLUSION

The study concluded that barriers in socio-demographic characteristics, health service delivery, cultural, religious and language, the gap in knowledge & awareness, and emotional, sexual & family support were identified as non-uptake of breast and cervical cancer screening among Black, Asian, and Minority Ethnic women in the United Kingdom. Reducing or eliminating these barriers would improve the benefits of timely breast and cervical cancer screening in the United Kingdom.

Temporal trends of cervical cancer between 1990 and 2019, in Asian countries by geographical region and socio-demographic index, and comparison with global data

Objectives

Cervical cancer is the fourth most common cancer in women and one of the most important health challenges in the world. Although the epidemiological statistics of cervical cancer seem to be varied in Asia, no study has evaluated the trend of this disease and the changes in its incidence and epidemiology in recent decades. Therefore, this study was conducted to determine the temporal trend of cervical cancer between 1990 and 2019 in Asian countries based on geographic region and socio-demographic index (SDI), and also compare it with global data.

Methods

We collected cervical cancer data from the 2019 Global Burden of Disease (GBD) study from 1990 to 2019 in 49 Asian countries and territories. In this study, data were extracted in different classifications of Asian countries based on an SDI, and five GBD categories for Asian countries from 1990 to 2019 and compared with global data. Data were reported in values with a confidence interval (CI) of 95%. We used relative difference (%) between years to show the comparative changes in incidences, prevalence, deaths, and disability-adjusted life years (DALY) age-standardized rates. Average annual percentage change (AAPC) and its 95% CI in the 30-year past period for each location were calculated by using age-standardized rates (ASR) and with Joinpoint version 4.9.1.0 software.

Results

In Asia, the number of cervical cancer incidences, prevalence, death, and DALYs increased to 1.94, 2.26, 1.7, and 1.5-fold, respectively; while globally, these numbers increased by 1.67, 1.89, 1.52, and 1.45 times, respectively. In Asia, the AAPC of cervical cancer age-standardized incidence rate (ASIR), age-standardized prevalence rate (ASPR), the age-standardized death rate (ASDR), and DALYs age-standardized rates (DALYs ASRs) were −0.3, 0.5, −1.0, and −1.0 respectively. The AAPC of these indicators worldwide was −0.4, 0.2, −0.9, and −0.9, respectively. South Asia and Southeast Asia experienced the highest decrease in ASIR of cervical cancer from 1990 to 2019. In 2019, all GBD regions of Asia experienced a decreasing trend in ASDR and DALYs ASRs of cervical cancer. In 2019, the highest ASIR, ASPR, ASDR, and DALYs ASR of cervical cancer belonged to Brunei Darussalam, Brunei Darussalam, Mongolia, and Mongolia, respectively, and the lowest in all above categories was related to the Syrian Arab Republic, Syrian Arab Republic, Kuwait, and Kuwait; respectively.

Conclusions

Although the epidemiological statistics of cervical cancer in Asia have started to decline, this disease is still one of the most important causes of death for women in this region. So it seems in addition to improving screening coverage and management, we need to implementation of educational and awareness-raising interventions regarding cervical cancer, eliminate misconceptions related to testing results, and emphasize the preventable nature of this cancer by early detection using screening methods.

Breast Cancer in Asia: Incidence, Mortality, Early Detection, Mammography Programs, and Risk-Based Screening Initiatives

Close to half (45.4%) of the 2.3 million breast cancers (BC) diagnosed in 2020 were from Asia. While the burden of breast cancer has been examined at the level of broad geographic regions, literature on more in-depth coverage of the individual countries and subregions of the Asian continent is lacking. This narrative review examines the breast cancer burden in 47 Asian countries. Breast cancer screening guidelines and risk-based screening initiatives are discussed.

Factors influencing participation in preventive interventions for gastric cancer: the results from the GISTAR study

OBJECTIVES

Search-and-treat strategy for Helicobacter pylori and surveillance of patients with precancerous lesions are recommended to decrease the burden of gastric cancer in high-risk areas. We aimed to evaluate the acceptance of the target population to these strategies.

METHODS

We applied a search-and-treat strategy combined with biomarker screening (pepsinogens I and II, gastrin-17) for atrophic gastritis to healthy individuals aged 40-64 years within the GISTAR Pilot study. Different means of invitation were evaluated - direct telephone calls, letters of invitation via the general practitioners. Participants with altered biomarker results were invited to undergo upper gastrointestinal endoscopy. H.pylori positive individuals were offered eradication therapy. Data on the compliance to the treatment and reasons for noncompliance were collected via telephone.

RESULTS

Altogether 3453 participants were enrolled. The attendance of women participants was 1.9 times higher although active invitation strategies were mainly targeting men. The yield for the telephone invitations was higher than for mail-delivered invitations (2.1 calls vs. 7.7 letters required to recruit one study subject). Out of 661 individuals reached with the invitation to undergo upper endoscopy, 520 (78.7%) attended the procedure. Out of 1185 study subjects eligible for eradication, 810 (68.4%) accepted it. Of those having received the medication, 765(94.4%) completed it. The reasons for nonparticipation were the overall misconception of the importance of screening, busy schedule and others.

CONCLUSIONS

While only the minority of the target population participated in the gastric cancer prevention strategy, relatively high compliance was seen among the participants. The acceptance rate and the identified reasons for refusing to participate in our study indicate that there is a need to raise gastric cancer awareness and its existent preventive strategies within the general population for their successful implementation in the community.

Determinants of Intention to Participate in Breast Cancer Screening among Urban Chinese Women: An Application of the Protection Motivation Theory

Despite the significance of early detection of breast cancer through screening, the screening uptake in China remains relatively low. Protection motivation theory (PMT) suggested by Rogers is one of the theories concerning threat appeal. This study aimed to apply the protection motivation theory (PMT) in predicting breast cancer screening intention. In this cross-sectional study, a sample of Chinese urban women was recruited using the convenient sampling method from five communities in Wuhan. Data were collected using a self-report questionnaire that included demographic variables, knowledge about breast cancer, six PMT subconstructs, and screening intention. We used the structural equation modeling (SEM) to identify the predictor factors associated with screening intention. Of the total sample (n = 412), 86.65% had intention to participate in screening. Our data fit the hypothesized SEM model well (Goodness of fit index (GFI) = 0.91, adjusted GFI (AGFI) = 0.89, comparative fit index (CFI) = 0.91, root mean square error of approximation (RMSEA) = 0.05, standardized root mean residual (SRMR) = 0.06, and Chi-square/df = 2.01). Three PMT subconstructs (perceived severity, response cost, and self-efficacy) were significantly associated with screening intention. Knowledge, social status, and medical history had significantly indirect associations with screening intention through the mediating effect of PMT subconstructs. Considering the utility of PMT, intervention programs might be more effective based on the subconstructs of PMT, especially to improve self-efficacy, perceived severity, and knowledge, reduce response cost, as well as targeting specific demographic groups.

The Barriers and Facilitators of Gastric Cancer Screening: a Systematic Review

AIM

Gastric cancer is the third leading cause of cancer death and the fifth most common cancer worldwide. Screening is one of the most important ways to increase survival. The aim of this systematic review was to determinate barriers and facilitators for accessing gastric cancer screening.

MATERIALS AND METHODS

In this systematic review, for identifying barriers and facilitators of gastric cancer screening, a comprehensive search was conducted in electronic databases such as PubMed, Web of Science, and Scopus in 2021. Combination keywords such as gastric cancer, screening, endoscopy, barriers, and facilitators were used for searching. Full text original studies in English language that are dealing with barriers and facilitators for accessing gastric cancer screening were included in this review.

RESULTS

A total 13 articles included in this review. Ten barriers and ten facilitators were evaluated. The most common reported barriers were lack of signs, fear of screening procedure, fear of screening outcome, cost of screening, and embarrassment. The most frequent facilitator was socio demographic factors such as age, education, and employment.

CONCLUSION

For promoting success in gastric cancer, screening programs, knowing barriers, and facilitators is  necessary. No signs and symptoms of disease have been shown as the major barriers toward gastric cancer screening in most studies.
