Lack of awareness about breast cancer and its screening in developing countries

"So, when a woman becomes ill, the total structure of the family is affected, they can't do anything…" Voices from the community on women with breast cancer in India: a qualitative focus group study

Background

Psychological symptoms are common in women with breast cancer and profoundly affect their role in the family and wider community, varying across cultural backgrounds. Breast cancer is becoming the most common cancer among women in India. We aimed to understand the cultural context within which Indian women with breast cancer living in India, experience psychological concerns from the perspectives of healthcare professionals, volunteers and church members.

Methods

Five focus groups were conducted in South India (clinicians (2 groups)) lay public (3 groups). A topic guide was explored: understanding of breast cancer, experiences of patients with regard to diagnosis and treatment and psychological impact. Groups were audio-recorded and verbatim transcribed. Lay groups were conducted in Malayalam with translation and back-translation. Transcripts were subjected to thematic analysis using “cultural task analysis” as a lens for analysis.

Results

Forty-five (oncologists (5), nurses (10), church members (16) and community volunteers working in a palliative care unit (14) participated. Three major themes psychosocial issues related to diagnosis, psychosocial impact of cancer treatment and coping with diagnosis and treatment and nine subthemes emerged from the two groups. All described psychological impact on women with breast cancer including body image, change of family role and their need for support. Family and faith were recognised as the major framework providing key support but also significant stress. Clinicians were also concerned about financial implications and issues around early cancer detection. Laypeople and nurses also commented that poor communication and lack of empathy from doctors aggravated distress.

Conclusion

Clinical and lay communities were aware of the widespread psychological impact affecting women with breast cancer which are amplified by the patriarchal context within which they live, which extends into clinical practice. Family and faith provide a strong support structure and are a cause of distress, as core roles and expectations are challenged by this disease of womanhood.

Breast Self-Examination Practice Among Female University Students in Ethiopia: A Systematic Review and Meta-Analysis

Background:

Breast self-examination (BSE) is one of the most feasible methods of screening for early stages of breast cancer. However, the practice rate is insufficient in many low and middle-income countries including Ethiopia. Hence, this study aimed to estimate the pooled prevalence of BSE practice among female university students in Ethiopia.

Methods:

PubMed, Cochrane Library, Scopus, and Google Scholar were searched for studies that assessed BSE practice among female students in Ethiopian universities. The study included articles published from January 1st, 2010 to June 16th, 2020. The Cochran’s Q chi-square and the respective I² test statistics were used to check heterogeneity among the included studies. To assess publication biases, the funnel plot and Egger’s regression tests were employed. Subgroup analysis was done by using different characteristics of studies. Sensitivity analysis was also run to assess the effect of a single study on the pooled outcome. STATA™ Version 14 software packages were employed for data analysis.

Results:

Sixteen (n = 16) studies with 5,743 participants were included to estimate the pooled prevalence of BSE practice. The prevalence of regular BSE practice reported in the studies ranges from 0% to 26.4%. The estimated pooled prevalence of regular BSE practice among university students in Ethiopia is 11.23% which is very low. The prevalence of BSE practice was high, 13.6% in studies published before 2015, 12.0% among health science students, and 12.6% in studies with a sample size of 384 participants and above. In addition, the estimated pooled prevalence of irregular self-breast-examination practice was 33.28%.

Conclusion:

The rate of BSE practice among female university students is low. Thus, awareness strategies need to be designed to increase the practice rate among women in the country as BSE is one of the most feasible strategies in early detection of breast cancer if properly implemented.

Barriers to mammography screening among racial and ethnic minority women

RATIONALE

Breast cancer is the second leading cause of cancer death among women. Disparities in breast cancer mortality rates adversely affect racial/ethnic minority women. Mammography screening is the most effective early detection method and means of reducing mortality rates. Yet, barriers prevent racial/ethnic minority women from participating in regular screening.

OBJECTIVE

This review aimed to summarize self-reported barriers to mammography screening in racial/ethnic minority women in studies using open-ended assessments and closed-ended assessments.

METHOD

Literature searches were conducted in two databases, PsycINFO and PubMed. Barriers were detailed in full by barrier type (psychological/knowledge-related, logistical, cultural/immigration-related, and social/interpersonal) and summarized briefly by race/ethnicity (African American/Black, Asian/Pacific Islander, Hispanic, American Indian/Native American, and Middle Eastern).

RESULTS

Twenty-two open-ended and six closed-ended studies were identified as eligible for this review. Overall, racial/ethnic minority women identified common logistical and psychological/knowledge-related barriers. Additionally, women reported cultural/immigration-related and social/interpersonal barriers that were closely tied to their racial/ethnic identities.

CONCLUSIONS

It was concluded that cultural/immigration-related barriers may be the only barrier type that is unique to racial/ethnic minority women. Thus, designing studies of barriers around race and ethnicity is not always appropriate, and other demographic factors are sometimes a more important focus. The variability in 'barrier' definitions, how data were collected and reported, and the appropriateness of closed-ended measures were also examined. This literature may benefit from detailed and strategically designed studies that allow more clear-cut conclusions and better comparison across studies as well as improving closed-ended measures by incorporating insights from investigations using open-ended inquiry.

The Situation of Cancer Treatment in Ethiopia: Challenges and Opportunities

Background

Less attention is given to cancer treatment and control in Ethiopia.

Methods

To investigate the challenges and opportunities facing cancer treatment services in Ethiopia. A purposive sampling technique was applied to recruit the study subjects from Black Lion Specialized Hospital Oncology Department. A semi-structured interview guide was used to investigate challenges and opportunities in oncology service in Ethiopia. Data was transcribed and coded by two independent coders and analyzed thematically in reference to the objectives.

Results

Fifteen professionals from four different disciplines were interviewed on opportunities and challenges facing cancer treatment in Ethiopia. Out of these respondents 3 were senior clinical oncologists while 4 individuals were senior oncology residents. The rest were 2 medical Physicists, 2 radiotherapy technologists and 4 oncology nurses. Majority (80%) of the respondents were males. We demonstrate that the challenges of cancer treatment service in Ethiopia emanate from the patients themselves, the administrating body, the professionals, and the technology limitations. In general, the result of this study was grouped under the following five themes: Customer-related challenges, provider-related challenges, facility-related challenges, technology-related challenges and the opportunities.

Conclusions

Several assignments are waiting for the policy makers, the professionals, the communities and other concerned bodies to combat the alarmingly growing burden of cancer in Ethiopia. Escalating the awareness of the general population about cancer, expanding well-developed diagnostic and treatment centers, and producing well-trained competent oncology professionals are the forefront challenges in combating cancer in Ethiopia.

Changing pattern in the clinical presentation of breast cancer in the absence of a screening program over a period of thirty-three years in Iran

OBJECTIVE

To survey the proportion of stages at the presentation of the disease without a screening program, among a population of breast cancer patients that is as a representative sample of the country in a distinct period.

MATERIALS AND METHODS

The population of the current study is found among the female breast cancer patients who were referred to oncology centers in northeastern Iran over a thirty-three-year period from 1980 to 2012.

RESULTS

Four thousand patients were divided into three time periods consisting of 521 cases from 1980 to 1990, 1178 cases from 1991 to 2001, and 2302 cases from 2002 to 2012. While there was no difference in the proportions of T1 and T3 tumors, T2 tumors showed an increase (P = 0.001) and T4 tumors a decrease (P = 0.000) during these periods. There was no change in the proportion of stage I, however the proportion of stage II had risen (P = 0.000), while that of stage III (P = 0.002), and stage IV (P = 0.000) had fallen. The study's urban and rural populations experienced a similar trend in this respect, with the exception that the rural population exhibited more striking changes during the study's recent years.

CONCLUSION

After a thirty-three-year follow up on breast cancer in northeastern Iran, it is obvious that this disease is now presented in its earlier stages even in the absence of a screening program. In spite of this, the proportion of T1 disease and those tumors are discovered by a screening program has not significantly changed.

Understanding breast health awareness in an Arabic culture: qualitative study protocol

AIM

To explore breast health awareness and the early diagnosis and detection methods of breast cancer from the perspective of women and primary healthcare providers in the Jizan region of the Kingdom of Saudi Arabia.

BACKGROUND

Although there is a high incidence of advanced breast cancer in young women in the Kingdom of Saudi Arabia, there is no standardized information about breast self-examination, or is there a national screening programme involving clinical breast examination and mammography available.

DESIGN

Qualitative exploratory study.

METHODS

Data collection will consist of 36 face-to-face semi-structured interviews: 12 with general practitioners; 12 with nurses at primary healthcare centres and with 12 women who attend the health centres. This study will be carried out in eight states across the Jizan region (four rural and four urban) to reflect the cultural diversity of Jizan. The data will be analysed using thematic content analysis. Research Ethics Committee approval was obtained in June 2015.

DISCUSSION

While we understand the enablers and barriers to breast health awareness outside of Saudi culture, in the Kingdom of Saudi Arabia, particularly in rural populations such as Jizan, there is a lack of research. This study will add positively to the international knowledge base of this topic. The findings will give evidence and inform policy about women and healthcare providers' experiences in Jizan, in a society where such topics are taboo.

Study of microRNAs-21/221 as potential breast cancer biomarkers in Egyptian women

microRNAs (miRNAs) play an important role in cancer prognosis. They are small molecules, approximately 17-25 nucleotides in length, and their high stability in human serum supports their use as novel diagnostic biomarkers of cancer and other pathological conditions. In this study, we analyzed the expression patterns of miR-21 and miR-221 in the serum from a total of 100 Egyptian female subjects with breast cancer, fibroadenoma, and healthy control subjects. Using microarray-based expression profiling followed by real-time polymerase chain reaction validation, we compared the levels of the two circulating miRNAs in the serum of patients with breast cancer (n=50), fibroadenoma (n=25), and healthy controls (n=25). The miRNA SNORD68 was chosen as the housekeeping endogenous control. We found that the serum levels of miR-21 and miR-221 were significantly overexpressed in breast cancer patients compared to normal controls and fibroadenoma patients. Receiver Operating Characteristic (ROC) curve analysis revealed that miR-21 has greater potential in discriminating between breast cancer patients and the control group, while miR-221 has greater potential in discriminating between breast cancer and fibroadenoma patients. Classification models using k-Nearest Neighbor (kNN), Naïve Bayes (NB), and Random Forests (RF) were developed using expression levels of both miR-21 and miR-221. Best classification performance was achieved by NB Classification models, reaching 91% of correct classification. Furthermore, relative miR-221 expression was associated with histological tumor grades. Therefore, it may be concluded that both miR-21 and miR-221 can be used to differentiate between breast cancer patients and healthy controls, but that the diagnostic accuracy of serum miR-21 is superior to miR-221 for breast cancer prediction. miR-221 has more diagnostic power in discriminating between breast cancer and fibroadenoma patients. The overexpression of miR-221 has been associated with the breast cancer grade. We also demonstrated that the combined expression of miR-21 and miR-221can be successfully applied as breast cancer biomarkers.

Preventing breast cancer in LMICs via screening and/or early detection: The real and the surreal

To review the present status of breast cancer (BC) screening/early detection in low- and middle-income countries (LMICs) and identify the way forward, an open focused search for articles was undertaken in PubMed, Google Scholar and Google, and using a snowball technique, further articles were obtained from the reference list of initial search results. In addition, a query was put up on ResearchGate to obtain more references and find out the general opinion of experts on the topic. Experts were also personally contacted for their opinion. Breast cancer (BC) is the most common cancer in women in the world. The rise in incidence is highest in LMICs where the incidence has often been much lower than high-income countries. In spite of more women dying of cancer than pregnancy or childbirth related causes in LMICs, most of the focus and resources are devoted to maternal health. Also, the majority of women in LMICs present at late stages to a hospital to initiate treatment. A number of trials have been conducted in various LMICs regarding the use of clinical breast examination and mammography in various combinations to understand the best ways of implementing a population level screening/early detection of BC; nevertheless, more research in this area is badly needed for different LMIC specific contexts. Notably, very few LMICs have national level programs for BC prevention via screening/early detection and even stage reduction is not on the public health agenda. This is in addition to other barriers such as lack of awareness among women regarding BC and the presence of stigma, inappropriate attitudes and lack of following proper screening behavior, such as conducting breast self-examinations. The above is mixed with the apathy and lack of awareness of policy makers regarding the fact that BC prevention is much more cost-effective and humane than BC treatment. Implementation of population level programs for screening/early detection of BC, along with use of ways to improve awareness of women regarding BC, can prove critical in stemming the increasing burden of BC in LMICs. Use of newer modalities such as ultrasonography which is more suited to LMIC populations and use of mHealth for awareness creation and increasing screening compliance are much needed extra additions to the overall agenda of LMICs in preventing BC.

Breast cancer knowledge and related behaviors among women in Abha City, southwestern Saudi Arabia

Breast cancer is the most common malignancy among women in Saudi Arabia. A cross-sectional study was conducted on 1,092 women attending urban primary health care centers in Abha City southwestern Saudi Arabia about breast cancer knowledge, attitudes, and related practices. Only 22.0% heard about mammography, and 41.5% heard about breast self-examination (BSE). More than half of the women in the study identified changes occurring in case of breast cancer and identified risk factors. Only 8.3% were examined by clinical breast examination (CBE), 6.2% were examined by mammography, and 29.7% performed BSE. The study points to the insufficient knowledge of women and the low practice of BSE, CBE, and mammography. Public awareness should be enhanced by all available means including mass media, schools, social gatherings, and waiting areas in primary health care centers. There is an urgent need for continuing medical education programs for health care workers in the region concerning breast cancer.

Systematic review of breast cancer biology in developing countries (part 1): Africa, the middle East, eastern europe, Mexico, the Caribbean and South america

There has been no systematic appraisal of ethnicity-based variations in breast cancer (BC) biology amongst women from developing countries. A qualitative systematic review was conducted of breast cancer size, stage, grade, histological type, extra-mammary involvement, hormone receptor status as well as patient demographics. This review includes patients from Africa, the Middle East, Eastern Europe, Mexico, the Caribbean and South America. BC in these regions present at an earlier age with large aggressive tumours. Distant metastases are frequently present at the time of diagnosis. African women have a higher frequency of triple negative tumours. Over half of Middle Eastern women have lymph node involvement at the time of diagnosis. Despite experiencing a lower incidence compared to the Ashkenazi Jewish population, Palestinian women have poorer five-year survival outcomes. The majority of women from Mexico and South America have stage two or three disease whilst over sixty percent of women from Eastern Europe have either stage one or stage two disease. The biological characteristics of BC in the Caribbean cannot be fully assessed due to a paucity of data from the region. BC amongst the developing world is characterised by an early peak age of onset with aggressive biological characteristics. Strategies that improve breast cancer awareness, address amenable risk factors and improve early detection are essential.

Breast cancer in low- and middle-income countries: an emerging and challenging epidemic

Breast cancer is a major health care problem that affects more than one million women yearly. While it is traditionally thought of as a disease of the industrialized world, around 45% of breast cancer cases and 55% of breast cancer deaths occur in low and middle income countries. Managing breast cancer in low income countries poses a different set of challenges including access to screening, stage at presentation, adequacy of management and availability of therapeutic interventions. In this paper, we will review the challenges faced in the management of breast cancer in low and middle income countries.

Improving Breast Cancer Control via the Use of Community Health Workers in South Africa: A Critical Review

Breast cancer is a growing concern in low- and middle-income countries (LMCs). We explore community health worker (CHW) programs and describe their potential use in LMCs. We use South Africa as an example of how CHWs could improve access to breast health care because of its middle-income status, existing cancer centers, and history of CHW programs. CHWs could assume three main roles along the cancer control continuum: health education, screening, and patient navigation. By raising awareness about breast cancer through education, women are more likely to undergo screening. Many more women can be screened resulting in earlier-stage disease if CHWs are trained to perform clinical breast exams. As patient navigators, CHWs can guide women through the screening and treatment process. It is suggested that these roles be combined within existing CHW programs to maximize resources and improve breast cancer outcomes in LMCs.
