Knowledge and Perceptions of Common Breast Cancer Risk Factors in Northern Saudi Arabia

Women's Knowledge and Attitudes Regarding the Risk Factors and Warning Signs of Breast Cancer in the Eastern Province, Saudi Arabia: A Cross-Sectional Study

Introduction Breast cancer is the leading type of cancer in women globally, contributing significantly to cancer-related deaths. In Saudi Arabia, it ranks as the second most common cancer among women. Studies have highlighted a lack of awareness about breast cancer, negatively impacting breast self-examination practices. The Eastern Province has particularly high incidence rates. Knowledge of risk and protective factors can aid in prevention and early detection. While some studies show good awareness, this research aims to assess women's knowledge and attitudes about breast cancer risk factors and warning signs in the Eastern Province. Methodology This is a cross-sectional study conducted in Saudi Arabia's Eastern Province from June to October 2023 to assess breast cancer awareness among adult females. Data were collected via an online survey. Data were cleaned in MS Excel (Microsoft Corporation, Redmond, Washington) and analyzed in IBM SPSS Statistics for Windows, Version 23 (Released 2015; IBM Corp., Armonk, New York). Results Our study assessed breast cancer awareness in 697 participants in Saudi Arabia's Eastern Province. Most were aged 20-24 years (30.3%), married (49.2%), and Saudi nationals (97.6%), with higher education (59.4%). Significantly, 69.2% received education on breast cancer risk factors/signs. Some had personal breast cancer diagnoses (5.0%), and 31.7% had affected family members. Participants showed good awareness of various risk factors and warning signs. Significant associations were found between nationality, personal breast cancer diagnosis, and knowledge and attitudes about risk factors. Age, marital status, occupation, education on breast cancer, and personal breast cancer diagnosis influenced knowledge and attitudes about warning signs. Conclusion Our study findings indicate generally good awareness of breast cancer risk factors and warning signs among participants. Age, marital status, occupation, education on breast cancer, and personal breast cancer diagnosis influenced knowledge and attitudes about risk factors and warning signs. Educational efforts should target lesser-known risk factors to enhance prevention and early detection.

Using the Health Belief Model to Predict the Uptake of Mammographic Screening Among Saudi Women

Background

Breast cancer (BC) is known to be the second leading cause of cancer deaths after lung cancer in Saudi Arabia. Early detection using screening methods can improve disease outcomes. In Saudi Arabia, the rates of BC screening are very low although it is a country that provides free healthcare services. This discrepancy between the availability of free healthcare services and women not utilizing these services necessitates an in-depth understanding of the health-related beliefs and barriers towards BC screening among Saudi women. 

Objective

We aimed to use the Health Belief Model (HBM) to predict the uptake of mammographic screening among Saudi women. The secondary objective was to determine the knowledge, attitudes, and practices related to BC and mammography screening.

Research methodology 

This was an analytical cross-sectional study using a self-administered questionnaire, which consisted of sociodemographic data, family history of BC, general information about BC, and the Champion’s Health Belief Model Scale (CHBMS). The study was conducted among Saudi women visiting the King Khalid University Hospital in Riyadh from September 2018 to February 2019. The data were analyzed using SPSS Statistics software version 26.00 (IBM, Armonk, NY).

Results

A total of 401 females participated in the study; the median age of the subjects was 49 years [interquartile range (IQR): 43-53 years]. Among them, 69.6% were married and 21.1% had a family history of BC. There was a statistically significant association of younger age, marital status, and a positive family history of BC with women undergoing mammographic screening (p<0.05).

Of the participants, 61.6% knew about the warning signs of BC, while only 59.9% were aware of the risk factors associated with it. The binary logistic regression did not show any significant association between CHBMS and mammogram screening. We concluded that the CHBMS components cannot be used in isolation to predict the risk of not undergoing mammogram screening. However, barriers and motivation components along with the knowledge and other factors can be used to predict mammogram screening.

Conclusion

Among our cohort of Saudi women, 62.1% had general awareness about BC, and younger age, marital status, and positive family history of BC were significantly associated with women undergoing mammography screening. The CHBMS components cannot be used in isolation to predict the risk of not undergoing mammogram screening, while barriers and motivation components along with the knowledge and other factors can be used to predict mammogram screening.

Psychosocial Aspects of Female Breast Cancer in the Middle East and North Africa

Breast cancer, the most common cancer among women in the Middle East and North Africa (MENA) region, is associated with social and psychological implications deriving from women's socio-cultural contexts. Examining 74 articles published between 2007 and 2019, this literature/narrative review explores the psychosocial aspects of female breast cancer in the MENA region. It highlights socio-cultural barriers to seeking help and socio-political factors influencing women's experience with the disease. In 17 of 22 Arab countries, common findings emerge which derive from shared cultural values. Findings indicate that women lack knowledge of breast cancer screening (BCS) and breast cancer self-examination (BSE) benefits/techniques due to a lack of physicians' recommendations, fear, embarrassment, cultural beliefs, and a lack of formal and informal support systems. Women in rural areas or with low socioeconomic status further lack access to health services. Women with breast cancer, report low self-esteem due to gender dynamics and a tendency towards fatalism. Collaboration between mass media, health and education systems, and leading social-religious figures plays a major role in overcoming psychological and cultural barriers, including beliefs surrounding pain, fear, embarrassment, and modesty, particularly for women of lower socioeconomic status and women living in crises and conflict zones.

Comprehensive study for BRCA1 and BRCA2 entire coding regions in breast cancer

BACKGROUND

About 5-10% of incidences of breast cancers have been reported as a result of germline mutations of BRCA genes. However, the mutational spectrum of BRCA1 and BRCA2 genes among breast cancer Saudi women patients is inadequate at present. Therefore, the present study aimed to report the specific germinal mutation of BRCA1 and BRCA2 in the entire coding regions, to investigate the prevalence rate of BRCA1 & BRCA2 mutations among Saudi women and the effect of these mutations, both benign and malignant tumors.

METHODOLOGY

A total of 270 tissue samples of benign and malignant breast tumors were collected from Saudi women patients, Riyadh, Saudi Arabia. Examination of BRCA1 and BRCA2 germline mutations was performed using heteroduplex DNA analysis (HDA) or single-stranded conformation analysis (SSCA). 177 breast cancer women with malignant tumors and 93 with benign tumors were enrolled in the study. A total of 62 out of 177 breast cancer patients carried a BRCA1 or BRCA2 mutation (54 BRCA1 and 8 BRCA2). The analysis was done using the Sanger sequence assay.

RESULTS

Point and frameshift mutations through the entire coding area of the two genes indicated that all the mutations were germline alterations and of early-onset breast cancers. The mean ages of diagnosed breast cancer women for BRCA1 and BRCA2 mutation carriers were 36.3 (± 3.5) and 37.9 (± 3.7) years, whereas that of benign control was 35(± 2.5) years.

CONCLUSION

Point and frameshift mutations across the entire coding region of BRCA1 and BRCA2 are responsible for many breast cancers cases.
