Awareness and Risk Assessment of Breast Cancer Among Women in Saudi Arabia: A Cross-Sectional Study

Background Breast cancer is the most common female cancer worldwide including in Saudi Arabia. As a result, many cases are diagnosed at an advanced stage, leading to a poor outcome. Understanding risk perception is a significant component of awareness of breast cancer risks. It can be helpful to reduce the mortality of breast cancer via increasing awareness of the risk factors. Objective Our study was designed to assess the level of awareness among women in Saudi Arabia regarding breast cancer, including knowledge about risk factors, symptoms, and the importance of early detection. Methods A cross-sectional study was conducted, and participants were randomly selected. The target population in this study is all women in Saudi Arabia. Data was collected via an online questionnaire. The collected data was analyzed using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 21.0, Armonk, NY). Results About 713 women were enrolled in this study. Most of them (69%) were within the age group of 35-45 years old. Age at menarche was found to be 12-13 years old in 313 (43.9%) of the participants and age at first live birth was found to be 20-24 in about 360 (50.5%). The number of population with first-degree relatives that have a history of breast cancer is one relative in 126 (17.7%) of the participants and about 36 (5%) had breast biopsy. About 76 (10.7%) of the participants were considered as having a high risk of breast cancer according to the estimated five-year breast cancer-risk assessment (had a five-year breast cancer risk >1.66%). The mean knowledge score of the participants about breast cancer was found to be 4.62 ± 1.86 out of 8. About 509 (71.4%) of the participants were considered to be having a good level of knowledge about breast cancer. Long-term hormone contraceptive use and older age can increase the chance of developing breast cancer as agreed on by 363 (50.9%) and 287 (40.3%) of the participants respectively. A total of 677 (95%) of the participants mentioned that early detection is important to survive breast cancer. And 639 (89.6%) of the participants think that breast cancer is treatable and about 288 (40.4%) think that the suitable age to start mammography is above 30 years old. Conclusion There is a good general knowledge and awareness about breast cancer among study participants. There were few knowledge gaps regarding the effect of obesity, hormonal contraceptives and older age on the association with breast cancer. About 10% of the participants were found to be having high five-year breast cancer risk.
