Abstract
Background Breast cancer is the most common of all female cancers worldwide. A large percentage are diagnosed at a late stage, which can be related to awareness and knowledge deficiency. We aimed to assess the level of knowledge of and attitude to breast cancer and breast self-examination in Jeddah, Saudi Arabia. Methodology A descriptive cross-sectional study was carried out among 392 women in Jeddah, Saudi Arabia. Using a non-probability sampling technique, a self-administered validated questionnaire was distributed via social media. Inclusion criteria were ages above 18 years old of all educational levels. Results Out of 392 participants, there were 146 in the age group of 19-25 (37.2%). Most of the participants are aware of breast cancer (94.9%). The mean knowledge score was 6.9 ± 3.36. Ninety-two percent (92%) of participants had poor knowledge. Most respondents reported that the main risk factor for breast cancer was family history (83.7%). About 37% believed that the purpose of the breast self-examination practice is advice from a health care professional followed by routine examination (37.3%). About 97% agreed that early detection of breast cancer increases the chance of recovery. Conclusion There is a lack of knowledge and awareness about the risk factors and symptoms of breast cancer. Despite a positive attitude toward breast self-examination, it is poorly practiced.
