Thus the present study aimed to assess the levels of knowledge towards hormonal related breast cancer risk factors in Qurayyat, Northern Saudi Arabia. Methodology: This descriptive study in- cluded 737 Saudi volunteers living in the city of Qurayyat, Northern Saudi Arabia. For females, only those agreeing to participate in the breast self-examination workshop were included, and non-respondents were in- cluded in the questionnaire. Results: For the question apropos “Inheritance as a risk factor for BC,” 405/607 (66.7%) females signposted certainly “Yes,” as well as, 70/130 (54%) males signposted certainly “Yes.” The odds ratio (OR) and 95% confidence interval (95% CI) were not statistically significant, but the level of knowledge was relatively higher among females OR (95% CI) = 1.4321 (0.9597 to 2.1370), P = 0.0786. “Are early puberty and late meno- pause risk factors for breast cancer?” No statistical significant differences were eminent between males and females, OR (95% CI) = 0.8878 (0.5932 to 1.3287), P = 0.5629. Conclusion: Saudi women are enthusiastically willing to raise their knowledge and awareness of breast cancer prevention and control. Although women have greater knowledge about breast cancer risk factors compared to men, still some gaps need to be filled.
