Therefore, the aim of this study was to determine breast cancer related awareness and approach toward exposure to diverse patterns of hormones among women in Northern Saudi Arabia. Methodology: This is a cross sectional survey included 400 Saudi females' volunteers living in the city of Hail, Northern Saudi Arabia. Knowledge, awareness and approach toward exposure to diverse patterns of hormones and breast cancer risk were evaluated using different variables during interview. Results: On asking the participants the question 'Does the over exposure to hormones (ER) increases the risk of breast cancer' Out of 387 respondents, 47.5% answered yes increases the risk of breast cancer. On asking the participants the question 'Does early puberty and late menopause increase the risk of breast cancer' Out of 395 respondents, 35.2% answered yes increases the risk of breast cancer. Conclusion: Knowledge of hormonal breast cancer risk factors is not so strong so as to achieve the intended values in Northern Saudi Arabia. Knowledge of breast cancer risk factors can powerfully participate to the breast cancer prevention struggles, which will have the chief results mainly if started at an early age and continued over a lifetime. http://pubs.sciepub.com/ajcp/5/4/1/ajcp-5-4-1.pdf breast cancer Awareness risk factors hormones Saudi Arabia
