The Breast Cancer Risk Assessment Tool is an interactive tool designed by scientists at the National Cancer Institute (NCI) and the National Surgical Adjuvant Breast and Bowel Project (NSABP) to estimate a woman's risk of developing invasive breast cancer. The tool has been updated for African American women based on the Contraceptive and Reproductive Experiences (CARE) Study, and for Asian and Pacific Islander women in the United States based on the Asian American Breast Cancer Study (AABCS). See About the Tool for more information.
Reminder: The Breast Cancer Risk Assessment Tool was designed for use by health professionals. If you are not a health professional, you are encouraged to discuss these results and your personal risk of breast cancer with your doctor.
Race/Ethnicity:
White
5 Year Risk
- This woman (age 50) 1.8%
- Average woman (age 50): 1.3%
Explanation
Based on the information provided (see below), the woman's estimated risk for developing invasive breast cancer over the next 5 years is 1.8% compared to a risk of 1.3% for a woman of the same age and race/ethnicity from the general U.S. population. This calculation also means that the woman's risk of NOT getting breast cancer over the next 5 years is 98.2%.
Lifetime Risk
- This woman (to age 90): 16.4%
- Average woman (to age 90): 11.2%
Explanation
Based on the information provided (see below), the woman's estimated risk for developing invasive breast cancer over her lifetime (to age 90) is 16.4% compared to a risk of 11.2% for a woman of the same age and race/ethnicity from the general U.S. population.
