The National Cancer Institute (NCI) and the National Surgical Adjuvant Breast and Bowel Project (NSABP) Biostatistics Center have developed this Breast Cancer Risk Assessment Tool, a Web tool that allows a health professional to project a woman’s individualized estimate of risk for invasive breast cancer over a 5-year period and over her lifetime (to age 90).
