Notes and Caveats

• This tool cannot accurately calculate risk for women with a medical history of breast cancer, DCIS or LCIS. Other tools may be more appropriate for women with known mutations in either the BRCA1 or BRCA2 gene, or other hereditary syndromes associated with higher risks of breast cancer. See Other Risk Assessment Tools for more information.
• Although a patient's risk may be accurately estimated, these predictions do not allow one to say precisely which woman will develop breast cancer.
• Some women who do not develop breast cancer have higher risk estimates than those who do develop the disease.
• This tool was designed for use by health professionals. If you are not a health professional, you are encouraged to print these results and discuss them with your provider. Health-related decisions, for example, when to begin screening for breast cancer, or the interval or modality of screening, should be made after consultation with a health care professional.
• The results from this tool should not serve as the sole basis of health care decisions.
• The answers provided were used to estimate absolute risk of developing invasive breast cancer during the next 5-year period and up to age 90 (lifetime risk).
• • Factors included: patient's personal medical and reproductive history and the history of breast cancer among her first-degree relatives (mother, sisters, daughters).
  • For comparison, the tool also presents 5-year and lifetime risk estimates for a woman of the same age and race and ethnicity who is at average risk for developing breast cancer.
