The Breast Cancer Risk Assessment Tool allows health professionals to estimate a woman's risk of developing invasive breast cancer over the next 5 years and up to age 90 lifetime risk. The tool may underestimate risk in black women with previous biopsies and Hispanic women born outside the United States. Further studies are needed to refine and validate these models. This tool cannot accurately estimate breast cancer risk for: Women carrying a breast-cancer-producing mutation in BRCA1 or BRCA2 Women with a previous history of invasive or in situ breast cancer lobular carcinoma in situ or ductal carcinoma in situ Women in certain other subgroups see Other Risk Assessment Tools section. Although a woman's risk may be accurately estimated, these predictions do not allow one to say precisely which woman will develop breast cancer. In fact, some women who do not develop breast cancer have higher risk estimates than some women who do develop breast cancer.
There are more than twice as many new breast cancer cases annually than new cases of cancer in any other site. A growing body of evidence shows the link between healthy lifestyle choices and a lower risk of developing breast cancer. As a result, being active, eating a well-balanced diet and maintaining a normal body weight are three simple but crucial lifestyle choices. Mammography is widely accepted as the best method to detect breast cancer early, before it becomes palpable.
Breast cancer is the most common cancer in women both in the developed and less developed world. It is estimated that worldwide over women died in due to breast cancer Global Health Estimates, WHO Incidence rates vary greatly worldwide from
