Breast Cancer Risk Factors
Knowledge about your personal breast cancer risk factors is an important step toward breast cancer prevention.
Various factors affect each woman’s risk for developing breast cancer. For instance, women with first-degree relatives diagnosed with breast cancer or a history of certain genetic mutations with their family are at higher risk than women within no history or limited family history of breast cancer.
Some of these factors, such as family history, women have no control over. However, lifestyle choices also affect a woman’s chances of developing breast cancer. Living a physically active lifestyle and maintaining a healthy diet may help women to reduce risk of developing breast cancer.
Women should take steps to understand their personal risk for breast cancer, as well as ways they can make lifestyle choices that support their overall health. Below is a list of just some known risk factors for breast cancer.
Major Breast Cancer Risk Factors
- Family history (any first-degree relative, like mother, sister and/or daughter), with elevated risk if there is a history of pre-menopausal or a bilateral (both breasts) breast cancer.
- Previous high-risk biopsy.
- Previous personal history of breast cancer.
- History of chest wall radiation.
- Known BRCA1 or BRCA2 mutation in the family.
Minor Breast Cancer Risk Factors
- Early onset of menstrual period.
- First birth after age 30 or no pregnancy.
- Greater than 1 ounce of alcohol per day.
- Prolonged use of post-menopausal hormones.
- Body weight > 30 percent of normal.
