KNOWLEDGE IS POWER… Know the Risks
Some risk factors, like a person’s age or race, can’t be changed. Others are linked to cancer-causing factors in the environment. Still others are related to personal behaviors, such as smoking, drinking, and diet. Some factors influence risk more than others, and your risk for breast cancer can change over time, due to factors such as aging or lifestyle.
Common Genetic Factors
- Age: Two out of three women with invasive cancer are diagnosed after age 55.
- Race: Breast cancer is diagnosed more often in Caucasian women than women of other races.
- Family History and Genetic Factors: If your mother, sister, father or child has been diagnosed with breast or ovarian cancer, you have a higher risk of being diagnosed with breast cancer in the future. Your risk increases if your relative was diagnosed before the age of 50.
- Personal Health History: If you have been diagnosed with breast cancer in one breast, you have an increased risk of being diagnosed with breast cancer in the other breast in the future. Also, your risk increases if abnormal breast cells have been detected before.
- Menstrual and Reproductive History: Early menstruation (before age 12), late menopause (after 55), having your first child at an older age, or never having given birth can also increase your risk for breast cancer.
- Dense Breast Tissue: Having dense breast tissue can increase your risk for breast cancer and make lumps harder to detect. Several states have passed laws requiring physicians to disclose to women if their mammogram indicates that they have dense breasts so that they are aware of this risk. Be sure to ask your physician if you have dense breasts and what the implications of having dense breasts are.
