Who is at risk for Breast Cancer? ?
A family history of breast cancer and other factors increase the risk of breast cancer.
                    Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesn't mean that you will not get cancer. Talk to your doctor if you think you may be at risk for breast cancer.    Risk factors for breast cancer include the following:            - A personal history of invasive breast cancer, ductal carcinoma in situ (DCIS), or lobular carcinoma in situ (LCIS).     - A personal history of benign (noncancer) breast disease.     - A family history of breast cancer in a first-degree relative (mother, daughter, or sister).     - Inherited changes in the  BRCA1  or  BRCA2  genes or in other genes that increase the risk of breast cancer.     - Breast tissue that is dense on a mammogram.     -  Exposure of breast tissue to estrogen made by the body. This may be caused by:                  -  Menstruating at an early age.       -  Older age at first birth or never having given birth.       - Starting menopause at a later age.                - Taking hormones such as estrogen combined with progestin for symptoms of menopause.     - Treatment with radiation therapy to the breast/chest.     - Drinking alcohol.     -  Obesity.           Older age is the main risk factor for most cancers. The chance of getting cancer increases as you get older.      NCI's Breast Cancer Risk Assessment Tool uses a woman's risk factors to estimate her risk for breast cancer during the next five years and up to age 90. This online tool is meant to be used by a health care provider. For more information on breast cancer risk, call 1-800-4-CANCER.
