Mammography is a low-dose X-ray used to examine breast tissue.
Successful treatment of breast cancer is often linked to early detection. The American Cancer Society recommends a screening mammogram every year for women beginning at the age of 40. Women who have had breast cancer, or those with a family history of breast cancer, should talk with their physician about screening recommendations.
Screening mammography is used to find breast changes in women who have no signs or symptoms of a problem.
Diagnostic mammography is used to investigate suspicious breast changes, such as a breast lump, breast pain, an unusual skin appearance, nipple thickening or nipple discharge. It also is used when it is hard to get a screening mammogram because of breast implants, for example.
