One in eight women will develop breast cancer in her life; 70 percent of these women have no known risk factors for the disease. Women ages 40 to 49 should talk to their doctor and make an informed decision about whether mammography is appropriate based on their family history and general health. The U.S. Preventive Services Task Force recommends that women ages 50 to 74 have a mammogram every two years.
A mammogram is an X-ray of the breast that's used to check for abnormalities in the breast tissue. Mammograms can help detect tumors or other cysts that may indicate the presence of breast cancer.
When found early, breast cancer is highly treatable and chances of survival are best. Visit WebMD for more information on breast cancer and mammograms.
