The earlier you find the disease, the easier it is to treat. Mammograms, an X-ray of the breast, can show tumors before they get large enough to feel. The American Cancer Society says women ages 45-54 with an average risk level should get a yearly mammogram. Starting at age 55, mammograms can be perfomed every 2 years. Continue them as long as you’re in good health. The U.S. Preventive Services Task Force says until you’re 50 you should talk to your doctor about your need for testing. After that, get a mammogram every 2 years from ages 50 to 74. You don’t have to stop at 75; the group just doesn’t assess the pros and cons. You can work it out with your doctor.
