A mammogram is an x-ray of the breast that looks for changes that may be signs of breast cancer. Getting regular screening with a mammogram is the most reliable way to find breast cancer early. Breast cancer that's found early, when it's small and has not spread, is easier to treat successfully.
Women between 40 and 44 should have the option to start screening with a mammogram every year. Women 45 to 54 should get mammograms every year. Women 55 and older can switch to a mammogram every other year, or they can choose to continue yearly mammograms.
