A mammogram is a low-dose x-ray exam of the breasts to look for changes that are not normal. A mammogram allows the doctor to have a closer look for changes in breast tissue that cannot be felt during a breast exam. Women ages 50 to 74 years should get a mammogram every 2 years. Women younger than age 50 should talk to a doctor about when to start and how often to have a mammogram.
