A mammogram is a special type of X-ray that takes images of breast tissue. It is an important breast cancer screening tool that can help find cancer early, sometimes before there are signs or symptoms.
For women at average risk, mammogram screening generally begins at age 40, but when and how often you should be screened can depend on your age, health history and other risk factors.
Talk with your health care provider about the screening schedule that’s right for you. Finding breast cancer early can lead to more treatment options and better outcomes.
