(Breast X-ray; Mammogram; X-ray of Breast Tissue)
This exam uses low-dose x-rays to make a picture of breast tissue. The picture is called a mammogram.
The United States Preventive Services Task Force (USPSTF) recommends that women aged 50 years and older get a mammography every two years. Other organizations recommend screening every year starting at age 40. Women who are at high risk for breast cancer may need to have mammograms starting at an earlier age and more often. Most organizations in the United States and Canada recommend regular screening. There are some differences of opinion among these groups, such as when to start and how often to have the screenings. Talk to your doctor about what is best for you.
