Radiology Exam: Mammogram

A mammogram is an X-ray exam of the breasts. 3-D mammography, also called tomosynthesis, is the most modern screening and diagnostic tool available for early detection of breast cancer.

A screening mammogram is used to detect changes in breast tissue in women who have no signs or symptoms of breast cancer. A diagnostic mammogram is used to evaluate unusual changes in the breast, such as a lump, pain, nipple discharge, or a change in breast size or shape.

Mammogram: What You Need to Know

mammogram exam
  • A mammogram can show changes in the breast tissue, such as calcifications (tiny mineral deposits in the breast tissue), or masses, such as a cyst, benign breast mass or breast cancer.
  • Annual screening mammograms are recommended by The American College of Radiology for women age 40 and older.
  • If a mammogram shows a suspicion of breast cancer, a breast biopsy will be performed to remove a small piece of tissue for examination under a microscope by a pathologist.
  • On the day of your mammogram exam, do not use any deodorant, powder or lotion on your breasts or your underarms.
