This is the process of using low-energy X-rays to examine the human breast and is used as a diagnostic and a screening tool. The goal of mammography is the early detection of breast cancer, typically through detection of characteristic masses and/or micro-calcifications.

Like all X-rays, mammograms use doses of radiation to create images which are analysed for any abnormalities.

At least one mammography screening every two years is recommended in women between the ages of 40 and 74.

Research indicates that repeated mammography starting at age 50 saves about 1.8 lives over 15 years for every 1,000 women screened. However, higher frequency use of mammography may result in overtreatment, and radiation exposure.
