Screening mammography

Screening mammography is a type of mammography that is used as a preventive measure for the early detection of breast cancer. It is typically recommended for women who have no symptoms or signs of breast abnormalities.

Overview

Screening mammography involves the use of low-dose X-rays to create images of the breasts. These images, known as mammograms, can help detect small changes in breast tissue before they become large enough to be felt as a lump or other physical symptom.

The primary goal of screening mammography is to detect breast cancer early, when it is most treatable. Early detection can increase the chances of successful treatment and survival.

Procedure

During a screening mammography, the breast is compressed between two plates in order to spread out the breast tissue. This allows for clearer images and uses less radiation. The procedure may cause some discomfort, but it is generally quick and the compression lasts only a few seconds.

Two views of each breast are usually taken during a screening mammogram: a top-to-bottom view and a side view.

Benefits and Risks

The main benefit of screening mammography is its ability to detect breast cancer early. However, like all medical procedures, it also carries some risks. These include false-positive results, overdiagnosis, and exposure to radiation.

Recommendations

Various health organizations have different recommendations for when and how often women should have screening mammograms. These recommendations typically take into account factors such as age, personal and family history of breast cancer, and other risk factors.
