A mammography is a diagnostic imaging procedure performed to diagnose breast cancer. Typically, a woman gets a mammogram when she is 40 years old or older. This test is important to detect a lump or abnormal tissue. It helps physicians decide whether further tests are needed. A standard screening mammogram consists of two views: the craniocaudal view and the mediolateral-oblique view. The craniocaudal view shows the breasts from above. The mediolateral-oblique view allows for a more detailed visualization of the upper chest and breast tissue. Once the screening mammogram is completed, the radiologist will discuss the results with the patient and provide a written report.
