My doctor says I have to have a mammogram. What is a mammogram and why is it so important?

A mammogram is an X-ray of the breast. It’s used to detect any changes in the breast tissue that could be caused by cancer. The goal of the test is to find any abnormal areas in the breast that may not show up on a regular mammogram. If there are any suspicious areas, further tests can be done to determine if they are cancerous.
