My doctor says that I have to have a mammogram soon, but I don't know what that is. Can you help me understand what it is and why I need to have it?

Mammograms are X-rays of the breasts. They are used to screen for breast cancer in women who are at average risk for the disease. The goal of screening mammography is to detect breast cancers early when they are most treatable. Screening mammography can also help reduce the chance of dying from breast cancer by finding cancers before they become too large to be surgically removed.
