My doctor wants me to get a mammogram, but I'm not sure if I should have one. What are the benefits and risks of having a mammogram?

The benefit of having a mammogram is that it can detect cancer early, when it's most treatable. It also helps to reduce the risk of dying from breast cancer. Risks include false positives (when a mammogram suggests there might be something suspicious but it turns out to be normal) and overdiagnosis (when a mammogram finds something that doesn't turn out to be cancer).
