The statistics are scary: some 40,000 women are dying from breast cancer each year.
But some breast cancer survivors are getting double mastectomies they don't need, in the wrong belief it helps keep cancer from coming back.
That's according to a new University of Michigan study. For some survivors, the study says, the fear of cancer returning is so strong, they're getting risky surgeries for some false peace of mind.
If you've survived breast cancer, it can make medical sense to get that cancer-ridden breast removed.
