A new study suggests mammograms could raise the risk of breast cancer in young women whose genes put them at higher risk for the disease.
The study, done by European cancer agencies, found the added radiation from mammograms could be harmful to women with the breast cancer gene.
About one in 400 women have the gene.
Doctors say mammograms do save lives, and are clearly beneficial for women age 50 and older.
Experts are divided about their value in younger women, with some saying MRIs are a better screening method.
