Radiation Exposure Increases Breast Cancer Risk

A new study looking at women with the BRACA-1 or BRACA-2 breast cancer gene mutation finds those who had a mammogram or chest x-ray before they were 30 are at an increased risk of getting breast cancer.

That's compared to women who have the mutation but weren't exposed to the radiation.

Radiation exposure is a known risk factor for breast cancer.

Researchers recommend those women choose an MRI scan instead of a mammogram or x-ray to check for the disease.
