Which Breast Tests Are Best?

(2 of 2)

•Genetic Testing Experts believe that 5% to 10% of breast cancer is hereditary. Women who have mutations in either the BRCA1 or BRCA2 gene have up to an 80% risk of developing breast cancer, and half fall prey by age 50. The abnormal genes are easily found in a cell sample swabbed from the mouth. Women who test positive are usually offered enhanced cancer surveillance, including MRI follow-up, which many insurance companies will at least partly cover.

Who should get it? A federal task force has recommended genetic testing for women with two first-degree relatives-- mother or sister--with breast cancer, one of whom had the disease diagnosed by age 50. --By Coco Masters
