Genetics company 23andMe—popular for their DTC ancestry tests—has been FDA approved for their mail-order breast cancer tests. Consumers can check whether they possess one of three mutations to their aptly-named BRCA1 and BRCA2 genes, which increase breast cancer risk by 45%-85%. Thing is, there are 1,000 known variations of those genes, and it doesn’t even test the most common. Also, the genes tested mainly affect women of Ashkenazi Jewish descent. Also, if a patient doesn’t test positive for these mutations they may think they’re in the clear breast cancer-wise. Also, some physicians are worried about the mental health effects of learning you may be at risk for cancer without being counseled through it by a professional. But hey, they send the tests to your home so that’s convenient!
