The problem of misunderstanding 23andMe genetic test results

Home delivery for everything from fresh produce to custom-selected clothing has become a way of life for many Americans. While most home-delivery conveniences are generally changing our lives for the better — giving us more time and choices — at-home genetics kits that reveal information about the risk of developing certain cancers represent a risky step in our on-demand culture. The FDA recently gave 23andMe the green light to sell the first direct-to-consumer tests for mutations in the BRCA1 and BRCA2 genes, which are linked to serious risks of developing cancer. All a buyer has to do is ship a saliva sample to the company. Six to eight weeks later, the results are delivered through an online portal. Mutations in the BRCA1 and BRCA2 genes were initially linked to breast cancer, hence the names (“BReast” and “CAncer”). We now know that they also increase the risk of ovarian, prostate, and pancreatic cancer. Women with mutations are at least five times more likely than women without them to develop breast cancer, and up to 20 times more likely to develop ovarian cancer.
