'23andMe Saved My Life'

In a recent CBS News story, one woman says that the direct-to-consumer genetic testing services her husband ordered through 23andMe saved her life. Upon learning that she's a BRCA1 mutation carrier via 23andMe, 31-year-old Jill Steinberg underwent genetic counseling and had her test results confirmed before undergoing a double mastectomy. Over at his blog, her husband, Jon Steinberg, says that he ordered two DTC spit kits on DNA day and the couple "did this testing by chance." Since having learned that his wife was at an increased risk for developing breast cancer, "we've become huge advocates of it in conjunction with counseling, repeat testing, and a study of family history," he writes. Jill Steinberg, who as a carrier of the BRCA1 mutation is also at an increased risk of developing ovarian cancer, tells CBS News that she plans to have her ovaries removed once she's 35.
