Newsviews: Testing genes to determine cancer risk

Gregg Kaplan lost his first wife to breast cancer. She learned, after her diagnosis, that she carried the BRCA 1 gene mutation which put her at greater risk of developing breast and ovarian cancer.

Kaplan's second wife also carried the mutation, but underwent a preventative mastectomy.
