Genetic Testing For Cancer Risk Is On The Rise -- But Is It Smart?

At the upcoming meeting of the American Society of Clinical Oncologists (ASCO), more than 150 presentations are planned on recent discoveries about how genes may predict cancer. The presenters range from health research luminaries like the Mayo Clinic to for-profit companies such as Myriad Genetics. The data from the closely watched conference will no doubt fuel the growing trend of healthy people getting tested to determine their future risk of developing cancer—and the resulting questions about who really needs to undergo such testing.
