What you don't know can hurt you: adverse psychologic effects in members of BRCA1-linked and BRCA2-linked families who decline genetic testing.

Abstract

In BRCA1/2-linked families, persons with high levels of cancer-related stress who decline genetic testing may be at risk for depression. These family members may benefit from education and counseling, even if they ultimately elect not to be tested, and should be monitored for potential adverse effects.
