Psychological Impact of Genetic Testing for Hereditary Nonpolyposis Colorectal Cancer

Abstract

Although HNPCC genetic testing does not result in long-term adverse psychological outcomes, unaffected mutation carriers may experience increased distress during the immediate postdisclosure time period. Furthermore, those with higher levels of baseline mood disturbance, lower quality of life, and lower social support may be at risk for both short- and long-term increased distress.
