Test-takers' perspectives on consumer genetic testing for hereditary cancer risk.

Purpose: With few exceptions, research on consumer genetic testing for hereditary cancer risk has focused on tests with limited predictive value and clinical utility. Our study advances the existing literature by exploring the experiences and behaviors of individuals who have taken modern consumer genetic tests for cancer susceptibility that, unlike earlier tests, screen for medically significant variants.

Methods: We interviewed 30 individuals who had undergone consumer genetic testing for hereditary cancer risk between 2014 and 2019.
