Multigene Test Increasingly Used to Assess Breast Cancer Risk
May 10, 2018
(UPI) – New research suggests women are increasingly foregoing BRCA tests, which only test for mutations in either of the BRCA1 and BRCA2 genes, opting instead for more comprehensive tests that detect mutations in a larger number of genes. Because multigene tests can identify a variety of mutations, the risks of which aren’t well established, health researchers hypothesized the increase in such tests would lead to an uptick in prophylactic mastectomies — the removal of both breasts to prevent the development of cancers. However, the latest survey of breast cancer testing showed changes in test preferences haven’t resulted in more mastectomy surgeries.
