A recent study published in JAMA Network Open on March 15, 2026, found that despite expanded guidelines recommending BRCA testing for more patients, significant barriers remain. The research, led by Dr. Allison Kurian at Stanford University, analyzed data from over 1.2 million patients and found that only 18% of eligible individuals received testing.
Key barriers identified include high out-of-pocket costs, lack of awareness among patients and providers, and limited access to genetic counseling in rural areas. The study highlighted that Black and Hispanic patients were 30% less likely to be tested than white patients, even after adjusting for insurance status.
Dr. Kurian emphasized that targeted therapies for BRCA-mutated cancers, such as PARP inhibitors, are life-saving, but their benefits are not reaching all populations equitably. The study calls for policy changes to reduce cost barriers and increase education efforts.
