Women with BRCA1 or BRCA2 gene mutations are known to be at significantly higher risk of developing ovarian cancer as well as breast cancer. The new test is called risk of ovarian cancer algorithm (Roca), which calculates a woman’s individual risk of developing ovarian cancer based on several factors. Having the Roca blood test every four months has been shown to dramatically cut the chance of being diagnosed with late-stage ovarian cancer, which often has no or few symptoms. Women who carry a cancer-causing variant in the BRCA1 or BRCA2 gene have 44% and 17% respectively lifetime risk of ovarian cancer.
