What is a breast and ovarian cancer genetic test?
The blood test for breast or ovarian cancer looks for changes, or mutations, in the BRCA1 and BRCA2 genes. Normally, these genes help control cell growth. Cancer occurs when cells change and grow out of control. Women who inherit these BRCA gene changes have a higher-than-average chance of getting breast or ovarian cancer.
