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.
- I took the genetic test for hereditary breast and ovarian cancer already (the BRCA test). Will those test results tell me about tamoxifen, or do I still need to take the tamoxifen 2D6 test?
- Is the BRCA analysis test used only to detect gene mutation for breast and ovarian cancer?
