Understanding the BRCA genes
BRCA1 and BRCA2 are important cancer-fighting genes. When they function normally, the BRCA genes can help keep tumors from forming.
We all have BRCA1 and BRCA2 genes. Only some of us have mutations in these genes. For the small number of people who have BRCA gene mutations, most are inherited or passed down from one or more generations in families.
BRCA1 mutations are associated with an increased risk for:
- Breast cancer, including Triple Negative Breast Cancer
- Ovarian cancer
- Pancreatic cancer
- Prostate cancer
BRCA2 mutations are associated with an increased risk for:
- Breast cancer
- Ovarian cancer
- Melanoma
- Pancreatic cancer
- Prostate cancer
You can undergo genetic testing to check for gene changes related to many different types of cancer, like breast cancer or colon cancer. While these tests can confirm an inherited risk of cancer, they don’t mean you will definitely develop cancer. Your doctor can help you understand your results and give you different options for reducing your risk for cancer.
The only way to know if you have an inherited gene mutation is to have genetic testing done.
