Your question: Can you carry breast cancer gene?

How do you know if you carry the breast cancer gene?

The BRCA gene test is a blood test that’s done to determine if you have changes (mutations) in your DNA that increase the risk of breast cancer. Mutations in either breast cancer gene — BRCA1 or BRCA2 — significantly increase the risk of: Breast cancer.

Can a father carry the breast cancer gene?

Most inherited cases of breast cancer are associated with two abnormal genes: BRCA1 (BReast CAncer gene one) and BRCA2 (BReast CAncer gene two). Men are just as likely as women to have an abnormal breast cancer gene.

Who carries the breast cancer gene?
