BRCA1 is a gene that plays an important role in the body’s ability to repair damaged DNA and maintain healthy cells. Mutations in this gene can cause an increased risk for certain types of cancer, including breast cancer and ovarian cancer. Understanding what BRCA1 is, how it affects health, how it is tested and what treatment options are available can help people make informed decisions about their health.
What is BRCA1?
BRCA1 stands for BReast CAncer gene 1. It is a gene on chromosome 17 that has the instructions for making a protein called BRCA1. This protein helps repair damaged DNA and helps keep cells from growing out of control, which can lead to cancer. Mutations, or changes, in the BRCA1 gene can cause it to not work properly, which can increase the risk of certain types of cancer.
How Does BRCA1 Affect Health?
People with mutations in the BRCA1 gene have an increased risk for certain types of cancer, including breast cancer and ovarian cancer. Women with BRCA1 mutations have an estimated lifetime risk of breast cancer of up to 87%, and an estimated lifetime risk of ovarian cancer of up to 44%. Men with BRCA1 mutations also have an increased risk of breast cancer, although the risk is lower than for women.
How is BRCA1 Tested?
BRCA1 testing is available for people who have a family history of certain types of cancer. Testing can be done with a blood or saliva sample, and it looks for mutations in the BRCA1 gene. It is important to talk to a healthcare provider about the risks and benefits of testing before making a decision.
What Are the Treatment Options for BRCA1?
Treatment options for people with BRCA1 mutations vary depending on the individual and their risk for cancer. Surgery, such as removal of the breasts or ovaries, may be recommended for people at high risk of cancer. Other treatment options may include medication to reduce the risk of cancer, increased monitoring for signs of cancer, and lifestyle changes to reduce the risk of cancer.
