BRCA1 (BReast CAncer gene 1) is a gene that plays a role in the repair of DNA and the prevention of cancer. When the BRCA1 gene is functioning properly, it helps to prevent the development of cancer by repairing damaged DNA and regulating cell growth. However, certain mutations (changes) in the BRCA1 gene can increase a person’s risk of developing breast and ovarian cancer.
Mutations in the BRCA1 gene are inherited, which means they are passed down from one generation to the next. People who have a family history of breast or ovarian cancer may be at an increased risk of carrying a BRCA1 mutation. Testing for BRCA1 mutations is usually done through a blood test or a saliva test, and results can help determine a person’s risk of developing cancer and guide their cancer prevention and screening strategies.
It is important to note that not everyone who carries a BRCA1 mutation will develop cancer. There are many other factors that can influence a person’s risk of cancer, including their age, lifestyle, and overall health. If you have concerns about your risk of breast or ovarian cancer, it is important to speak with a healthcare professional. They can help determine if testing for BRCA1 mutations is appropriate for you and discuss your options for cancer prevention and screening.
