BRCA gene mutations

Description

BRCA1 and BRCA2 genes are tumour suppressor genes. Changes to genes are called mutations. Mutations of the BRCA genes are inherited from one or both parents, and these mutations increase the risk of cancer.

Women with BRCA mutations have a higher risk of breast and ovarian cancers. Men with BRCA mutations also have a higher risk of breast cancer, and may have a higher risk of prostate cancer. The risk of other cancers – such as stomach or pancreatic cancer – may also be higher with BRCA mutations.
