Women who have inherited the harmful mutations of the BRCA1 or BRCA2 gene are generally at a higher risk of developing breast and/or ovarian cancer, Aug 10, 2020 New guidelines illuminate how these mutations can increase risk, but the these genes in colorectal and pancreatic cancer, the key take-home A positive test result indicates that a person has inherited a known harmful variant in BRCA1 or BRCA2 (these are typically called “pathogenic” or “likely pathogenic” variants on laboratory test reports) and has an increased risk of developing certain cancers. If you test positive for an abnormal BRCA1, BRCA2, or PALB2 gene and you have never had breast cancer, you now know that you are at much higher-than-average risk of developing it over the course of your lifetime. The average lifetime risk of breast cancer for women is about 12%. It’s natural to feel worried if you’ve tested positive for a BRCA1, BRCA2, or PALB2 gene mutation. It’s true that these gene mutations can significantly increase your chances of developing breast cancer.

Normally, these genes help prevent cancer by producing proteins that repair damage to DNA (the genetic material in a cell). Certain changes (pathgenetic variants) in these genes disrupt the function of the protein product and are associated with hereditary breast and ovarian cancers. Laura, 27, opted to have a preventive double mastectomy after testing positive for a BRCA1 gene mutation.
