The BRCA gene is a gene, that when mutated is commonly associated with higher rates of breast cancer. Many genomics companies have developed tests to ensure that women who are concerned about the possibility of developing breast cancer are able to be tested for the gene.
Women with family histories of breast cancer are advised to get tested for the BRCA mutation to determine their risk for developing breast cancer.
Not all mutations of the BRCA gene can be dangerous, but many find that it’s still a wise idea to get tested.
A harmful mutation of the gene means is that the DNA repair mechanism is disabled, meaning that your cells can’t repair mutations that may arise.
