medical community: BRCA1 and BRCA2. The names stand for breast cancer susceptibility gene 1 and breast cancer susceptibility gene 2. BRCA1 is found on chromosome 17 and BRCA2 is found on chromosome 13. Mutations in either gene increase a person’s risk of breast, ovarian, and other cancers...
I didn’t find out I had the BRCA1 gene mutation until 2 weeks after I was diagnosed, one week after I had already had a double mastectomy. Even though my breast cancer was stage 1, it was also “triple negative,” or the most aggressive type, and my mother had survived three breast...
A specific Mutation in the BRCA1 gene is linked to breast cancer. Variation Extent to which a thing varies; amount of departure from a position or state; amount or rate of change. Mutation A deviation from the standard DNA sequence. The Mutation caused a malfunctioning protein, leading to di...
