At issue are genes called BRCA1 and BRCA2. When they're mutated, the body can't repair damaged DNA as well, greatly increasing the chances of breast, ovarian and certain other cancers.
BRCA-related breast cancer appears at an earlier age than sporadic breast cancer. [9]: 89–111 It has been asserted that BRCA-related breast cancer is more aggressive than normal breast cancer, however most studies in specific populations suggest little or no difference in survival rates despite seemingly worse prognostic factors.
In general, more and more people are becoming more aware of how genetics influence disease risk.
Prophylactic salpingo-oophorectomy (removal of the ovaries and fallopian tubes to prevent cancer) is recommended at age 35-40 for people with BRCA1 mutations and at age 40-45 for people with BRCA2 mutations. [6] An increasing number women who test positive for faulty BRCA1 or BRCA2 genes choose to have risk-reducing surgery. At the same time ...
In 1996, with support from the Breast Cancer Research Foundation (BCRF) Mary-Claire King and social worker Joan Marks began the New York Breast Cancer Study, which definitively determined that incidence of breast and ovarian cancer was linked to inherited mutations of the genes BRCA1 and BRCA2. The researchers studied women of Ashkenazi Jewish ...

Furthermore, women with an inherited BRCA1 mutation undergo menopause prematurely. [120] Since BRCA1 is a key DNA repair protein, these findings suggest that naturally occurring DNA damages in oocytes are repaired less efficiently in women with a BRCA1 defect, and that this repair inefficiency leads to early reproductive failure. [119]
The increased risk for triple-negative breast cancer was 4.2 among women 40 years of age or younger who used OCs for more than one year, while there was no increased risk for women between the ages of 41 and 45. Also, as duration of OC use increased, triple-negative breast cancer risk increased.
