Women with harmful mutations in the BRCA gene, which put them at higher risk of developing breast and ovarian cancer, tend to undergo menopause significantly sooner than other women, allowing them an even briefer reproductive window and possibly a higher risk of infertility, according to a study led by researchers at UC San Francisco.

Moreover, the study showed that carriers of the mutation who are heavy smokers enter menopause at an even earlier age than non-smoking women with the mutation.

While the authors note that further research is needed, given the size and demographics of the study, women with the abnormal gene mutation should consider earlier childbearing, and their doctors should encourage them to initiate fertility counseling along with other medical treatments, the scientists said.

The study was published online in the journalĀ CancerĀ on Jan. 29.

This is the first controlled study to explore the association between BRCA1 and BRCA 2 and the age at onset of menopause, the authors said.
