Early menopause may occur in women with BRCA gene, new study finds
Date:1/28/2013

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 will be published online in Cancer on January 29, 2013.

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.

"Our findings show that mutation of these genes has been linked to early menopause, which may lead to a higher incidence of infertility,'' said senior author Mitchell Rosen, MD, director of the UCSF Fertility Preservation Center and associate professor in the UCSF Department of Obstetrics, Gynecology and Reproductive Sciences. "This can add to the significant psychological implications of being a BRCA1/2 carrier, and will likely have an impact on reproductive decision-making,'' Rosen said.

Mutations in either of the genes BRCA 1 or BRCA 2 can produce a hereditary, lifetime risk of developing breast cancer and ovarian cancer. Some women decide to reduce their risk by undergoing prophylactic surgery to remove at-risk tissue, including their breasts and ovaries. The abnormal genes are the most identified inherited cause of breast cancer carriers are five times more likely to develop breast cancer than t
