According to the latest study, removing ovaries of women who happen to have a high risk of breast as well as ovarian cancer due to the mutations in BRCA1 and BRCA2 genes authentically reduces their risk of getting these both cancers.

Researchers carried out what’s known as the meta-analysis that combines the results of a series of studies and re-analyses them. Dr. Timothy Rebbeck, professor of epidemiology, who led the research at the University of Pennsylvania, observed the results of 10 such studies. The report was published in the January 13th issue of the Journal of National Cancer Institute. The risk reduction is pretty substantial but not as high as suggested in the previous studies.

The team concluded that it reduces a 79% risk of ovarian cancer along with 51% risk of breast cancer. The previous studies concluded that it reduces the risk by merely 95%. However, not everyone has agreed largely to the assessment as the reviewers claim that the actual reduction in the risk maybe higher than what’s presented as some surgical procedures have improved since the studies were being done.
