Breast and Ovarian Cancer Risk Genes Have a Link to Fertility
Genes that increase a woman's risk of breast and ovarian cancer also make her more fertile, according to researchers. Women with the BRCA1 and BRCA2 mutations are more likely to have children who could develop the diseases, and the fact that the genes have not been "weeded out" by natural selection indicates they may confer advantages as well as harmful effects. University of Utah scientists found that women possessing genes bore significantly more children, especially those born before 1930 who lacked access to modern contraception.
