Could the contraceptive pill reduce risk of ovarian cancer?

Researchers found that women who had used the oral contraceptive pill had a lower risk of ovarian cancer, with a 39% reduced risk for those who had given birth to two or more children. The study also identified certain biomarkers and lifestyle factors associated with a lower risk of ovarian cancer, including lower body weight and short...
