Women taking the oral contraceptive pill that includes both estrogen and progesterone are at a lower risk of developing ovarian cancer, according to researchers in a new study. The findings are based on data collected from over 1.8 million women in a national Danish health database between 1995 and 2014. The researchers found that women who had used the contraceptive pill with both hormones were 34% less likely to get ovarian cancer than women who had not used the pill. Further the longer women used the pill, the more their risk of ovarian cancer dropped. Read more in a story from The Guardian.
