New research from Oxford’s epidemiology unit has confirmed that birth-control pills increase the risk of cervical cancer.

The study, published in the Lancet, involved over 50,000 subjects and research from 24 countries. Lead researcher Dr. Jane Green stressed that the increase in risk was “small and outweighed by reduced risks for ovarian and womb cancer.”

The study also found that risk levels returned to normal in subjects who had not used the drug for ten years or more.
