Researchers from the Collaborative Group on Epidemiological Studies on Endometrial Cancer estimate that in the
past 50 years (1965 - 2014) about 400000 cases
of endometrial cancer have been prevented by oral
contraceptive use in high - income countries, including about 200000 in the last decade (2005 - 2014).
For example, 35 %
of satisfied oral
contraceptive users have skipped at least one pill in the
past three months, compared with 48 %
of dissatisfied users.8 Consistent
contraceptive use helps women and couples prevent unwanted pregnancies and plan and space those they do want.
