The longer a woman uses oral contraceptives, the greater the increase in her risk of cervical cancer. One study found a 10% increased risk for less than 5 years of use, a 60% increased risk with 5–9 years of use, and a doubling of the risk with 10 or more years of use (9).

Does birth control increase your risk of cancer?

While hormonal birth control has benefits beyond pregnancy prevention, there are concerns that it may influence cancer risk. Research suggests that although oral contraceptives slightly increase the risk of breast and cervical cancers, they may also reduce risk of endometrial, ovarian, and colorectal cancers.

Can the mini pill cause cancer?

There is not enough evidence to suggest a link between the mini pill and breast cancer. If there is any increased risk, it's likely to be very small and disappear with time when you stop taking it. There is no evidence to suggest the mini-pill is linked to an increased ovarian cancer risk.
