Cancer
One common concern about long-term use of birth control pills is how it affects your cancer risk.
According to the National Cancer Institute (NCI)Trusted Source, using birth control pills may slightly lower your risk for endometrial and ovarian cancers.
Long-term use may slightly increase your risk for breast, liver, and cervical cancers. If these cancers run in your family, be sure to tell your healthcare provider and discuss your risks.
Blood clots and heart attack
The long-term use of birth control pills also slightly raises your risk for developing blood clots and heart attack after the age of 35. The risk is higher if you also have:
- high blood pressure
- a history of heart disease
- diabetes
After 35, it’s important to reevaluate your options for birth control with your healthcare provider.
Smoking also worsens these health concerns.
Migraines
If you have a history of migraines, the estrogen in combination pills may make them worse.
However, you may also experience no changes in headache intensity. If your migraines are associated with your menstrual period, you may even find that birth control pills ease the pain.
Mood and libido
For some women, taking birth control pills can cause changes in mood or libido. However, these types of changes are uncommon.
