“Some birth control methods were linked to a higher risk of meningioma in a large Danish study.
Meningiomas are the most common brain tumors in adults.
Most are noncancerous, but they can still cause seizures, memory changes, vision problems, or require surgery.
Researchers analyzed nationwide health records from about 3 million females aged 15 to 59 over 25 years.
They compared 1,473 women diagnosed with meningioma with 14,717 matched controls.
The strongest link was seen with injectable medroxyprogesterone. High-dose levonorgestrel IUDs and some combined or progestogen-only pills were also linked to increased risk.
Low-dose levonorgestrel IUDs did not show a clear increase.
This does not mean people should stop contraception suddenly. The absolute risk is still low, and birth control decisions depend on many health factors.
But it suggests the type of progestogen may matter.
