Hormone medication could increase risk of brain tumours, French study finds

Patients taking certain progestogens as a contraceptive or for gynaecological conditions may be more likely to develop growths, researchers say

Millions of women around the world who use certain hormone drugs for contraception and to manage conditions such as endometriosis may have a raised risk of rare, usually benign, brain tumours, researchers say.

Scientists found that prolonged use of certain progestogen medications was linked to a greater risk of meningioma, which are tumours (usually noncancerous) that form in tissues around the brain.
