Birth Control Cause 5X More Brain Tumors & Pfizer Has Known This Data For Decades

Hundreds of women across the U.S. and UK are taking legal action against Pfizer over Depo-Provera, the birth control injection now linked to brain tumor development.

A French study found women using Depo-Provera for more than a year were five times more likely to develop a meningioma—a brain tumor that often requires surgery. Over 18,000 women in that study alone underwent brain operations between 2009 and 2018.

More than 40 million women have already used Depo-Provera worldwide. By 2021, it was estimated that one in four sexually active women in the U.S. had relied on these injections.
