Long-term use of contraceptives taken by millions of women linked to brain tumours, study finds

A large-scale study involving three million women has found a link between long-term use of progestogen-based contraceptives and an increased risk of developing brain tumors, specifically meningiomas. The research, conducted by Danish scientists and published in the British Medical Journal, analyzed prescription data and health records over a 15-year period. Women who used progestogen-only contraceptives for more than five years faced a significantly higher risk compared to non-users. The study highlights a potential public health concern given the widespread use of these drugs by millions of women globally. Health authorities have not yet issued new guidelines, but the findings are expected to prompt further investigation and regulatory review.

Global Impact

This study has significant public health implications, potentially altering contraceptive prescribing practices worldwide. Regulatory bodies like the FDA and EMA may initiate safety reviews, leading to updated labeling or restrictions.
