Progestogen Contraceptives Linked to Increased Brain Tumor Risk: New Danish Study Findings
A major Danish study reveals a significant link between various progestogen-based contraceptives and an increased risk of developing benign meningioma brain tumors.
Progestogen Contraceptives and Meningioma Risk
A comprehensive research project conducted in Denmark has identified a notable link between the use of progestogen-containing contraceptives and the development of meningioma, a common type of benign brain tumor. Published in JAMA Network Open, this research highlights that the risk profile extends beyond injectable forms to include various oral contraceptives and intrauterine devices (IUDs).
Understanding the Clinical Findings
Dr. Charlotte Wessel Skovlund of the Danish Medicines Agency and her team examined data from national registries covering the period between 2000 and 2024. By comparing 1,473 women diagnosed with meningioma against 14,717 matched control patients, the team uncovered that eight out of 12 progestogen formulations showed statistically significant associations with tumor development.
Injectable medroxyprogesterone emerged as the most significant factor, carrying an odds ratio more than four times higher than that of non-users. Other formulations, including oral desogestrel and various IUDs, also demonstrated elevated risks. Notably, the researchers observed that the heightened risk typically dissipates five years after a patient stops using the hormonal contraceptive.
Contextualizing the Medical Evidence
While the findings are significant, medical professionals emphasize that meningioma remains an uncommon condition, affecting roughly one in 10,000 individuals. Dr. Melanie Davies of University College London noted that progestogens remain vital for managing gynecologic disorders and providing effective birth control. She cautioned that the study results should not deter women from necessary hormonal treatments, but rather encourage informed decision-making.
The biological basis for these findings appears rooted in the presence of progesterone receptors on the surface of approximately 87% of all meningiomas. Historical clinical observations have frequently documented tumor growth in the presence of exogenous progesterone, with regression often occurring once the hormonal stimulus is removed.
Regulatory and Clinical Responses
Global health authorities have already begun responding to these trends. The U.S. FDA recently mandated a label update for depot medroxyprogesterone to include warnings regarding meningioma, while the American College of Obstetricians and Gynecologists has updated its guidance to foster better communication between providers and patients regarding long-term contraceptive risks.

Frequently Asked Questions
What is a meningioma?
A meningioma is the most common form of benign brain tumor that arises from the membranes surrounding the brain and spinal cord. While typically non-cancerous, these tumors can grow and cause significant health issues if they exert pressure on sensitive brain tissue.
Does the risk of meningioma persist after stopping birth control?
According to the Danish study, the excess risk associated with progestogen contraceptives appears to vanish five years after the patient discontinues the use of the medication. This suggests that the hormonal influence on tumor development is reversible.
Should I stop taking my hormonal contraceptive immediately?
No, you should not make changes to your medication without consulting your healthcare provider. While the study shows an increased risk, meningiomas remain rare, and the benefits of hormonal contraceptives for preventing pregnancy or treating conditions like endometriosis often outweigh the risks.
