Scientists Discover Testosterone Could Actually Protect Against Deadly Brain Cancer

Cleveland Clinic researchers found that lowering androgen hormones sped up glioblastoma growth in preclinical models.

In a review of more than 1,300 men with glioblastoma, supplemental testosterone was linked to a 38% lower risk of death.

The findings suggest hormone biology may influence outcomes in this aggressive brain cancer.

Researchers say the results need to be confirmed in clinical trials before changing treatment.
