Testosterone therapy under scrutiny in prostate cancer patients
NCT ID NCT07278362
First seen Jun 27, 2026 · Last updated Jul 23, 2026 · Updated 2 times
Summary
This study looks at whether testosterone replacement therapy (TRT) is safe for men with low-risk prostate cancer who also have low testosterone. Researchers will monitor 35 men for 12 months to see if the cancer gets worse or if they need stronger treatment. The goal is to help manage symptoms of low testosterone without increasing cancer risk.
