Does TRT cause prostate cancer?
Last updated: January 2026
Quick Answer
Current evidence does not show that TRT causes prostate cancer. Multiple large studies have found no increased risk of prostate cancer in men on TRT. However, TRT can accelerate the growth of existing prostate cancer, which is why PSA monitoring before and during TRT is standard of care.

Safety is the most important consideration when starting TRT. Testosterone has been prescribed for decades with a well-established safety profile when properly monitored. The key is working with a qualified provider who orders regular bloodwork.
Staying Safe on TRT
- Only obtain testosterone through licensed healthcare providers and pharmacies
- Get regular bloodwork every 3-6 months (CBC, metabolic panel, hormones)
- Monitor hematocrit, PSA, and liver function
- Report any cardiovascular symptoms immediately
- Never adjust your dose without consulting your provider

Is TRT safe for long-term use?
Long-term TRT is generally safe when properly monitored. The key risks are elevated hematocrit (blood thickness), estrogen imbalance, and fertility suppression. Regular bloodwork every 3-6 months, cardiovascular monitoring, and prostate screening mitigate these risks. The TRAVERSE trial (2023) showed no increased cardiovascular risk.
What are the side effects of TRT?
Common TRT side effects include acne (20-40%), elevated hematocrit (15-25%), testicular atrophy (50-70% without HCG), mood fluctuations (15-30%), water retention (10-20%), and hair changes (10-25% with genetic predisposition). Most side effects are manageable with proper monitoring and protocol adjustments.
