Use requires supervision by a qualified healthcare professional and a risk-benefit assessment. | | Chemoprevention of prostate cancer | Long-term studies (e.g., REDUCE trial) suggest a reduction in low-grade prostate cancer incidence but an increase in higher-grade disease; clinical consensus remains uncertain. | Off-label; not recommended outside trial settings. |
