Summary

This study tests whether taking curcumin (a compound found in turmeric) after prostate removal surgery can help keep prostate cancer from coming back. About 650 men with early-stage prostate cancer who have had their prostate removed will take curcumin or a placebo. The main goal is to see if curcumin improves the time without cancer recurrence, measured by PSA levels.
