Hormonal components in over-the-counter dietary supplements may promote the progression of prostate cancer and decrease the effectiveness of anti-cancer drugs, researchers at UT Southwestern Medical Center have discovered.

The researchers also recommend that documentation of supplement usage become part of routine health assessments for all patients, particularly cancer patients.
