Phase 2 trial to test if mushroom tablets could slow prostate cancer

City of Hope, a world-renowned independent research and treatment center for cancer, diabetes and other life-threatening diseases, is now recruiting patients for a Phase 2 clinical trial to investigate whether pills containing white button mushroom extract could regulate the immune system, affecting prostate-specific antigen (PSA) levels to either remain stable or decline. Heightened levels of PSA in men may indicate the existence of prostate tumors.
