About
RATIONALE: Chemoprevention is the use of certain substances to keep cancer from forming, growing, or coming back. Eating a diet high in lycopene, a substance found in tomatoes and tomato products, may keep cancer from forming or growing. Collecting and storing samples of blood from patients with cancer to study in the laboratory may help doctors learn more about changes that may occur in DNA and identify biomarkers related to cancer.
PURPOSE: This randomized clinical trial is studying how well lycopene works in treating patients with prostate cancer or benign prostatic hyperplasia.
