56 year old male, never smoked, rarely drinks, 5'9" 167 lbs. cholesterol 253. Had recent exam,PSA is 8.0 blood sugar 85, BP 132/83 Concerned about the PSA level. Not painful to urinate, flow is good, prostate not enlarged. Have consumed much sugar with coffee and tea over several years. Family history of brain, lung, breast,but no colon or prostate cancer. Have used some yohimbe and other herbs. Is the PSA reading an indicator of cancer? Thanks
