Hepatitis* Finding of a PSA > 10 nmol/ml is suggestive of cancer and > 35 ngml is almost diagnostic of advanced prostate cancer. A decrease in PSA to the normal range following hormonal ablation is a good prognostic sign* Trans rectal ultrasonogram in evaluation of carcinoma prostate most useful for - Taking guided biopsy*** CA of prostate arise from peripheral zone** and BPH from Transition zones**
