TID-BITS• Prostate is #1 most common malignancy in men but NOT
#1 killer. WHY?• 80% over 80• Every elderly male presenting with widespread bone
metastases is carcinoma of the prostate until proven otherwise
• PSA (Prostate Specific Antigen) has been controversial as a screening test but is GREAT for follow up of a known prostate cancer
