 According to Robert Aronowitz, before the biopsy, the patients underwent a physical examination including blood and urine assays, x-rays of the abdomen, massage of the prostate for cytology and intravenous pyelograms.For the biopsy, a part of the prostate measuring 2.5 × 1.0 × 0.5 centimeters was removed; one half was sent to a pathology laboratory to get tested while the other half was retained for permanent preparation.If the results showed cancer, a perineal prostatectomy and orchiectomy was performed on the men, followed by diethylstilbestrol treatment.
