The diagnosis of prostatic cancer.

The diagnosis and detection of genitourinary cancer covers a broad range of physical signs and instrumental observations which are not necessarily diagnostic. The primary diagnosis in most entities remains dependent upon histologic confirmation. Adenocarcinoma of the prostate is the most common, and at times, most difficult urogenital cancer to diagnose and detect. Many newer techniques today are designed to evaluate the stage of disease, and to detect heretofore occult metastatic foci. Immunologic assays may be of future prognostic value.
