To determine the presence as well as the malignancy of a tumor, the pathologist examines tissue taken from the prostate for the presence of malignant cells. The material may come from a biopsy or from a transurethral resection of the prostate (TUR-P). The structure of the tissue (histology) and the appearance of the cells (cytology) are important for the evaluation. The more precise the pathological findings with regard to the extent, localization and aggressiveness of the tumor, the more targeted a patient can be treated in the presence of prostate carcinoma.

For this purpose, the West German Prostate Center has been working for more than 15 years with PD Dr. W. Mellin and Dr. B. Melzer from the Institute of Pathology and Cytology Cologne Weyertal. The two specialists have a wide range of state-of-the-art examination techniques (including immunohistochemistry, DNA cytometry) at their disposal for the histopathological and immunohistological examination of prostate biopsies and surgical specimens.
