Answer

If complete surgical resection is not feasible, an open incisional biopsy to evaluate histologic characteristics should be performed. Core biopsy is often deemed inadequate because of insufficient tissue sample and sampling error. For suspected tumors of the bladder, prostate, and vagina, endoscopic biopsy may be required.
