	Prostate chips are generated from ''transurethral resection of the prostate'' (TURP) procedures. These are generally for relieving urinary obstruction due to [[nodular hyperplasia of the prostate]] (benign prostatic hyperplasia); however, urinary obstruction may be secondary to [[prostate cancer]]. Thus, the job of the pathologist here, usually, is excluding an incidental [[cancer]].		Prostate chips are generated from ''transurethral resection of the prostate'' (TURP) procedures.
