Biopsy is a standard diagnostic method of squamous cell carcinoma of penis. Biopsy offers useful information to cancer staging and histological classification. It can confirm the small lesions and encroaching depth. The bigger tumors are, the easier to judge infiltration degree through check-up and imaging examinations. Combing these detailed information together would help to stage cancer correctly, and to judge the possibility of microcosmic metastases without obvious clinical cancer metastatic symptoms (namely, to touch metastatic lymph nodes).
