第一节肾肿瘤（The first kidney tumor） Chapter 57 tumor of genitourinary and male reproductive system Tumors can be found in all parts of the genitourinary and male reproductive system. The most common prostate cancer in Europe and the United States has a significant growth trend in China in recent years. The incidence of penile cancer in the reproductive system in China has decreased significantly in the past.
