What is (are) Papillary renal cell carcinoma ?
Papillary renal cell carcinoma (PRCC) is a type of cancer that occurs in the kidneys. It accounts for about 10-15% of all renal cell carcinomas.Renal cell carcinomas are a type of kidney cancer that develop in the lining of very small tubes (tubules) in the kidney.The term "papillary" describes the finger-like projections that can be found in most of the tumors. PRCC can be divided into two types: type 1, which is more common and usually grows more slowly and type 2, which are usually more aggressive .Though the exact cause of papillary renal cell carcinoma is unknown, smoking, obesity, and genetic predisposition conditions (such as hereditary leiomyomatosis and renal cell cancer) may contribute to the development of this type of cancer. Treatment often begins with surgery to remove as much of the cancer as possible, and may be followed by radiation therapy, chemotherapy, biological therapy, or targeted therapy.
