What is Small Cell Carcinoma of the Renal Pelvis?Small cell carcinoma of the renal pelvis is a rare type of tumor that usually develops in the 6th decade of life in the central region of the kidney called the renal pelvis. Small cell carcinoma of the renal pelvis can also have properties of tumors that originate from the hormone-secreting nerve cells called neuroendocrine cells. Small cell cancers are rare types of cancers that can originate from any part of the body but usually from the lungs. Small cell cancer has the ability to grow rapidly and spread to other distant parts of the body.

Disease CausesThere is no well-known cause; however certain hereditary and genetic mutations (a change in the sequence of DNA or genetic material) are considered potential causes for the development of small cell carcinoma of the renal pelvis. Cigarette smoking and chronic inflammation of the kidneys are also contributing risk factors for the development of small cell carcinoma of the renal pelvis.
