The other names for renal cancer include renal cell carcinoma, hypernephroma, kidney cancer, and renal adenocarcinoma. This is among the ten most common cancers that affects adults in the country. The function of the kidney is to eliminate the waste from the body including excess water and salt. The organ also helps control the blood pressure and ensures the body has enough red blood cells by making a hormone called erythropoietin. Minute tubes called tubules present in the kidneys are responsible for the filtration of blood and help in excreting waste from the body. They also assist in the production of urine. When the cells in the lining of these tubules start multiplying uncontrollably, it signifies the onset of renal cancer in most of the people.
