Kidney cancer (renal cell carcinoma) originates in one or both of the kidneys – the body’s main filter that is responsible for fluid balance, regulating electrolytes, preventing acid buildup, eliminating waste, producing urine and regulating blood pressure. The kidney also manufactures a hormone responsible for red blood cell production. Symptoms of kidney cancer may include: lower back pain, bloody urine, weight loss, fever and anemia. If kidney cancer is detected and treated early, the survival rate ranges from 79-100%. If the cancer goes undetected, it can often spread and cause complications. Treatment may include removal of the cancerous kidney or chemotherapy and radiation in more advanced stages.
