Renal cell carcinoma (RCC) is one of the most common types of kidney cancers seen in adults. RCC occurs more often in men between the ages of 50 to 70. The kidneys help get rid of waste in the body. There are small tubes in the kidneys that help filter waste from the blood and help make urine. RCC occurs when cells start growing uncontrollably in the lining of these small tubes. Symptoms may not appear in the early stages of renal cell carcinoma, which is why renal cell carcinoma is normally advanced when found. Later symptoms may include blood in urine, a lump in the abdomen, weight loss, anemia, and loss of appetite. If untreated, it may spread to the lymph nodes, lungs, liver, adrenal glands, brain, or bones.
