Kidney cancer, also known as renal cancer, originates in the kidneys, which are vital organs responsible for filtering waste and excess fluid from blood. Symptoms include blood in urine, abdominal pain, lumps in the abdomen, sudden weight loss and extreme fatigue. Treatment for kidney cancer depends on the stage of the disease. If it is confined to the kidney, a nephrectomy (kidney removal) is performed, or a removal of the tumor (partial nephrectomy) is done. This surgery can be performed through a small incision. If the kidney cancer has spread beyond the kidney, other treatment options are available. Your doctor will perform a thorough workup to determine what plan of care is best for you.
