If a patient has symptoms that suggest kidney cancer, the doctor may perform one or more of the following procedures:
  • Physical exam
  • Urine tests
  • Blood tests
  • Intravenous pyelogram (IVP)
  • CT scan
  • Ultrasound test
  • Biopsy
  • Surgery
 

Staging

Staging may involve imaging tests such as an ultrasound or a CT scan. The doctor also may use an MRI. For this test, a powerful magnet linked to a computer makes detailed pictures of organs and blood vessels. Following are the stages of renal cancer: Stage I is an early stage of kidney cancer. The tumor measures up to 2 3/4 inches (7 centimeters). It is no bigger than a tennis ball. The cancer cells are found only in the kidney. Stage II is also an early stage of kidney cancer, but the tumor measures more than 2 3/4 inches. The cancer cells are found only in the kidney. Stage III is one of the following:
  • The tumor does not extend beyond the kidney, but cancer cells have spread through the lymphatic system to one nearby lymph node; or
  • The tumor has invaded the adrenal gland or the layers of fat and fibrous tissue that surround the kidney, but cancer cells have not spread beyond the fibrous tissue. Cancer cells may be found in one nearby lymph node; or
  • The cancer cells have spread from the kidney to a nearby large blood vessel. Cancer cells may be found in one nearby lymph node.
  Stage IV is one of the following:
  • The tumor extends beyond the fibrous tissue that surrounds the kidney; or
  • Cancer cells are found in more than one nearby lymph node; or
  • The cancer has spread to other places in the body such as the lungs.
Recurrent cancer is cancer that has recurred after treatment. It may come back in the kidney or in another part of the body.
