Kidney cancer

Most kidney cancers are found by accident on a scan done for something else — and small tumors have excellent outcomes with surgery or ablation.

What to know first

  • The most common type is renal cell carcinoma (RCC), often clear cell.
  • Small (<4 cm) tumors are often treated with partial nephrectomy or ablation, not full kidney removal.
  • Immunotherapy combinations have changed the outlook for advanced disease.

When to see a doctor

  • Blood in the urine, even once
  • Persistent flank or back pain on one side
  • An unexplained mass, fatigue, or weight loss
