What is a kidney tumor?

A kidney tumor is an abnormal growth within or on the kidney. Kidney tumors may be benign (non-cancerous) or malignant (cancerous, also known as renal cell carcinoma).

Many kidney tumors are found incidentally during imaging for other conditions. Treatment depends on the size and characteristics of the tumor.
