Kidney Cancer

At MaineHealth, our teams of cancer specialists evaluate and treat patients with all types of kidney cancer. We offer compassionate care and advanced treatment for kidney cancers in adults and children.

What is kidney cancer?

Kidney cancer is a cancer that starts in the kidneys. Abnormal (cancerous) cells form and grow out of control. There are three main types of kidney cancer.

  • Renal cell cancer is the most common kidney cancer in adults. It forms in the kidney tissue that makes urine and is most common in adults

  • Urothelial cancer is an adult cancer that forms in the renal pelvis and ureter.

  • Wilms tumors are more common in children. They also form in kidney tissue that makes urine.
