Kidney cancer

Kidney cancer (or renal cancer) is cancer that starts in your kidneys. Your kidneys are 2 bean-shaped organs that filter your blood to remove extra water, salt, and waste products. Your kidneys turn waste into urine.  

​

Different types of kidney cancers can act differently and may need different treatments.

 

Renal cell carcinoma (RCC) is the most common type of kidney cancer. There are 2 main subtypes of RCC:

  • Clear cell RCC – This is the most common type of RCC. It is called clear cell because the cancer cells look very pale or clear under a microscope.

  • Non-clear cell RCC – This includes other types of RCC that are not clear cell.
