Understanding kidney cancer

Cancer is not a single disease with a single type of treatment. There are more than 200 different types of cancer, each with its own name and treatment. This section provides an overview of what cancer is.

  • What is cancer?

    There are more than 200 different kinds of cancer, each with its own name and treatment.

  • About kidney cancer

    About 90% of kidney cancers (9 out of 10) are renal cell cancers. Renal cancer usually only affects one kidney.

  • The kidneys

    Most people have two kidneys. They filter the blood and remove waste products.

  • Signs and symptoms of kidney cancer

    Kidney cancers do not always cause symptoms. Blood in the urine is the most common symptom.

  • Why do cancers come back?

    Sometimes, tiny cancer cells are left behind after cancer treatment. These can divide to form a new tumour.
