    Initial treatment is most commonly either partial or complete removal of the affected kidney(s). [4] Where the cancer has not metastasised (spread to other organs) or burrowed deeper into the tissues of the kidney, the five-year survival rate is 65–90%, [ 5 ] but this is lowered considerably when the cancer has spread.
