The main treatment is surgery to remove the affected kidney. We have two kidneys and people can live perfectly well with the one remaining kidney. In a few cases, where the tumour is very small, it is possible to remove only part of the affected organ. If the cancer has spread outside the kidney, the surgeon may remove other tissue. In some cases, when the tumour is too large to remove, the surgeon may block off the blood flow to the tumour, which will cause it to shrink. In some cases, radiation treatment will be used in addition to, or even instead of, surgery. In some cases, treatment with hormones, interferon or interleukin can be used.
