Renal Cell Cancer Treatment (PDQ®): Treatment - Patient Information [NCI] - Stages of Renal Cell Cancer
The metastatic tumor is the same type of cancer as the primary tumor. For example, if renal cell cancer spreads to the bone, the cancer cells in the bone are actually cancerous renal cells. The disease is metastatic renal cell cancer, not bone cancer.
The following stages are used for renal cell cancer:
Pea, peanut, walnut, and lime show tumor sizes.
In stage I, the tumor is 7 centimeters or smaller and is found only in the kidney.
In stage II, the tumor is larger than 7 centimeters and is found only in the kidney.
In stage III:
- the tumor is any size and cancer is found only in the kidney and in 1 or more nearby lymph nodes; or
- cancer is found in the main blood vessels of the kidney or in the layer of fatty tissue around the kidney. Cancer may be found in 1 or more nearby lymph nodes.
In stage IV, cancer has spread:
- beyond the layer of fatty tissue around the kidney and may be found in the adrenal gland above the kidney with cancer, or in nearby lymph nodes; or
- to other organs, such as the lungs, liver, bones, or brain, and may have spread to lymph nodes.
