Kidney cancer staging
After a kidney cancer diagnosis, we use a series of tests to understand the cancer’s stage. Staging helps us record the size, aggressiveness, and growth of a cancer. It also helps us determine the best plan for treatment.
Kidney cancer staging helps doctors understand if and how much the cancer has spread. It also gives doctors a common language for describing tumors.
Staging helps us:
- Figure out the extent of the cancer
- Compare your situation to other patients with kidney cancer
- Review clinical studies to understand how the cancer may behave and how treatments may work for patients in similar stages
- Determine the likely course of the disease (your prognosis)
To stage kidney cancer, we use information gathered from:
- Physical exams
- Blood and urine tests
- Imaging tests, such as CT scans and MRIs
- Procedures such as a kidney biopsy
At Penn Medicine, our pathologists (lab specialists) and radiologists (imaging specialists) are kidney cancer experts. They work to give you a detailed and accurate diagnosis. Their experience with every stage of kidney cancer helps them identify key details that improve treatments.
Kidney cancer has four stages:
- Stage I: The kidney tumor is less than 7 centimeters and has not spread.
- Stage II: The kidney tumor is greater than 7 centimeters and has not spread.
- Stage III: The tumor (any size) is in the kidney and nearby lymph nodes or in the blood vessels and surrounding kidney tissue.
- Stage IV: The cancer has spread to lymph nodes, to other organs, or to the adrenal gland above the kidney.
