Active surveillance for kidney cancer

Active surveillance means closely watching a small kidney tumour that is not causing symptoms.

Understanding the approach

This approach means not treating the tumour right away. Instead, your team checks it often with regular imaging scans  to see if it grows or changes over time.

This chapter contains general information about monitoring kidney cancer. It is not a substitute for professional medical advice or treatment. Always consult your doctor or healthcare provider for guidance on your individual medical situation.
