Colorectal cancer staging

The treatment of colorectal cancer depends on the stage of the disease. The staging of a carcinoma has to do with the size of the tumour and the degree to which it has penetrated:

  • When the tumour is small and has not penetrated the mucosal layer, it is said to be stage I cancer.
  • Stage II tumours have penetrated into the muscle wall.
  • Stage III involves nearby lymph nodes.
  • The rare stage IV cancer has spread (metastasized) to remote organs.
