Is it possible for late stage colon cancer be cured?

Stage 4? If by late you mean stage 4 (metastatic), the answer is: possible but unlikely. If the number of metastases is limited and the patient is in good shape, he/she could be treated aggressively with surgery and chemo (maybe even radiotherapy) and some of those, God willing, can be cured. I have seen a few of such patients and I'm sure my colleagues here have too. Best wishes. .
