 Hello, I am Dr. Kapoli Lahkar, consultant medical oncologist in Manipal Hospital, Bangalore. Colon cancer in most cases is a curable disease. The 5-year survival in stage 1 is more than 90%. In stage 2, depending on the particular subtype of stage 2, it can vary between 60-80%. In the third stage, it varies between 50-70% and even in the fourth stage or in the metastatic stage, around 10-12% of patients can be cured. So it is imperative to consult a doctor and take adequate treatment in oral cancer. It is a highly curable disease.
