After colon cancer surgery, recurrence can be minimized by regular review, maintaining good living habits and avoiding high-risk factors. 1. Regular rechecking: Due to the high degree of malignancy of colon cancer, recurrence often occurs after surgery. Therefore, it is necessary to follow the doctor’s instruction to have regular checkups, i.e. every 3 months in the first 3 years after surgery; every 6 months in 3~5 years; and every 1 year after 5 years. 2. Maintaining good living habits: After surgery, you should exercise properly in your daily life, do not stay up late, have a regular work and rest schedule, maintain an optimistic mindset, and eat a balanced diet. 3. Avoid high-risk factors: quit smoking, keep BMI within normal range, cure ulcerative colitis and other colon lesions in time. To summarize, after colon cancer surgery, one must follow the doctor’s instructions to improve the quality of survival and prolong the life span.
