Ways to prevent cancer recurrence may include regular checkups, maintaining good living habits, etc. The statement of seven tips is slightly absolute. Cancer is a malignant disease caused by a variety of factors, including internal and external factors, and the treatment after diagnosis is a comprehensive treatment based on surgical resection. The important point to reduce the recurrence rate after surgery is to follow the doctor’s instructions for regular checkups, usually every 3 months during the first 1~2 years, every 6 months during the 2~5 years, and every 1 year thereafter.
