Surgical treatment is the first and main treatment method for lung cancer, but post-surgery does not mean that the tumor is cured, so we should actively take care of it to prevent recurrence and metastasis. After surgery, we should pay attention to the following points: 1. Avoid contact with factors that cause lung tumor, such as smoking or pollution in the environment, which should be avoided as much as possible; 2. In the rehabilitation phase, we should insist on exercising every day, you can play taijiquan and do Bada Jin, which can better restore lung function; 3, in terms of dietary care, we should have a balanced diet to ensure the supply of the body, without deliberately supplementing certain foods in large quantities. Diabetic patients in the process of eating, avoid too harsh diet, you can control the diet is not too much, but nutritious, and should be well absorbed and easy to digest; 4, postoperative patients need to avoid colds, because once the cold will be a systemic decline in immune function, which is very detrimental to the disease; 5, pay attention to regular review, the first year after surgery every three months, the second year after surgery every six months, after surgery After three years, we emphasize to review once a year. In this way, we can understand the general condition of the tumor, and we can also review some parts of lung cancer that often metastasize, mainly lung, liver, bone, brain and other organs, so as to understand the hidden danger of the tumor and try to exclude it.
