Generally speaking, after lung cancer patients reach the middle stage of lung cancer, most of them will choose surgery as the treatment method. First of all, for patients with lung cancer, the clinical treatment effect, whether the surgery is complete or not, and the patient’s physical quality greatly affect how long a lung cancer patient can live after surgery, so it is recommended that once the disease is confirmed, the patient should have timely treatment. Therefore, it is recommended that once the disease is confirmed, the patient should be treated promptly. The time of treatment will also affect the postoperative effect, so early treatment is the most important thing to do when the disease is detected. Secondly, the patient’s body constitution has a very important correlation with the effect of treatment. Usually, only if the patient has good health and strong immunity, then he can effectively resist the development of tumor and tolerate various drug treatments. Therefore, it is very important for lung cancer patients to improve their immune function and strengthen their resistance to tumor. Finally, in terms of diet, lung cancer patients should deal with the relationship between diet and the peak time of chemotherapy drug action, avoid eating during the peak period of drug action, and must give sufficient nutrition and rich vitamins to replenish qi and generate blood, and also rely on taking traditional Chinese medicines that have the effects of dissolving phlegm, regulating qi and removing stasis, strengthening immunity, killing cancer cells and inhibiting cancer cell development. In addition, the patient’s emotion and mental state can also interfere with the prognosis, and optimism and cheerfulness are beneficial to the healing of tumor. Therefore, family members and friends should guide the patient more, and usually the patient can do some simple sports to increase physical fitness.
