Lung cancer patients should avoid infection, strenuous activities and bad life style after surgery. 1. Avoiding infection: if patients use traditional surgery for lung cancer treatment, there is a big incision after surgery, patients should avoid infection of the incision. Meanwhile, after the operation, the lung function is poor, so patients should pay attention to avoiding lung infection. 2. Avoid strenuous activities: lung cancer patients should avoid strenuous exercise after surgery. On the one hand, strenuous exercise may crack the wound, etc. On the other hand, as the lung function of patients is poor after surgery, strenuous exercise may lead to respiratory difficulty or even asphyxiation. 3. Avoid bad life: patients should pay attention to ensure good life style after operation, don’t smoke and drink alcohol, don’t eat stimulating and spicy food, and at the same time, ensure nutrition supply, which can effectively promote wound healing. Lung cancer patients should have regular review after cure to avoid recurrence of the disease.
