The scope of surgical resection for invasive lung adenocarcinoma is the lobes of the lungs and regional lymph nodes in the cancerous area of the patient, but in the treatment of the disease, it is necessary to ask the doctor whether it is possible to carry out the surgical treatment, so that he or she can analyze it in the light of the condition of the disease. If the patient has invasive lung adenocarcinoma but has not metastasized to distant places, and the patient’s cardiopulmonary function and physical fitness are relatively good, surgical treatment can be performed. Resection of the part of the lung lobe that produces cancerous tissues to avoid spreading of cancer cells and also cleaning of the regional lymph node area to avoid metastasis through lymphatic channels can appropriately improve the survival rate of patients. Besides the above areas, if lung adenocarcinoma involves other areas, resection may also be needed, which varies from person to person. After surgical resection, patients should pay attention to rest, do not do strenuous activities, and avoid intake of stimulating food such as onion, sharp pepper, etc. Otherwise, the wound recovery may be slow due to inflammation, meanwhile, patients should cooperate with doctors for regular review.
