Resection of the whole lung of squamous lung cancer is not allowed. Squamous lung cancer will affect the lung function of patients, resulting in poor breathing and breathlessness, etc. Early stage can be resected by surgery, but usually it is localized resection, and for some patients with more serious condition, one side of the lungs can be resected at the site of onset of the disease, but not the left and right sides of both lungs can be resected completely. Once a patient’s lungs are completely removed, they lose their normal respiratory function and are unable to provide enough oxygen to the organs of the body, which can lead to the patient’s death. When encountering advanced squamous lung cancer patients with serious condition, chemotherapy, targeted therapy and other comprehensive treatments are mainly carried out to prolong the survival cycle of patients.
