Squamous carcinoma of the lung is more malignant. Squamous cell carcinomas have different degrees of differentiation, slow growth, and long course. When the mass is large, central necrosis and thick-walled cavity may appear. Common clinical manifestations of squamous cell carcinoma of lung are fever, cough, chest pain, etc. X-ray examination can find out the specific location and approximate volume of squamous cell carcinoma of lung, and bronchoscopy can determine the specific lesions in the endobronchial tubes and lumen. Surgery is preferred for squamous lung cancer. Postoperative radiotherapy or chemotherapy can be supplemented according to the pathology. Synchronized radiotherapy may be used for advanced tumors. Chemotherapy suppresses the hematopoietic system in the bone marrow. Note the reduction of white blood cells and platelets, and squamous lung cancer can be treated with granulocyte colony-stimulating factor and platelet-stimulating factor. If patients are diagnosed with squamous lung cancer, it is recommended to go to regular hospitals in time, follow the advice of specialists to standardize diagnosis and treatment, and follow up regularly.
