Squamous carcinoma mainly manifests as central lung cancer, and the location is generally central. Nowadays, the main clinical treatment measures include radiotherapy and chemotherapy, and the specific plan should be decided according to the stage of the tumor. The efficacy of radiotherapy and chemotherapy is determined according to the patient’s specific symptoms, history of smoking and genetic factors, etc. The specific situation is analyzed. Since squamous lung cancer is particularly close to large blood vessels, it is generally difficult to do surgery, if surgery is not possible, radiotherapy or chemotherapy is recommended. For some patients with relatively poor symptoms, such as poor liver and kidney function, radiotherapy is recommended; if the liver and kidney function is good, the general condition is good and the lesion is not large, chemotherapy can be adopted.
