Chinese medicine cannot be used to cure squamous lung cancer, but it can be used according to the identification of evidence for the adjuvant treatment of squamous lung cancer to alleviate the symptoms of the disease. Lung squamous carcinoma is also known as squamous epithelial cell carcinoma of lung, and its treatment is mainly through western medicine at present, and its main treatment methods are surgery, radiotherapy, chemotherapy, etc. Surgery is the main treatment in the early stage, radiotherapy is the supplementary treatment, and chemotherapy is the main treatment in the late stage, and surgery and radiotherapy are the supplementary treatments. Although traditional Chinese medicine cannot cure squamous lung cancer, it has better effects in postoperative recovery, reducing side effects of radiotherapy and improving patients’ survival quality, so it can be used in adjuvant treatment of squamous lung cancer. Patients diagnosed with squamous lung cancer should go to the hospital as soon as possible and follow the doctor’s instructions under the guidance of professional doctors, and do not blindly deal with it on their own, so as to avoid damaging the body and aggravating the condition.
