Lung squamous carcinoma is usually treated by surgery, radiotherapy and chemotherapy, and medicines should be used according to doctor’s instructions. 1. Squamous lung cancer can be treated by surgery, and the commonly used surgical method is lobectomy with lymph node dissection, which also includes total pneumonectomy, compound lobectomy, etc. Squamous lung cancer usually grows slowly and develops metastasis at a later stage. Generally, squamous lung cancer grows slowly and metastasis occurs at a later stage. Surgical treatment is safer and can achieve radical resection of tumor with greater probability and clear the internal lymph nodes of patients. 2. Radiotherapy, short for radiation therapy, is to irradiate the tumor internally or externally by radiation (such as X-ray, γ-ray, etc.), so as to reduce the size of the tumor to provide opportunities for surgery, or to kill the tumor tissue. 3. Chemotherapy, short for chemical drug treatment, is commonly used to carry out chemotherapy with drugs such as vincristine and paclitaxel, so that the drugs can enter into the bloodstream and be transported to various parts of the body to achieve the therapeutic purpose of killing cancer cells and inhibiting their metastasis. It is suggested that patients with squamous lung cancer should go to regular hospitals in time and listen to the advice of professional doctors.
