When diagnosed with lung cancer, one should follow the doctor’s prescription for treatment in time. Doctors will provide comprehensive and individualized treatment according to the type of case and clinical staging of the patient, and the commonly used treatments include surgery, chemotherapy and radiotherapy. Early stage lung cancer can be treated with surgery such as lung resection and segmental lung resection through open thoracotomy or thoracoscopic surgery. Patients with advanced lung cancer can stop the growth of cancer cells through oral and injected chemotherapy drugs, and the commonly used chemotherapy drugs include cisplatin, gemcitabine, docetaxel and so on. Patients with small cell lung cancer can use radioactive high energy beams to kill the cancer cells. As for patients with non-small cell lung cancer, targeted drugs can be used to kill cancer cells, and commonly used drugs include afatinib, crizotinib, bevacizumab, and cetuximab. In addition, the use of immunotherapy such as nabumab and pembrolizumab is also effective in prolonging the survival of advanced lung cancer patients. When diagnosed with lung cancer, patients should follow the doctor’s prescription and standardize the treatment in time. In addition, patients should adjust their emotions and face the disease with a positive mindset, and at the same time, they need to improve their life style, such as quitting smoking and exercising appropriately. The above drugs should be used under the guidance of professional physicians.
