Immunotherapy, such as the use of drugs such as navulizumab to identify and kill tumor cells, is suitable for patients who have failed chemotherapy. Targeted therapy targets lung cancer patients with gene mutation, and commonly used drugs include gefitinib and so on. 2. Surgery: If the tumor is in the early stage, it can be treated by surgically removing the tumor tissue. 3. Radiation therapy: killing tumor cells through radiation, often combined with chemotherapy. 4. Interventional therapy: for patients who cannot undergo surgery or chemotherapy, interventional therapy can be used to block the blood vessels of the tumor and alleviate the symptoms of the tumor. If the right lower lung tumor is diagnosed, it is recommended that patients go to regular hospitals in time and listen to the advice of professional doctors.
