Lung cancer is more likely to occur in the elderly, so it is also found in the clinic at the age of 80. For elderly people, it also depends on the physical condition of the patient. If the cardiopulmonary function is tolerable and the lung cancer lesion itself is not large enough to be treated surgically, surgery can be performed, but the risk of surgery is much higher compared with other people of younger age. If the patient is not in good physical condition and has more underlying diseases and cannot tolerate surgery or force surgery, palliative radiotherapy or chemotherapy can be considered to control the disease. If there is a mutation in the genetic test, you can consider treatment with targeted drugs, which are used for 80-year-olds.
