In addition to regular medical checkups, even advanced lung cancers can be treated with comprehensive treatment to improve the quality of life. The following issues need attention! Palliative care The purpose of palliative care is to relieve symptoms, relieve pain and improve quality of life. All lung cancer patients should be screened, evaluated and treated for symptoms throughout the course of palliative medicine. The symptoms to be screened include both common physical symptoms such as pain, dyspnea, and fatigue, and should also include psychological problems such as sleep disturbance and anxiety and depression.

Morphine and its similar drugs are commonly used in cancer pain treatment, and addiction is rare; analgesic treatment should be carried out under the guidance of medical staff, and patients should not adjust the treatment plan and drug dose by themselves; they should closely observe the efficacy and side effects of drugs, communicate with medical staff at any time, and follow up regularly.
