Some early and middle stage pneumonic lung cancer patients can choose surgery, but surgery is generally not recommended for advanced stage patients, and doctors need to formulate a treatment plan according to the specific conditions of the patients. For early stage lung cancer patients, the cancer cells have not yet spread, so if they meet the conditions for surgery, they can usually follow the doctor’s instructions to undergo surgery to completely remove the lesions, and most of the patients do not need to undergo adjuvant radiotherapy after the surgery. However, some early-stage patients are not suitable for surgery and can choose radical radiotherapy. For middle stage lung cancer patients, according to the condition of tumor lesions, they can undergo surgery and have adjuvant radiotherapy after surgery, or choose neoadjuvant chemotherapy and then surgery. Most patients with advanced lung cancer have missed the best time for surgery, so they can choose palliative radiotherapy and chemotherapy, and some of them can apply targeted drug therapy or immunotherapy according to the results of genetic examination. At the same time, symptomatic supportive treatment is needed, such as giving patients oxygen therapy when they have difficulty in breathing, and giving patients oral drugs such as ambroxol hydrochloride, acetylcysteine and other cough and phlegm relieving drugs when they cough. It is recommended that patients with pneumonic lung cancer should go to regular hospitals for timely consultation, follow the specialist’s advice, standardized diagnosis and treatment, and regular follow-up to avoid missing the best treatment time.
