Carbuncle is not lung cancer. Lung carbuncle is a term in Chinese medicine, which is mainly caused by lung infection and abscess. It is a benign disease and can be improved after timely anti-infection and anti-inflammatory treatment. Lung cancer, on the other hand, is a malignant disease, which is related to factors such as prolonged inflammation stimulation and living environment, and is prone to metastasis and proliferation, which makes it more difficult to treat. Generally speaking, only early stage lung cancer patients can have a chance to be cured and recovered by timely radical surgery; for middle and late stage patients, radiotherapy, chemotherapy, targeted therapy and other comprehensive treatments are mainly used to prolong the survival period and improve the quality of life, and it is difficult to realize the recovery.
