Whether right central lung cancer is serious or not is closely related to whether the patient is detected early and whether radical surgery can be performed. If right central lung cancer can be treated surgically and no distant metastasis occurs, the prognosis is relatively optimistic. Once distant metastasis occurs, including lymph node metastasis in the neck and liver metastasis, the prognosis is relatively poor if surgery cannot be performed, and patients can only be given radiotherapy, chemotherapy or other treatments. If the cytological classification suggests adenocarcinoma and the gene targeting test is positive, the patient can be treated with gene targeting drugs, and the survival period is relatively optimistic and can be extended for more than one year. In conclusion, all right lung central lung cancers are more serious, have less chance of surgical resection compared to peripheral lung cancers, are prone to distant metastases, and have a poor prognosis. Early detection and early treatment by giving fiberoptic bronchoscopy and chest enhancement CT examination are needed for a more optimistic outcome.
