The survival time of patients with hemoptysis of lung cancer is broadly divided into 2 kinds of situations: 1. It is this typical massive hemoptysis, which is at an advanced stage of lung cancer, when the tumor has invaded the large blood vessels, allowing them to break down and cause bleeding. Patients with massive hemoptysis often may not even live for 1 month. Because of frequent massive hemoptysis, the patient eventually suffocates, suffers from rapid respiratory failure and dies due to the large amount of bleeding. Once such large hemoptysis occurs, the survival time of the patient may be 5 minutes or even half an hour. 2. However, if effective treatment or small hemoptysis, that is, a small amount of blood in the sputum, is early central lung cancer, it can be controlled effectively through radiotherapy and chemotherapy, and then the tumor can regress and the blood vessels can be repaired. It is possible that the patient can survive for a long time, 2-3 years or even be completely cured, so it should be treated differently.
