How long a tumor can live with tracheal compression depends on the degree of compression, the size of the trachea and the symptoms caused. Squamous lung cancer is mostly central lung cancer, which often compresses the large trachea and causes patients to have difficulty breathing. Without aggressive treatment, patients may not survive for more than a few weeks and will eventually die of respiratory failure. If fast-acting treatments such as radiotherapy and surgery are used, they can only save the patient’s life so that he or she can live for a long time and have a chance to be cured. In the case of squamous lung cancer that invades large blood vessels and causes blood vessels to rupture and bleed resulting in massive hemoptysis, the patient’s chances of surviving are very small and the vast majority will die of asphyxia within hours. In other cases, the mass compresses the trachea and causes obstruction, leading to obstructive pneumonia, which can also cause death from infectious shock within a few weeks if not treated properly. Like lung adenocarcinoma mostly located in the periphery of the lung, the compression is relatively small trachea, which has little impact on lung function and the patient can usually survive for a long time. However, if it leads to a very serious lung infection, coupled with poor treatment and poor outcome, it can also cause the patient to die from infection and respiratory failure within a few weeks.
