How long a person can live with a few pulmonary fibrotic foci depends on his or her condition. If the patient’s disease develops slowly, the survival time will be longer, if the patient’s disease develops faster, the patient’s survival time will become shorter. The appearance of the disease should be actively treated, so as to prolong the survival period. Patients with pulmonary oligofibrotic foci only have inflammation, and the disease develops slowly, and the patient is also actively undergoing treatment, so that the survival time of the patient is longer; if the patient appears to have pulmonary oligofibrotic foci at the time of diagnosis of both lungs diffuse, may affect the respiratory function, and then the survival time may be about 3 years to 5 years. The survival time of patients with pulmonary fibrotic lesions is also based on whether the patient eliminates the cause of the disease. If the patient is unable to get rid of the environment or habits that lead to pulmonary fibrotic lesions, the disease may develop further and the survival time will be shortened; there are many factors affecting pulmonary fibrotic lesions, such as smoking, exposure to dust, etc. If the patient is able to get rid of the environment or quit smoking, and actively treats the foci of the infection, he or she will prevent further progression and the survival time will be lengthened. Further development and survival will be prolonged. It is recommended that when the disease occurs, active treatment, but also to pay attention to the treatment of the disease.
