A rotted TB lung is usually treatable. If a person with tuberculosis has a broken lung, but it is not too severe, it can be treated. However, if the breakage is severe and severe necrosis has occurred, it usually cannot be repaired. If a TB patient’s lung is slightly damaged, as long as he or she receives timely anti-tuberculosis treatment, and also needs sputum treatment and nutritional support, the lesion can be gradually reduced in size and may eventually return to normal. If the patient’s lungs are severely necrotic, or there are symptoms such as lung cavities, calcification, nodules and so on. At the same time, the patient’s immunity is low, at this time, surgical treatment is needed, if the treatment is not timely, the disease may also gradually deteriorate. If a patient with tuberculosis has rotten lungs, it is recommended to go to the hospital in time for diagnosis, so that a professional doctor can make a judgment and give a suitable treatment plan.
