Lung disease is not a single type, there are inflammation, tuberculosis, tumors, fibrosis, interstitial lesions, etc. Some of these lesions have increased foci and can be recovered, but some are irreversible damage and cannot be recovered. When inflammation occurs in the lungs, and the inflammation is not controlled, the foci of the lungs will increase in size, but after active anti-infection treatment, such as oral or intravenous injection of penicillin or cefoperazone antibiotics, the inflammation will slowly get better, and the foci of the lungs will recover after the inflammation improves. However, when silicosis, interstitial changes, pulmonary fibrosis and other such lesions occur in the lungs, they cannot be recovered, because these lesions will damage the lung cells, and the cell damage cannot be recovered, resulting in permanent damage to the lungs, which cannot be recovered. In this case, it is important to avoid infections in daily life. If you find an increase in the number of lesions, you need to actively seek medical treatment and follow the doctor’s instructions to promote recovery.
