Whether the actual lung lesions can be cured cannot be generalized, but depends on the cause of the actual lung lesions, the size of the actual lung lesions, the degree of the disease, and the patient’s resistance to a comprehensive assessment, as follows: a. If the actual lung lesions are caused by lung infections, such as bacteria, viruses, mycoplasma, chlamydia and other pathogenic microorganisms infecting the lungs and causing the actual lung lesions. In this case, as long as the treatment is timely, coupled with the patient’s resistance is relatively good, generally can be cured. If the treatment is late, and the infecting pathogenic microorganisms may be drug-resistant, that is, not sensitive enough to the existing anti-microbial drugs, or the patient’s resistance is poor, in this case, it may also gradually aggravate and not be able to cure. Patients with pulmonary tuberculosis can be cured as long as they have good resistance and can be treated regularly, but old lesions, such as calcified foci, may remain in the lungs after cure. If it is an in situ lung malignancy without metastasis, it may be cured after surgery, but if metastasis occurs, it cannot be cured in this case.
