Whether or not lung solid lesions can be completely cured needs to be evaluated comprehensively according to the cause of lung solid lesions, the size of lung solid lesions, and the patient’s resistance. 1. If the lung solid lesion is caused by lung infection, such as bacteria, virus, mycoplasma, chlamydia and other pathogenic microorganisms. In this case, as long as the treatment is timely and the patient’s resistance is relatively good, it can usually be completely cured. If the treatment is late or the patient’s resistance is poor, it may lead to gradual aggravation of the symptoms and not be cured. 2. If the solid lung lesion is caused by tuberculosis bacillus invading the lungs, under the guidance of specialists, taking anti-tuberculosis drugs at an early stage, in combination, throughout the whole process, in the right amount, and in a regular manner, the solid lesion can be absorbed and improved. 3. Cardiogenic pulmonary edema, pulmonary embolism, acute respiratory distress syndrome, etc. can also lead to solid lesions in the lungs, and a better prognosis can generally be achieved if timely treatment is provided for the primary disease. However, due to the possible complications of the disease itself, or the severity of the disease, delayed treatment, etc., there may be a situation in which the disease cannot be completely cured. Patients with solid lung lesions should seek medical attention as soon as possible and actively cooperate with their doctors to avoid delays in treatment.
