There is no specific standard for how long it takes for benign ground-glass nodules to disappear. 1. Most of the benign MG nodules are caused by inflammation and edema due to lung infections, which can disappear within 2 weeks with anti-infective treatment. 2. Benign ground-glass nodules, if the patient does not have symptoms, can be absorbed and disappear within 3 months after increasing the body’s resistance without treatment. 3. A small number of tumor-like benign ground-glass nodules may not disappear on their own, and cancer may not be ruled out in the late stage of benign ground-glass nodules that have existed for a long time. How long does it take for benign ground-glass nodules to disappear is recommended to go to the hospital for further consultation.
