After surgery for atypical hyperplasia of the lungs, a one-month follow-up examination is needed, mainly to observe the recovery of the surgical area and the condition of the lungs, and to find abnormalities that can be dealt with in a timely manner, followed by regular annual follow-up examinations. Atypical hyperplasia of the lungs belongs to pre-cancerous lesions, and most of them can be clinically cured after radical resection through surgery. One month after the operation, the patient should have a follow-up examination, mainly to check the condition of the lungs and the chest cavity. Generally speaking, the recovery condition is good, and then the patient should have a regular annual follow-up examination of CT of the lungs. If there are obvious symptoms such as breath-holding and chest tightness during the postoperative recovery period, it is necessary to consult a doctor in time for observation, to clarify the specific condition through CT examination, and to deal with the abnormality in time, so as to avoid delaying the condition.
