Avoid eating hot and scalding food and drinks on the day after surgery. 7. The chest should be bandaged with pressure for 2-4 days after surgery, and patients are required to avoid chest collision and strenuous exercise. If you want to get up to go to the bathroom, you should move slowly and sit up and rest by the bedside for a few minutes before you can go down to the floor. The medication will be changed on the second day of surgery, and a bra will be worn to fix the breast after the fourth day of postoperative medication change and examination, and the patient can be discharged after the completion of postoperative pathological diagnosis. 8.Medically insured patients should be admitted at least 2 days before surgery to complete the preoperative examination and wait for surgery. 9.The results of routine pathology will be available in about 5 days, but in special cases, it will take about a week, so we hope that patients and their families will wait patiently.
