Total breast cancer excision surgery takes about 1 to 4 hours, depending on the patient’s condition. Total excision surgery for breast cancer includes unilateral excision and bilateral excision, and the surgery includes preoperative preparation, anesthesia, excision of breast tissues and hemostatic bandage, suture, etc. If all the breasts are removed unilaterally, the operation time at this time may be 1 to 2 hours, and if total excision of both breasts is carried out, the operation time and difficulty will increase, and it may take 3 to 4 hours. In addition, if lymph nodes or other tissues are also removed, the operation time will be relatively longer. The duration of total mastectomy is also affected by the patient’s specific condition, physical condition during the operation and other factors. After total breast cancer excision surgery, patients should pay more attention to rest, regular routine, and observe the vital signs, and inform the doctor in time if they feel unwell.
