Breast surgery usually requires axillary lymph node dissection, and lifting heavy objects after surgery may cause slow wound healing, upper extremity edema, local wound infection and other hazards. 1. Slow wound healing: After breast surgery, you can’t lift heavy objects because the body recovers slowly after surgery, and the body is relatively weak, if you lift heavy objects after surgery, it will increase the pain of weight-bearing and the possibility of pulling to the wound, which is not conducive to wound healing. 2. Upper extremity edema: breast surgery usually requires axillary lymph node dissection, due to the destruction of the normal structure, resulting in lymphatic reflux obstruction, swelling of varying degrees, if the postoperative lifting heavy objects may aggravate the lymphatic reflux obstruction, resulting in aggravation of upper extremity edema. 3. Local wound infection: lifting heavy objects after surgery may cause local wound cracking, and if bacteria invade, local wound infection or even hemorrhage and necrosis may occur. It is suggested that patients should take rest and recuperate after surgery, avoid lifting heavy objects too early, and go to the hospital in time if there is any discomfort, so as to avoid serious illness and other damages.
