The maintenance after minimally invasive breast nodule surgery should first pay attention to the compression bandage, keep the wound clean and dry, and avoid strenuous exercise and eat a light diet. Post-operative care should first pay attention to the pressure bandage to compress and stop bleeding to prevent the emergence of local tissue hematoma. Surgical wounds are regularly changed and sterilized to keep the wounds clean and dry. Avoid squeezing and collision of the chest for one week after surgery, and avoid internal bleeding and hematoma of the wound caused by strenuous exercise. Meanwhile, patients should have a light diet during the postoperative recovery period, avoid spicy and stimulating food, and have regular rechecks. If there is any pain in the wound or hard lumps in the breast, patients should seek medical treatment in time. Minimally invasive breast nodule surgery has small incision and less bleeding, so the recovery after surgery is faster. Under good care, the wounds will heal in one week, and the internal tissues will fully recover in about three weeks, so the patient can return to normal life and work.
