Recovery after total excision of one side of the breast is usually 4 to 6 weeks, and may be extended to 6 to 8 weeks in case of post-operative infection. The breast is a separate organ and tissue, not an internal organ, and the incision site is located on the torso, so the recovery after total mastectomy is relatively fast. Under normal circumstances, the patient can remove the drainage tube in 1~3 weeks, and the stitches can be removed in 3~4 weeks. After removing the stitches, the patient needs to carry out rehabilitation training on the affected side, and generally, the patient can fully recover in 4~6 weeks, and can lead a normal life and work. However, if infection occurs after total excision of one breast, or fluid accumulates under the breast skin, or the breast skin flap heals poorly, necrosis, etc., the recovery period may be extended to 6-8 weeks. After total excision of one side of the breast, patients should strictly follow the postoperative precautions to avoid the occurrence of wound dehiscence, blood on the wound and fluid accumulation due to local braking or activities, and consult the doctor in time if there is any physical discomfort.
