Why is it necessary to rehabilitate the affected limb after radical breast cancer surgery? With the development of treatment methods, the cure rate and survival rate of breast cancer are increasing, and the majority of patients are not satisfied with just saving their lives, the quality of survival after treatment is highly valued. The dysfunction of the affected upper limb often occurs after radical breast cancer surgery, which leads to the inability to take care of oneself and causes great physical and psychological pain to the patients. Active rehabilitation after radical breast cancer surgery can effectively restore the function of the affected limb, reduce patients’ physical and mental pain, enhance their confidence in life, and return to their families and society as soon as possible. What are the main reasons for the dysfunction of the affected limbs? Postoperative scar contracture of the incision and axilla and lymphatic edema caused by the destruction of lymphatic tissue and the obstruction of lymphatic fluid return are the two main reasons affecting the function of the affected limb. Why can rehabilitation therapy improve the function of the affected limb? In systematic rehabilitation treatment, gradually increasing the mobility of the affected limb can effectively reduce the scar contracture of the patient’s affected incision and axilla, and strengthen the muscle strength, so that the function of the affected limb can be restored to different degrees. Many patients have lymphatic edema similar to “rubber swelling” due to lymphatic reflux obstruction, and even epidermal dermatitis-like inflammation of the affected limb, resulting in swelling, pain and limitation of movement of the affected limb, which seriously affects the quality of life of patients. Rehabilitation exercises can promote blood circulation and lymphatic reflux, thus effectively preventing and reducing the occurrence of edema in the affected limbs. Specific methods of mammary gland rehabilitation therapy On the first postoperative day, patients are instructed to perform early rehabilitation exercises such as freehand exercises; on the eighth postoperative day, when the drains are removed and no subcutaneous fluid accumulation occurs, patients are instructed to use rehabilitation equipment to gradually perform joint exercises and muscle strength exercises starting from finger joints to elbow joints and shoulder joints; from the twelfth postoperative day, on the basis of freehand exercises and equipment exercises, patients are instructed to From the twelfth day after surgery, the patient was instructed to systematically perform comprehensive musical rehabilitation exercises to strengthen the movement of the affected limb at all angles, exercise the synergistic muscles, enhance the function of the affected limb, accelerate blood circulation and promote lymphatic flow. We have randomly selected 100 patients for observation and study, and the results show that after rehabilitation, the function of the affected limb has improved significantly, 70% of the patients can approach or reach the normal function before surgery, and can basically take care of themselves. Patients who did not have systematic rehabilitation exercise had unsatisfactory functional recovery of the affected limb after surgery, which was significantly worse than the rehabilitation group and affected work and life.
