Breast cancer patients can exercise appropriately after surgery, but it is worth noting that strenuous exercise should be avoided for 3-6 months after surgery, and some soothing exercises, such as yoga and brisk walking, can be performed. The amount of activity should not be too much, and a slight sweating is appropriate. In the case of patients during chemotherapy for breast cancer, it is recommended that patients exercise 5 times a week, such as jogging for more than 15 minutes each time, because exercise can improve the patient’s resistance and at the same time can help keep the patient’s weight in the normal range and reduce the risk of other complications. However, if axillary lymph node dissection was performed at the time of surgery, the affected limb should be protected, and such patients should not perform exercises of excessive amplitude and magnitude on the affected limb, nor should they lift heavy objects to avoid aggravating the edema of the affected limb. When the patient has recovered well, he or she can do exercises such as jumping rope, swimming and badminton. Patients are recommended to perform at least 150 minutes of aerobic exercise per week, and the intensity of exercise should be gradually increased. Usually patients can gradually restore the basic function of the affected limb to normal after training. In addition to functional rehabilitation exercises, patients should also pay attention to dietary regimen, avoid spicy and stimulating foods, and eat more fresh vegetables and fruits to supplement vitamins and promote recovery.
