Your arm will be swollen and impaired in movement after surgery, and radiation therapy will increase the likelihood of arm swelling, and edema will appear for months to years after surgery. An effective solution is to engage in early physical therapy by doing stretching exercises such as climbing the wall of the affected arm and stretching to the threshold of pain. With such persistence for a few weeks, the mobility of the skin can be greatly improved. During and after radiotherapy, it is important to keep exercising every day to ensure that the skin, or even the entire shoulder, maintains its current state of skin mobility or returns to its optimal state. In general, bathing is allowed once the wound has healed and scabbed over; it facilitates recovery. If after a phase of radiotherapy, it is important to avoid contaminating the wound by bathing when the skin has a wet reaction such as oozing. The water temperature of bathing should not exceed 37℃ to 38℃. Soap or soap-like items can irritate the skin, especially the skin on the scar and under the armpit is more sensitive, so it is better to use it sparingly or not. Perform functional exercise of the affected limb after surgery when training for rehabilitation 1-2 days after surgery practice fist clenching, finger extension, and wrist flexion; 3-4 days after surgery, forearm flexion exercise; 5-7 days after surgery, the hand on the affected side touches the opposite shoulder and the ipsilateral ear; 8-10 days after surgery, practice shoulder joint elevation, extension, and flexion to 90 degrees. After 10 days postoperatively, shoulder joint climbing wall and apparatus exercises were performed. After getting up and moving around, do functional exercises according to the specific situation. Fourteen days after surgery, the affected limb can go around the top of the head to touch the opposite side of the ear. The functional exercise of the affected limb should be noted: restrict the shoulder joint activity within 7 days after surgery to avoid affecting the healing of the skin flap. Reduce the number of exercises in case of subcutaneous fluid accumulation. Breast cancer patients should eat more fresh vegetables and fruits, less red meat, and keep consuming 200-300 grams of vegetables and 100 grams of fruits every day, such as cabbage, pumpkin, garlic, carrot, cabbage, string beans, tomato, eggplant, asparagus, shiitake mushroom, sea cucumber, kelp, apple, white pear, banana, umeboshi, citrus pick, etc. It can enhance the anti-cancer ability and can reduce the recurrence rate of breast cancer. More moderate amount of sugar can be consumed to supplement calories. Patients with high-dose radiation therapy can have their body’s sugar metabolism destroyed, glycogen drops sharply, lactic acid in the blood increases and cannot be reused; and insulin deficiency is aggravated. So it is better to supplement glucose. In addition, it is advisable to eat more sugar-rich food such as honey, rice, noodles and potatoes to supplement calories. Post-operative review should be done by oncologist on time, within 2-3 years after surgery, every 3 months, thereafter it can be done every 6 months. What are the items to be examined? First of all, the doctor needs to check the body and palpate the lymph nodes on the affected side, contralateral breast, armpit and clavicle. Depending on the condition, some patients will also have a chest x-ray, abdominal ultrasound, and bone scan. Based on the results of each of these tests, a decision will be made as to whether further testing is necessary.
