One week after breast cancer surgery can resume normal diet. For breast cancer patients, surgery on breast and chest wall will not affect the function of patient’s gastrointestinal tract. On the first day after surgery patients can resume diet, including liquid and semi-liquid food, they can eat thin rice, noodles, fish soup, etc. On the 2nd-3rd day they can transition to normal diet, including rice, pasta, etc. However, breast cancer patients are prone to have lymphatic fistula, so it is recommended to eat as light a diet as possible with less fats and oils. One week after surgery, patients can be discharged from the hospital. Basically, patients can have a normal diet at home, including rice and noodles, and at the same time, they can eat more fresh vegetables and fruits, stir-fry and roasted vegetables, apples and bananas, etc. There is no problem.
