After breast cancer surgery, it is recommended to eat more foods that are easy to digest and absorb, soup foods such as thin rice, noodles, fish soup, vegetable soup, fruit juice, etc. You can also eat rice and pasta, but you cannot eat spicy and stimulating foods, and you should also avoid eating foods with too much oil and meat. Eating spicy and stimulating food will lead to gastrointestinal discomfort, bloating and diarrhea, etc. Eating overly oily and heavy food will lead to diarrhea and may also cause patients to have lymphatic fistula. Some breast cancer patients may have lymphatic fistula after surgery. Patients with lymphatic fistula should have a light diet in their normal life, and if they eat too much meat and oil, the lymphatic fluid will leak very much.
