(1) Eat high-calorie and high-carbohydrate foods, because a high-carbohydrate diet can provide enough calories for breast cancer patients, reduce protein consumption and prevent hypoglycemia; Can protect liver cells from anesthesia damage; It can also increase the body's resistance to make up for the calorie consumption caused by insufficient eating after breast cancer surgery.

(2) Breast cancer patients need to take enough protein. If there is no protein in the diet, it will lead to malnutrition edema, which is not conducive to postoperative wound healing and recovery of breast cancer patients. High-protein diet can alleviate the excessive consumption of protein caused by some diseases, reduce postoperative complications of breast cancer, and make breast cancer patients recover as soon as possible.

(3) A high vitamin diet is needed, and vitamin A can promote tissue regeneration and accelerate wound healing. Vitamin K is mainly involved in the coagulation process, which can reduce intraoperative and postoperative bleeding. When B vitamins are deficient, it will cause metabolic disorder, and wound healing and tolerance will be affected. Vitamin C can reduce capillary permeability, reduce bleeding and promote tissue regeneration and wound healing. Therefore, breast cancer patients must eat more fresh vegetables and fruits rich in vitamins before operation, and some patients may need to supplement vitamin tablets according to the doctor's advice.

Postoperative diet of breast cancer patients:

(1) Supplying protein foods such as milk, eggs, fish and bean products which are easy to digest and absorb can improve the anti-tumor ability of the body.

(2) Eat the right amount of sugar to supplement calories. The effect of supplementing glucose is better, so you should eat more sugar-rich foods such as honey, rice, noodles and potatoes to supplement calories.

(3) Eat more anti-tumor foods, such as soft-shelled turtle, mushroom, auricularia auricula, garlic, laver, mustard, royal jelly, etc.

(4) Vitamin A and vitamin C can prevent malignant transformation and diffusion of cells and increase the stability of epithelial cells. Vitamin c can also alleviate the general symptoms of radiation injury and improve the level of white blood cells; Vitamin e can promote cell division and delay cell aging; Vitamin B 1 can stimulate the appetite of patients and relieve the symptoms caused by radiotherapy. Therefore, we should eat more foods rich in the above vitamins, such as fresh fruits and vegetables, sesame oil, cereals, beans, animal offal and so on.

(5) Patients with radiotherapy and chemotherapy should generally eat cold food and cold drinks; For patients who feel cold, it is advisable to eat hot food.

(6) Diversified diet, paying attention to the color, fragrance, taste and shape of food, promoting patients' appetite, cooking food by steaming, boiling and stewing, avoiding indigestible food and prohibiting drinking.

(7) For those who have difficulty in chewing, swallowing, digesting and absorbing and lack of special nutrients after tumor operation in various parts, different diets and nutritional elements can be given according to the situation, and nutritional elements can be given when necessary to enhance the patient's resistance.
