In recent years, the incidence of breast cancer is rapidly increasing in China, especially in some big cities with fast economic development. In Shanghai, breast cancer became the first malignant tumor among women in the early 1970s. The Breast Surgery Department of Wuxi Chinese Medicine Hospital, Du Yaru, emphasizes that “if the righteousness exists within, the evil cannot dry up.” To help the righteousness means to enhance the immune function of human body and inhibit the growth of cancer cells. How to improve the resistance of the body after breast cancer surgery? The following points should be noted: 1. Supply protein foods that can be easily digested and absorbed to help wound healing and enhance immunity. Common high-protein foods include milk, eggs, fish, poultry, shrimp, soy products, etc., but less red meat, such as beef, pork and mutton, should be eaten. 2. Eat more foods with anti-cancer effects, such as garlic, mushrooms such as mushrooms, shiitake mushrooms, monkey head mushrooms, etc. Soft and firm foods, such as taro, water chestnuts, water chestnuts, jellyfish, kelp, nori, etc. 3, vitamins A and C have the role of preventing cellular malignancy and proliferation, increasing the stability of epithelial cells. Vitamin C can also prevent the general symptoms of radiation damage and can increase the level of white blood cells; vitamin B1 can promote the appetite of patients and reduce the symptoms caused by radiation therapy. Therefore, supplementation with rich vitamins and fiber, whether during surgery or radiotherapy is quite useful, such as a variety of fresh vegetables and seasonal fruits: cabbage, tomatoes, carrots, spinach, fungus, citrus, watermelon, kiwi, apples, grapes, strawberries, etc. 4.Depending on your condition, you should take raw ginseng, white ginseng or American ginseng during the treatment period, and after the treatment, you can still take ginseng supplements in winter. 5.Most of the breast cancer is related to estrogen in the body, breast cancer patients should avoid applying tonic medicine, such as royal jelly, royal essence, hashish film and other health products containing estrogen and growth hormone, and eat less chocolate, cream, ice cream. Coffee, anti-seasonal fruits or fruits with abnormal shape and color should be avoided. Some tumor patients rely too much on supplements and engage in normal diet hastily, which is a wrong practice that puts the cart before the horse and runs counter to the traditional principles of health care. Tonic is not something that can be used casually. At the same time, the diet should be moderate, should not be excessive. Excessive nutrition and obesity have a negative impact on the treatment of breast cancer. In the long-term life of breast cancer patients after treatment, they should adhere to the principle of eating in moderation but not in excess, while ensuring nutritional needs. The total daily intake of calories, fats and sugars should be well understood in the dietary arrangement, and overeating and binge drinking should be avoided.
