I. How do I look at “avoidance” and “hair”? 1.What is “taboo”? Taboo, generally refers to what not to eat or eat less, or refers to illness and medication during the need to pay attention to the diet, or the taboo on certain foods. It means to abstain from eating, abstain from eating, abstain from eating. Chinese and Western theories are different, and Chinese medicine attaches more importance to the taboo. When taking Chinese medicine to clear internal heat, you should not eat onions, garlic, pepper, mutton, dog meat and other hot food; in the treatment of “cold” when taking Chinese medicine, should be prohibited to eat cold food. In Chinese medicine, there are a lot of rules for taking medicine, and it is not advisable to eat certain food when taking medicine to avoid reducing the efficacy or aggravating the disease. For example, avoid radish when taking ginseng; avoid green onion when taking Changshan; avoid amaranth; avoid green onion, garlic and radish when taking Dihuang, He Shou Wu; avoid tea when taking Tu Fu Ling, make Jun Zi. When taking Chinese medicine, you should mainly drink plain water. When receiving Chinese medicine treatment, should also be in accordance with the doctor’s instructions and the requirements of taking medicine to avoid food, in order to prevent reducing the effectiveness or contrary to the Chinese medicine “comprehensive regulation of yin, yang, cool, heat and cure the root” principle. In short, according to the requirements of TCM, it is necessary to pay attention to “avoiding food” during taking medicine. Zhan Bihong, Department of Radiotherapy, Anhui Cancer Hospital Tumor patients, especially those with gastrointestinal tract diseases, should not eat any food that is cold, greasy, fishy, indigestible or with special irritation, such as ginger, onion, spicy, fried food, etc., during taking medicine because of the disease. It is important to note that although avoidance of food is beneficial to the treatment of disease, but can not be made absolute. Usually, avoidance of food is based on the disease and the nature of the medicine, do not make a generalization. For example, fish, shrimps, crabs, shellfish, tsubaki buds, mushrooms, and certain meat and eggs of poultry and animals, etc., those who have suffered from allergic diseases should pay attention to the choice to avoid food. Another example is hyperlipidemia, hypertension, coronary heart disease, stroke, etc. After the disease, the diet should be light, do not eat too much greasy and thick things. Many tumor patients pay too much attention to “taboo” which is not scientific. Due to the influence of tumor on body and the digestive function disorder caused by various treatments, most of the patients have malnutrition in different degrees, and “taboo” will make the patients not to drink this and not to eat that, which will only aggravate the nutritional deficiency of patients and reduce their resistance to disease. Especially for tumor chemotherapy and radiotherapy patients, the white blood cells in the body are often reduced, so it is not only inappropriate to “abstain from eating”, but also to emphasize comprehensive nutrition and supplement those microelements and animal and plant foods (except for those who are allergic to certain foods) that can prevent and fight cancer. According to the patient’s condition and the strength of digestive and absorption functions, a high protein, high energy and high vitamin diet should be provided to compensate for the excessive consumption of the body and improve the immune function of the body to fight cancer. Domestic and foreign clinicians have not found any food that can promote the spread and metastasis of cancer cells. Except for not smoking, not drinking strong alcohol, not eating moldy, smoked and burnt food, and cold, cold, greasy, spicy and other irritating or carcinogenic foods that are harmful to some patients, there is no need to blindly “taboo”. No matter from modern medicine, or Chinese medicine theory, tumor patients should have some “taboos” according to their condition and treatment needs. 3.What is “hairy food”? The so-called “hairy food” refers to the food that is particularly likely to induce certain diseases (especially old diseases) or aggravate existing diseases. In fact, “hairy food” is only a folk expression, and has not been recognized by modern science. Therefore, its exact definition cannot be found in authoritative medical textbooks and journals. The term “hairy substances” may refer to certain foods that can aggravate or trigger the onset of disease. Mainly include: fish, carp, eel, ark, clam, crab, shrimp and sea cucumber, etc., livestock meat such as mutton, dog, donkey, horse and hen meat, and vegetables such as leek, celery, parsley and fennel. Now it seems that some of the “hair” is related to allergic diseases, such as asthma, urticaria, etc.. This is caused by the allergic reaction of individuals to certain high protein foods. From the perspective of modern pathology, tumors are neither allergic diseases nor sores and swellings in the traditional sense, and are not related to the concept of “hair products”. It is also impossible for “hair products” to cause the metastasis and recurrence of tumor. From the perspective of modern nutrition, “hairy food”, which is rejected by many patients, is rich in protein and vitamins and is precisely an excellent food; “hairy food” can not only ensure the nutrients needed by the body, but also increase its immunity and disease resistance. In clinical practice, we have not seen any cases of tumor metastasis and recurrence caused by eating certain foods, nor have we seen such reports in official journals and academic papers at home and abroad. On the contrary, there are many patients who cannot tolerate radiotherapy and chemotherapy due to malnutrition caused by not paying attention to dietary regimen, thus forcing the treatment to be interrupted. From the point of view of modern nutrition, hair products, which are rejected by many patients, are rich in protein and vitamins, which not only ensure the nutrients required by the body, but also increase its immunity and resistance to disease. Possible mechanisms of the role of hair products: hair products can lead to the recurrence or aggravation of old diseases, some scholars have summarized that there are three possibilities: (1) is the above-mentioned animal food contains certain hormones, which will promote certain functions in the body hyperfunction or metabolic disorders. For example, glucocorticosteroids can induce the spread of infection, bleeding ulcers, seizures, etc. when the physiological dose is exceeded, causing a relapse of the old disease. (2) The allergenic proteins contained in certain foods can cause the recurrence of allergic diseases. For example, sea fish, shrimp and crab often cause skin allergy sufferers urticaria, eczema, neurodermatitis, impetigo, psoriasis and other intractable skin disease attacks. Tofu milk sometimes also causes recurrence of asthma. (3) are some of the more irritating foods, such as alcohol, onions and garlic and other spicy irritant food to inflammatory infections lesions, easy to cause the spread of inflammation, boils go yellow. In summary, the hair refers to food, but specifically refers to some easy to induce certain diseases (especially the old disease persistent disease) or aggravate the disease has been issued food. In Chinese medicine, it is mostly food with the properties of pungent, warm, dry and Yang, meat and fishy, greasy and stagnant. Can cancer patients eat chicken? There is a legend among some cancer patients that cancer patients cannot eat chicken! Even eggs cannot be eaten! In our daily medical work, many tumor patients and their families often ask us whether they can eat chicken and eggs after having cancer. They think that old hen and other nutritious food are the so-called “hairy food”, which will cause tumor development or recurrence if patients eat them. Our answer: This kind of caution, as mentioned above, is not based on science and is a misnomer and misrepresentation. Cancer has not been found to be necessarily related to “hair products” so far. On the contrary, tumor is a chronic wasting disease. Due to the abnormal and rapid proliferation of cancer cells and the destruction of human tissues by cancer tumors, patients consume more nutrients. Therefore, their needs for various nutrients are higher than those of normal people. It has been proved that insufficient nutrition for human and animals, long-term intake of low protein, low vitamin and diet lacking various trace elements will decrease the immune function of the body. Increasing the chance of tumors in certain tissues or potentially aggravating the cancer condition. Some cancer patients actually die from malnutrition rather than from cancer. Animals lacking vitamin A are susceptible to tumors induced by chemical carcinogens, while vitamins C and E have the effect of inhibiting the formation of certain tumors. Cancer patients, due to the damage of cancer cells to the organism, can lead to the disorder of physiological function; due to the effect of tumor toxin, it can cause the change of organism metabolism; as the tumor of digestive system is more likely to cause the physiological dysfunction of digestive organs, plus various anti-cancer treatment measures can also cause nutritional disorders, such as surgical treatment can sometimes cause malabsorption, vitamin deficiency and electrolyte disorder; head and neck radiotherapy can cause appetite Radiotherapy to the head and neck can cause decrease in appetite and loss of taste; abdominal radiotherapy can damage the normal function of gastrointestinal tract and cause diarrhea; chemotherapy drugs can cause nausea, vomiting and abnormal taste, etc. This shows that improving nutrition should be one of the important measures for comprehensive cancer treatment and recovery. If we blindly regard many essential nutrients as “hairy” and dare not eat them, it is bound to aggravate the malnutrition of patients and greatly reduce the resistance of the body, which is not only prone to various complications, but also hinders various anti-cancer treatments and directly affects the efficacy and recovery. Besides, any animal high-protein food is digested and decomposed into amino acids, fat and carbohydrates through the gastrointestinal tract and is absorbed. If tumor patients have a psychological effect of worrying about eating chicken, they should not eat it, but this is not the same thing as chicken will lead to tumor growth and recurrence. Third, can cancer patients eat eggs? Some cancer patients and patients recovering from treatment are not only afraid to eat chicken, but also eggs. They think that eggs are also “hairy”. This misconception is obviously unfounded, as it is suspected to promote the growth of cancer cells. Eggs mainly contain ovalbumin and ovalbumin, a complete protein, 99.7% of which can be absorbed by the body. An egg weighs about 50 grams and contains 7 grams of protein and 6 grams of fat, producing 82 kcal of caloric energy. The ratio of amino acids in egg protein is very suitable for human physiological needs, easy for the body to absorb, and the utilization rate is up to 98% or more. Eggs are high in calcium, phosphorus, iron and vitamin A. They are also rich in B vitamins and contain many other essential vitamins and trace elements, making them a good tonic. The fat it contains is emulsified in the yolk and is easily digested and absorbed; the lecithin and lecithin it contains are of great benefit to the human nervous system and growth and development; the protein it contains is of high quality. Nowadays, one of the nutritional compound amino acid infusion solutions commonly used in medicine is composed of 14 kinds of amino acids, which are formulated according to the structural ratio of amino acid components in eggs. This kind of compound amino acid is called whole egg model, which is widely used in patients with gastrointestinal diseases and digestive tract absorption disorders; for improving malnutrition state and patients with hypoproteinemia caused by various reasons, it provides raw materials for the body to synthesize proteins, so it can be seen that eggs have high nutritional value for patients. Studies have shown that eggs not only do not cause tumor recurrence, but egg yolk oil can significantly enhance physical fitness, delay aging, prevent geriatric diseases and cancer prevention. Human aging, malignant tumors and some geriatric diseases (such as atherosclerosis) are importantly related to free radical-induced lipid peroxidation in the body. It is now believed that free radicals damage DNA (deoxyribonucleic acid), the genetic material in cells, causing the body to age and possibly cause cellular malignancy and cancer, while egg yolk oil is rich in phospholipids (mainly lecithin) and vitamins A, E and carotene and other fat-soluble antioxidant vitamins, which have a significant antioxidant effect on the human body and play a direct or indirect role in scavenging free radicals, protecting unsaturated lipids in cell membranes and preventing them from oxidative damage. Therefore, egg yolk oil has the effect of slowing down the aging process, and the proteins contained in eggs are far better than plant proteins such as soybeans. Therefore, eggs are the most complete, the most reasonable composition of nutrients, the highest nutritional value, the best digestion and absorption of food, and are one of the most common animal protein foods consumed by humans. From a nutritional point of view, steamed egg custard, fried eggs and egg soup are the most desirable ways to eat. Fourth, can cancer patients drink tea during recovery? The main active ingredients in tea are tea polyphenols, amino acids, tea polysaccharides, caffeine, minerals and trace elements, vitamins and so on. Among them, the most important is polyphenolic compounds. Tea polyphenols is the general name of tea tree phenolic substances and their derivatives. Research has proved that tea polyphenolic compounds have obvious antioxidant, free radical scavenging, sterilization, anti-virus, enhance immune function, lowering blood lipids, lowering blood sugar, anti-cancer and many other effects. Chinese tea has been blessed with a natural gift. It is not only a thirst quenching and refreshing, eliminate fatigue, active thinking people’s favorite beverage, especially green tea also has health functions and anti-mutation, antioxidant, anti-cancer and anti-cancer efficacy, has been confirmed by domestic and foreign research. Tea contains tea polyphenols and other cancer inhibiting substances, in vitro experiments have shown that tea polyphenols have a significant anti-human lung and cervical cancer cells, and can block the chemical synthesis of strong carcinogens in the human body nitrosamines and improve the role of immune function. Some studies have shown that tea can reduce radiation damage and has an anti-radiation effect. Drinking tea can counteract the harmful effects of smoking. Tea can also be diuretic, which helps to eliminate edema. Therefore, appropriate consumption of tea is beneficial and harmless. However, because tea contains more tannic acid, its astringent effect hinders the absorption of vitamins and nutrients, should not drink more strong tea after meals. For patients with poor sleep, because tea contains caffeine, especially in the evening should not drink more tea. When taking Chinese medicine, it is also not advisable to drink tea, otherwise it will affect the absorption of Chinese medicine. V. Why should cancer patients have regular review and follow up? Rehabilitation treatment is the continuation of clinical treatment, and regular review and follow-up is also the continuation of clinical treatment. After finishing the initial treatment, cancer patients should go to the hospital for regular review according to the medical prescription and keep in touch with each other for a long time. This special contact between oncologists and patients is called “follow-up visit”. This kind of follow-up is very valuable to strengthen the experience of cancer prevention and treatment. Why do cancer patients need regular review and follow-up? Even though some tumors are recently cured due to early detection and early treatment, a few patients may have recurrence or metastasis with the passage of time, and such small lesions of early recurrence or metastasis do not cause any discomfort and symptoms to patients. In addition, most of the patients are intermediate and advanced stage patients, and the initial treatment of many tumor patients is not complete enough, some of them need periodic maintenance and consolidation treatment, and some of them inevitably have recurrence or metastasis later. If early detection is made through follow-up, timely and appropriate treatment measures can still be taken to control the disease again. If late detection is made, the treatment effect is often not good, and regular review or follow-up can lead to early diagnosis and treatment, and prevent late detection of recurrence or metastasis and delay in treatment. Patients may have complications, sequelae and toxic side effects after cancer treatment, and due to the lack of knowledge in this area, they may mistakenly think that the disease has recurred or metastasized and worry a lot. Through review and follow-up doctors to make it clear to patients and appropriate rehabilitation treatment, patients’ worries and symptoms can be relieved and survival quality can be improved. In general, cancer patients are reviewed once a month ~ once every two months in the first year after treatment, once every two to three months in the second year, and once every six months thereafter, and whenever there are special circumstances, so as to prevent problems before they occur. In addition, the follow-up work can provide important information and basis for summarizing the development pattern of tumor and treatment experience, and promote the development of oncology, so tumor patients should insist on regular follow-up.
