The summer festival belongs to the mid-volcano stage, which is the hottest stage of the year. Now let’s talk about the things that tumor patients should pay attention to in summer. In hot summer, people like to blow air conditioner, eat cold drinks, drink cold beer and eat sweets, not knowing that these are important triggers of tumor and also important factors of tumor aggravation. It is not difficult to find that the number of patients with pleural fluid increases in summer, especially in the south, which has much to do with air conditioning in summer. This is not yet recognized by modern medicine, but it has been discussed in the famous medical text “Nei Jing” during the Warring States period in China. The “Spiritual Pivot – Water Distension” says: “What about the intestinal tumor? Qibo said: the cold gas outside the intestines, and the Wei Qi fight, the gas can not be honored, because there is a system, fetish and internal, the evil gas is up, the polyps are born. Its first birth is as large as a chicken egg, slightly to benefit from the large, to its formation, such as the shape of the pregnant child, a long time away from the years, pressed by the firm, pushing it to move, the monthly events to time down, this is also its symptoms.” This passage means that intestinal and gynecological tumors are mostly caused by cold evil. Zhang Zhongjing, the sage of medicine in the Eastern Han Dynasty, also placed special emphasis on cold evil causing disease, and wrote “Treatise on Typhoid Miscellaneous Diseases”, the title is very clear, external sensations and miscellaneous diseases are mostly caused by cold evil. Allergic rhinitis patients nowadays are mostly related to drinking cold, and the “Inner Classic” cloud “form cold drinking cold injury to the lungs”, that is to say, wearing less clothes, form cold (external cold) and excessive drinking cold food (internal cold) and other easy to hurt the lungs. The lungs are open to the nose, and the formation of rhinitis is closely related to external cold and cold drinking. Therefore, in the summer, the use of air conditioning should be restrained, not when it can be opened, and when it is really hot in the three volt days, the temperature should be adjusted higher, or dehumidification instead of refrigeration, and tumor patients should wear more clothes in the air conditioning room, do not blow the cool air directly. As far as tumors are concerned, lung adenocarcinoma, osteosarcoma, abdominal tumors, etc. are closely related to cold, or excessive drinking of cold, or people who love beauty wear less and bare more, or their feet suffer from cold for a long time. In my clinical summary, I found that HER-2 strong positive patients are mostly ladies who like cold drinks or cold food, or love to wear skirts in winter; patients with osteosarcoma growing in the lower limbs mostly have no history of trauma, but have a history of excessive cold drinking, or with a preference for sweet food. What are the cold items? It includes items taken out of the refrigerator and some cold vegetables and fruits. Some people are afraid, can’t even eat fruits? The main point is that fruits cannot replace normal meals, but can only be used as a supplement to meals and eaten in small amounts as much as possible. You often hear me say not to eat too much fruit, why is this? Fruit is too sweet, and cooked fruit is even sweeter, so you can’t eat too much of it. As for raw fruit and vegetable juices, they are extremely sweet and cold, which is a big no-no for tumor patients. Sweet food is delicious, but it is also the cause of dampness. Those who eat too much sweet food tend to have sticky stools, and their stools tend to hang on the wall of the toilet. In general, dampness is invisible, diffuse and sticky, so tumors with heavy dampness are not easy to cut, such as glioblastoma of the brain, glioblastoma and pancreatic cancer, etc. Another characteristic of dampness is that dampness is injected downward, so abdominopelvic tumors, lower limb tumors and ascites are heavier with dampness. Therefore, tumor patients, especially those with the above mentioned tumor types, should pay more attention to stay away from cold and wet sweet diet in summer, so as not to give the conditions for tumor to come back. In addition, many places in China have been hit by heavy rainfall and flooding, but tumor patients must pay attention not to soak in water for a long time, one because of cold and the other because of wet water, which are not good for tumor patients and are important factors for the development of tumor disease. Therefore, it is recommended that tumor patients, especially those in the south, can do more moxibustion (e.g. Zhonggui, Guan Yuan and other points) in summer to improve immunity and remove dampness from their bodies. It is worth mentioning that tumor patients are forbidden to use any equipment (such as moxibustion box) when moxibustion, only hand-held moxibustion can be used, moxibustion box temperature does not reach, penetration is not strong, the point is not allowed, but easy to let the development of the disease.
