First: play less and sleep more at night Many people may not think that going to bed earlier at night is a rare physical therapy for cancer prevention. This is because cancer cells themselves are abnormal cells produced in cell division, an abnormal condition in the process of cell division. In turn, cell division in the human body happens to take place during sleep. Therefore, reasonable and sufficient sleep can allow cell division activities to be carried out in an orderly and normal manner, thus preventing the production of cancer cells. Second: Open the windows at least twice a day for 15 minutes each time Even in winter, even if the weather is cold, we should find ways to open the windows for 15 minutes twice a day. This is because, even if a house has been renovated for a long time, the carcinogens in the decoration materials are difficult to be completely removed. What’s more, many building materials may release carcinogenic radon and radon daughters. If windows are not opened, such substances will gather and cause cancer. Third: Quit smoking decisively after 40 years old. Many people will find that the incidence of various chronic diseases starts to increase after the age of 40. Cancer is no exception. Therefore, we have to quit all habits that may trigger cancer after the age of 40. Smoking is the first and foremost. This is because many of the chemical components and radioactive elements in tobacco are carcinogenic. The radioactive elements combine with the hair dots in tobacco and are deposited in the lungs, forming radioactive dots that eventually become the source of lung cancer. They seem like time bombs buried deep in the lungs that will detonate at some time and induce cancer. Smokers, second-hand smokers, and third-hand smokers cannot escape from this law. Fourth: Control your weight. Losing weight is “losing cancer”. Do not think that weight loss is just to lose fat, so that we look more beautiful. In fact, in a sense, losing weight is also “cutting out cancer”. It has been clinically proven that the development of many cancers is related to obesity. Among them, breast cancer is a kind of cancer that has a relatively close relationship with obesity. Therefore, we should not treat weight loss as a slogan. It is closely related to the safety of our lives. Fifth: make rules for yourself and eat the right amount of vegetables and roughage every day. One of the most prominent nutritional problems of modern people is an overly fine diet, resulting in a long-term absence of coarse fiber in the gastrointestinal tract to help digestion and cleaning. This can provide a soil for the accumulation of carcinogens. The development of colorectal cancer is closely related to this. Therefore, we should eat some coarse grains or coarse fiber vegetables quantitatively every day, just like taking medicine, to ensure the usual bowel movement and normal detoxification system. Sixth: Have a medical checkup once a year. In fact, there is no better way to prevent cancer than to have a physical examination once a year. It is very necessary for screening cancer and can be called the last hurdle of cancer prevention. To give up any opportunity of medical check-up is irresponsible to life and living. Seventh: less socializing, eat your own food. Socializing is something that cannot be avoided in modern society. Since it can not be avoided, then try to reduce the number of times. Chinese dinner habits is one of the best soil for cross-infection of H. pylori. And H. pylori is exactly the initiating factor of gastritis. Gastritis, erosive gastritis, atrophic gastritis and, in the end, often gastric cancer develop. Therefore, H. pylori is also known as the initiating factor of gastric cancer. So, it is best to eat your own meals, by yourself. Eighth: Eat a little less barbecued and fried meat food. Eating grilled and fried meat foods is a very dangerous cancer-causing behavior. This is because, such food itself contains carcinogens. Moreover, most of these carcinogens are fat-soluble. Therefore, carcinogens are more likely to flourish in the context of a large intake of meat.
