In this age of cancer, we all do something to “prevent cancer” to a greater or lesser extent. There are reports that radiation may cause cancer, immediately put on anti-radiation clothing and then use the computer; TV said that overnight food contains carcinogens, all the leftovers at home do not stay; listen to what others say to eat food can kill cancer cells, will unconsciously often buy to eat …… In fact, in our lives, cancer-causing factors can be said to be ubiquitous, and to take measures to prevent cancer! There is nothing wrong, but in the process of cancer prevention, we should not ignore the protection of our own immunity, so that we are free from cancer attacks, cancer prevention should start from the “care” of our immune system. We all have cancer cells in our body. Normal immune function can effectively remove cancerous cells in our body. Do we all have mutated cancer cells in our body every day? This may make many readers feel “shocked”, normal people will produce some abnormal mutated cells every day. Anyone who has had a cancer checkup will notice that almost all tumor markers are not “zero” but have a normal range for this reason. Cancer cells are produced every day, but it doesn’t mean that you will get cancer. This is because our body’s normal immune system is able to remove these cancerous cells in a timely and effective manner. A very interesting experiment has been done, which injected a kind of cancer cells into the body of a normal adult, and it would not develop into cancer, which indicates that there exists a natural anti-tumor immunity in the body of a healthy adult; however, injecting this kind of cancer cells into the body of a cancer patient, these cancer cells would be able to develop into malignant tumors, which indicates that the cancer patient has lost the ability of this kind of natural anti-tumor immunity, which suggests that the organism’s immune function is closely related to the occurrence of cancer. The immune system is the defense organ in the human body, and the immunoreactive cells produced by the immune system form the “national defense force”, defending the human body from external or internal “enemies”. External “enemies” mainly include viruses, bacteria, fungi and other harmful pathogens; internal “enemies” mainly refer to some mutated abnormal cells. The process of the “defense force”: first, a small number of “reconnaissance troops” to find the invasion of the “enemy”, and then the “enemy Then the information of the “enemy” is transmitted to the “barracks” of the “National Defense Forces”, which generates a large number of “combat troops” and rushes to destroy the “enemy”. The “barracks” generate a large number of “combat troops” that rush over to destroy the “enemy”. Rarely catching a cold does not mean not having cancer Poor immune function will leak cancer cells “How can I get cancer, I am usually in good health, not catching a cold all year round, and I have not been hospitalized for more than ten years?!” Many patients can’t accept it when they learn they have cancer, they think they are in good health and therefore can’t possibly get cancer. Many people think that people who often catch colds and have poor health should be more prone to cancer, but in fact, this is not necessarily true. Some studies have shown that when people catch a cold (mostly bacterial or viral infections), it is an opportunity to stimulate the function of the immune system. And after a viral infection, once the immune system realizes that the virus has invaded, it will mobilize to destroy these invading viruses, and then the “cold symptoms” that make us feel all kinds of discomfort will appear. If you get a cold (infected by a virus) and don’t have much of a reaction to it, it may not actually be a good thing, it may just mean that you, the immune system, is not as responsive to the invading virus. When the immune system is not as good, it is unable to recognize the cancerous cells (cancer cells are derived from normal cells in the body and resemble normal cells; and cancer cells produce camouflage such as glycoproteins or mucopolysaccharides to wrap themselves up or make it more difficult for the immune system to recognize the cancerous cells by changing the immune monitoring points), allowing the cancerous cells to be the ones that slip through the cracks; and even if they are recognized, the immune system can’t destroy the cancerous cells fast enough to keep up with the invading virus. Even if they are recognized, the immune system’s ability to destroy the cancerous cells does not keep up with the increase in the number of cancerous cells, and may give the missed cancerous cells a chance to develop into cancer. Of course, in some cases, the immune system functions normally, but the cancer cells are too “cunning” to escape the surveillance of the immune system, and after a period of time, they will also develop into cancer. Taking care of immune function from daily life Suppressed emotions and lack of sleep are immune killers Many readers will be concerned about what I can do to prevent my immune function from declining. People in adulthood with the increase in age immunity inevitably declined, especially after the age of 50 years of age, the body’s immune function decline trend is more obvious, which is also after the age of 50 years of age, the risk of cancer significantly higher for one of the important reasons. In daily life, people over 50 years old often have old people and young people under them, and at the same time, they shoulder heavy pressure of life and work, and tend to have overdraft of physical strength and energy, which can easily cause the decline of immune function, therefore, people after 50 years old need to take better care of themselves, and avoid accelerated decline of immune function due to over exertion. The factor of age is something that none of us can avoid. But apart from that, we can still make a difference in many ways. Healthy lifestyle and good mental quality are crucial to enhance the immune function of the body. For example, frequent staying up late, long-term sleep deprivation, mental suppression, and poor rest may cause a decline in the immune function, which provides an opportunity for cancerous cells to escape from the surveillance of the immune system, and may easily lead to the occurrence of cancer. Therefore, we have to develop good living habits, pay attention to dietary hygiene, participate in some suitable physical exercise, maintain a good state of mind, and enhance our immunity to the best state, which plays an important role in the prevention and treatment of tumors. 1.Sweat for 30 minutes every day this is the most affordable way to prevent cancer. You don’t need to develop 6-pack abs, you don’t have to run a marathon, as long as you exercise for 30 minutes a day, 5 days a week. Walking, dancing, cycling, climbing stairs, all kinds of sports can be. 2, drink tea or coffee tea helps prevent cancer has long been confirmed. Because green tea contains catechins and vitamins A, C and other antioxidants with anti-cancer effects, these anti-cancer ingredients green tea content, followed by oolong tea, black tea. Coffee can also reduce the incidence of certain cancers. The latest studies in the United States, Canada and Japan have found that coffee can help reduce the probability of developing liver cancer, renal cell carcinoma, breast cancer and colorectal cancer in women. 3, eat more fresh fruits and vegetables suggested that children before the age of 6, should consume 5 portions of fresh fruits and vegetables every day; more than 6 years of age schoolchildren, teenage girls and female adults, every day to eat 7 portions of fruits and vegetables; and adolescents and male adults, should be 9 portions of fruits and vegetables every day. One serving of vegetables is about 100 grams of raw weight, and one serving of fruits is about 150 grams. Daily intake of vegetables should be more than 1 portion of fruit. 4, less salt, do not drink sugary drinks daily intake of salt is not more than 6 grams, less sugary drinks, drink plain water is ideal, natural fruit juice is not more than 150 ml per day, and do not eat moldy cereals and beans. 5.Keep relaxed mood to reduce pressure, depressed mood can easily induce cancer, and many cancer patients review the two or three years before the onset of the disease, often in a state of high stress physically and mentally. Medical research has found that mental stress and long-term negative emotions will cut down the immune function, depression makes the body’s ability to repair DNA decline, the probability of developing cancer significantly increased.
