With the completion of the human genome project, people have stepped into the biological era from the industrial age. The development of industry is not enough to meet the physiological needs of human beings, and people begin to seek their own mysteries. People's birth, aging, disease, death, appearance, skin color and other differences are all determined by gene control, and genes are the source of our human mysteries. The completion of the human genome project has also enabled people to understand the human body and diseases at the molecular level for the first time. Genes, as fragments of cellular DNA molecules, determine various life phenomena and are the basic factors for the inheritance of racial traits. People's birth and death, people's height, skin color and even people's intellectual emotions are inseparable from genes. It is precisely because everyone's genes are different and different.
Why do some people smoke all their lives, lung cancer never comes to you, and some people never smoke, but they die of lung cancer? Why do some patients with severe hepatitis eventually turn into liver cancer, while others don't? It's all about genes. These genes lurk in the human body, and once the external environment is suitable, it will cause diseases. These genes are susceptible to diseases. Modern medicine believes that almost all diseases except Shanghai are the result of the combined action of congenital genetic risk factors and acquired environmental risk factors. Disease-susceptible genes are like seeds of diseases, which will germinate and cause diseases when they meet suitable environmental conditions. The premise of preventing seed germination is to find the seeds of diseases in time, and genetic testing is to help us find the seeds of diseases lurking in the body. Gene detection technology is one of the most reliable methods to find hidden dangers of diseases. By screening the susceptibility genes of human diseases, the risk of diseases can be judged, so that the occurrence of diseases can be delayed or completely eliminated through targeted prevention and regulation of the environment of disease seed germination. In fact, there is a long process from susceptible genes to disease occurrence. If we can make good use of genetic testing, we may find problems and solve them before the disease forms. The biggest difference between genetic testing and physical examination is that our purpose is not to find diseases earlier, but to take measures before diseases occur and prevent them before they happen.
Just like Angelina Jolie, a famous Hollywood movie star, she is also a public beneficiary based on testing. Because her mother, grandmother and menstruation all died of breast cancer, there is a genetic history of this disease in her family, so she gave herself a genetic test to understand her risk. The results show that the probability of breast cancer is as high as 87%, and the probability of ovarian cancer is as high as 50%. Therefore, she resolutely removed her breasts and ovaries in March of 20 15, which reduced her risk of illness to less than 5%. It can be said that she will not suffer from it again in this life. After she benefited from it, she published an article entitled "My Medical Choice" in The New York Times, which brought genetic testing into public view for the first time, so people called it "Julie Effect".
As we all know, many diseases are difficult to cure, such as coronary heart disease, diabetes, stroke and so on. Therefore, we don't want to wait for the disease to form before doing remedial work. The most valuable effort is to prevent the occurrence of these diseases. According to a survey data, the average misdiagnosis rate of colon cancer in China is 4 1.5%, and the average misdiagnosis rate of middle-aged and young people is 72.8%. Because colon cancer usually has no obvious symptoms in the early stage, it is easy to be ignored. Colonoscopy is one of the most effective methods to diagnose colon cancer. Because colonoscopy is painful, the hospital will not arrange for the medical examiner to do colonoscopy without any symptoms. But when people have symptoms, it is often too late to do colon cancer examination. And if we find the susceptibility gene of colon cancer, we will recommend colonoscopy even if there are no symptoms. Only in this way can colon cancer be eliminated in the bud.
Nowadays, more and more people benefit from "genes", so it is very important to know their health status. Only know how much wine you can drink, how much meat you can eat, what kind of exercise you are suitable for, and even what medicine you should use and how much you should use after you get sick. . . . . . If we can know these things now, why wait until the problems appear to solve them? It is predicted that medicine will surpass clinical medicine in the future to treat diseases will gradually become a reality. When you have a private health record, life will shine like never before.
