Genes are innate, as long as they are born, they will only have the meaning of eugenics. No drug can change genes. It is only a profitable way to prevent cancer by detecting cancer genes.
The key point is that ordinary people don't know what gene technology is at present, but only know that it is high technology. Real genetic testing costs thousands of dollars at a time. At present, many so-called gene companies do not do genetic testing, but infer which genes may have problems through some physiological indicators, which is low in cost. If genetic knowledge is popularized, it will be another situation. Just like the concept of frying nano before, it once penetrated into all aspects of food, clothing, housing and transportation, and now there is no news.
Genetic testing is a technique to detect DNA through blood, other body fluids or cells. It is to take the oral mucosa cells or other tissue cells shed by the examinee, amplify their genetic information, and then detect the DNA molecular information in the examinee's cells by special equipment, so as to predict the risk of diseases in vivo, analyze the various genes contained in them, and make people know their own genetic information, so as to avoid or delay the occurrence of diseases by improving their living environment and habits.
