Through genetic testing, you can tell you exactly whether there is a possibility or probability of a certain disease in a certain life time in the future, and give you an early warning notice so that effective preventive measures can be taken early.
The news of Yao Beina’s death is like a blockbuster, which not only shocked the entire entertainment industry, but also made everyone feel sad and sorry. From the outbreak of the award ceremony to the death, it will be one month. Recall that many stars have been killed by breast cancer: Anita Mui, Chen Xiaoxu, Ye Fan, Asan, and Audrey Hepburn. There are also some stars who struggle to fight cancer and eventually defeat the disease, such as Tsai Chin, Wang Mingxi, and the pre-planned Angelina Jolie.
Everyone knows that diseases are the most consuming, especially cancer. Then, we must take precautions against the disease. Oscar-winning Angelina Jolie has already reduced her risk of breast cancer by genetic testing and corresponding resection two years ago.
Relevant statistics show that breast cancer causes 458,000 deaths each year, and its incidence rate is increasing worldwide. Among them, the incidence rate in northern Europe and the United States is relatively high, and Asia is in a low incidence area. However, it is worth noting that the incidence of breast cancer in Asia has increased rapidly in recent years and has a tendency to become younger.
Under such high risks, it is a new hope to effectively prevent breast cancer by predicting the probability of breast cancer in advance and taking measures to take the initiative to avoid disease. This technology is the genetic test chosen by Julie to determine the probability of breast cancer by blood screening related genes.
What is genetic testing? It refers to the technique of detecting DNA by blood, other body fluids, or cells to determine the probability of illness. Genetic testing can diagnose diseases and can also be used to predict disease risk. Disease diagnosis is the use of genetic testing techniques to detect mutated genes that cause hereditary diseases. The most widely used genetic tests are the detection of neonatal genetic diseases, the diagnosis of genetic diseases and the auxiliary diagnosis of some common diseases. There are currently more than 1,000 genetic diseases that can be diagnosed by genetic testing techniques.
What has been very exciting in recent years is the development of predictive genetic testing. Use genetic testing techniques to detect the risk of disease before the disease occurs, prevent it early, or take effective interventions. More than 20 diseases have been predicted by genetic testing. Take Shanghai as an example, there are already more than 10 related institutions providing genetic testing. With the wind of genetic testing all the way to China, in the past two years, the genetic testing company represented by Huada Gene and Daan Gene has developed rapidly in China and has reached the international leading level in certain technologies.
What is the process of genetic testing? When testing, the gene of the subject is extracted from blood or other cells. Then, using the primers and PCR technology that can identify the genes that may have mutations, this part of the gene is replicated many times, and the mutation gene probe method, the enzyme digestion method, the gene sequence detection method, etc. with special markers are used to determine whether there is a mutation in the part of the gene. Or there are sensitive genotypes.
Our usual medical testing methods are to detect specific symptoms of the disease or existing lesions. The development of modern science has promoted the continuous development of medical testing methods, and can analyze the disease vertically or horizontally in depth.
The genetic history of disease families is caused by the inheritance of disease susceptibility genes, so genetic testing can detect these genetic susceptibility genotypes, and the detection accuracy reaches 99.9999%. Although at the beginning of the year the Health Planning Commission had released a batch of three professional genetic tests that could be used in hospitals, breast cancer susceptibility genetic testing is not listed. However, patients can still go to the relevant genetic testing center or physical examination center for testing.
Since the completion of the Human Genome Project in 2000, more and more gene functions have been successfully interpreted. More than 2,000 gene-related diseases have been discovered. More than 700 genetically related diseases have been developed and corresponding drugs and treatments have been developed. Containing cancer and many rare diseases, the development and application of its drugs are underway. At present, the technology of gene detection has gradually matured. In addition to the application of diagnosis and treatment, the detected genotypes can even predict the risk of disease not occurring according to the content of the database through digital statistical methods. More than 8 million people in the United States have been genetically tested. Therefore, genetic testing can accurately tell you whether there is a possibility or probability of a certain disease in a certain life time in the future, and give you an early warning notice so as to take effective preventive measures at an early stage.
However, some people have issued such a question: like the detection of breast cancer susceptibility genes, the domestic alone does about three or four thousand yuan, and there are not many patients who do a certain cancer genetic test alone. Many people will be able to The detection of the 30 or 40 kinds of genetic tests is done, the total cost is about 50,000 yuan, which is not a small amount for a common working family, and this is just the beginning. The author believes that it may take some time to spread this to the working class.
