Circulating Tumor DNA Screening finds the true murder of cancer
Although scientists continue to work hard, humans still have little knowledge of cancer. Many cancers are unclear and can only be inferred from the life habit of patients. For example, if you have a smoking habit, we infer that it is the cause of lung cancer. For example, people who love to drink, we infer that it is the cause of liver cancer. Until the discovery of genes, people's awareness of cancer has greatly deepened. In the early stage of cancer formation, the body cell genes will be mutated. Usually, these mutant cells will take 10-15 years to become tumors, which is called "precancerous lesions" in medicine. The cause of cell mutation may be inherited, or it may be due to acquired factors. These variant cells have the potential to induce a variety of cancers, and more than 500 genes are known to have variant cells. Circulating Tumor DNA Screening is the use of molecular medical detection technology to detect whether there are genes in the blood with variant cells, to find out where the body has problems.
In addition, the greatest benefit of Circulating Tumor DNA Screening is to detect the presence of mutant cells before the tumor has formed, and to prompt the subject to avoid further deterioration of the mutant cells and eventually become cancer. It is possible that each cancer is caused by a variety of tumor genes, so it is very important for the genetic testing company to select which tumor genes to test. Due to detection costs and clinical research data, most genetic testing companies will select some of the most common tumor genes to detect, usually about 50-60. These tumor genes may induce about 20 to 30 common cancers. Special attention should be paid when choosing the test products. Do not choose to cover multiple cancer types and ignore the number of circulating tumor genes. For example, A Gene company detects 50 circulating tumor genes covering 30 inducible cancers, and B Gene company detects 59 but only covers 24 inducible cancers. It seems that A Gene company covers more cancers, so it is better than A Gene company, but in fact, because A Gene company only detects 50 circulating tumor genes, the specificity of the detection is relatively low, meaning that most circulating tumor genes will affect. In all 30 cancers, when the test results are positive, it is difficult to judge that the organ in the body is problematic. The most ideal test is to detect all relevant tumor genes, but there are only a few tumors covered. If the relevant tumor genes are found in the blood, you can clearly know where the problem is.
Finally, Circulating Tumor DNA Screening is a very effective test for cancer screening. It is recommended for people with high cancer risk to do the test once a year. For example, family history, obesity, chronically ill patients, disorder diet or work schedules, long-term work in harsh environments long-term mental stress, etc.
