Is it necessary for normal people to do genetic testing?

Genetic testing is of great significance to two types of people. First, young men and women whose parents have obvious genetic diseases consult before marriage to decide whether they can have children. Second, when cancer patients choose targeted drugs, they need to detect whether the targeted drugs are effectively matched with oncogenes. General healthy people don't need to do genetic testing. Everyone's genome will have many mutations or defects, many of which are polygenic disease-causing defects. In other words, all kinds of single defects will not cause diseases or just increase the possibility of diseases. Even if this mutation defect is found out, there is no need to have an ideological burden. If you are worried for a long time that you will get sick, just paying attention to health care like normal people will not do much to prevent diseases, but may cause mental instability and cause various diseases.

The process of genetic testing is divided into three stages:

(1) health stage: that is, the body is in a healthy or sub-healthy state. At this time, the genetic examination is mainly to predict the risk of disease, so as to have targeted prevention and defense. The price of this kind in the market generally ranges from 500-3000 yuan, among which there are three common ones, such as hypertension, hyperlipidemia, hyperglycemia, breast cancer, cervical cancer, colorectal cancer and monogenic genetic diseases with clear genetic relationship.

(2) Early stage: in sub-health state. There are no obvious symptoms at this time, but it is already the early stage of the disease. We can use glycolipids, hormones and enzymes to detect breast cancer, such as cancer antigen 125, ovarian cancer antigen 15-3, prostate cancer T-PSA and so on. These contents are available in general medical institutions, each ranging from tens to hundreds.

(3) Clinical stage: at this time, it is already tumor and cancer, which is equivalent to genetic examination for clinical treatment. Its main function is to diagnose whether the disease is hereditary or not, or to carry out targeted radiotherapy and chemotherapy according to the type and classification of cancer and the individual genetic status of patients. At this time, it is not up to you to decide whether to do it or not. Generally recommended by the doctor's diagnosis and treatment plan, of course, the price is relatively expensive, usually ranging from several Qian Qian to tens of thousands.

Concluding remarks

But if we intervene early and find out early, at least the cure rate of early cervical cancer and lung cancer is 100%! The cure rate of breast cancer and rectal cancer is 90%! The cure rate of gastric cancer is 85%! The cure rate of liver cancer is 70%! Therefore, genetic examination is an aid, combined with physical examination and other health equipment.
