In recent years, cancer patients tend to be younger and younger, and in the fight against cancer treatment methods are also advancing, people have been studying how to prevent cancer before it occurs, so the market appeared a variety of genetic testing to screen for cancer
Heard of the genetic testing many people will think that it is a particularly high-end program, and the fact is also true, the price is indeed very high, fewer than The price is very high, tens of millions of dollars, or tens of thousands of dollars. Is genetic testing as amazing as it sounds? Here's more about the details from DuoMu Health (a one-stop overseas high-end medical consulting service provider).
What is genetic testing all about?
Genetic testing is a technique that detects DNA through blood or cells. It begins by extracting peripheral blood or tissue cells from the subject, amplifying the genetic information inside, and then using specialized equipment to detect the DNA molecules inside to analyze the types of genes and genetic defects, and to determine whether their expression is complete or not
We can find out what a person's genetic makeup is in a genetic test. We can know the individual's genetic information in the test, so as to predict in advance the chances of future diseases
Genetic testing is also able to detect mutated genes that may cause hereditary diseases, the most widely used in the detection of neonatal hereditary diseases, diagnosis, in addition to hereditary diseases, can also be used to assist in the diagnosis of common diseases
Cancer has a close connection with mutation, mutated genes will also be used to diagnose cancer. Mutated genes also affect the growth and division of cancer cells, and these mutations may also be hereditary. Genetic testing is a test that compares the genetic profiles of tumors to identify mutated genes
However, checking for cancer through genetic testing is not applicable to everyone. If there is a history of cancer in the family, genetic testing is still necessary
Specifically, who should undergo a genetic test to detect cancer
1, a member of the family who was diagnosed with cancer at a very young age
2, a close relative who has a rare cancer that is closely related to heredity
3, a member of the family who has a known genetic mutation
4, a member of the family who is found to have a mutation
4, the discovery of symptoms and diseases associated with hereditary cancers, such as familial adenomatous polyposis, gastrointestinal polyps, etc.
Genetic testing should be used mainly to guide cancer treatment, but also for screening for cancer risk. Genetic testing can also help people to understand their personal risk of developing the disease, but this can only be used as a means of assessment and prevention.
