Cancer is caused by DNA changes that control the way cells grow and divide. These changes can be inherited, but most of them occur randomly in a person's life, which may be caused by cell division or exposure to carcinogens of destructive DNA.

Matters needing attention in tumor gene detection:
The accuracy of any biological detection method can't reach 100%, but the genetic detection methods recommended by international and domestic publicity at present are verified by a large number of experimental data and clinical evaluation, which can well display the genetic status of tumors.
So although the sensitivity and specificity of different gene detection methods are slightly different. But generally speaking, as long as it is a testing technology that has passed the national official certification, it can be used. The accuracy is still very high.
Before receiving genetic testing, please collect as much family history information as possible, and then clearly tell the doctor or genetic counselor about the personal and family genetic history. This will help to better understand the risk of illness. You can discuss any questions or concerns about genetic testing with your doctor or genetic consultant. According to the results of genetic testing, discuss the next disease treatment plan or health management measures.
