Gene-targeted therapy is a common treatment method in the treatment of malignant tumors. The price of gene targeting therapy is not clearly defined, but varies from hospital to hospital, generally between 2000-5000, and may be higher depending on the drugs used. It is also recommended to pay attention to the gene testing before doing gene targeting therapy, to find the gene of the lesion for targeted therapy, and to use effective methods to control the synthesis of dna to achieve the purpose of treating the disease.
