The difference between traditional treatment and genetic testing
Cancer is a disease caused by genetic mutations
Traditional cancer treatments include surgery, radiation therapy and chemical therapy. The former two are localized therapies. When cancer cells metastasize, chemical therapy must be used for overall treatment. However, chemical therapy often has severe side effects that are difficult for patients to deal with and some even give up treatment.
Since the first target drug Imatinib became available in 2000, cancer therapy became significantly related to individual genotypes. Target drugs must be administered according to the patient’s cancer cell genetic traits. The American FDA recommends that before targeted drugs are administered, corresponding biomarker tests should be conducted to ensure the effectiveness and safety of the treatment. Thus, a personalized drug requirement demand has been created. This is also the advent of the personalized medical care age.
