Targeted drug therapy mainly targets malignant tumors. The mechanism of action of targeted drugs is to inhibit a point in time, or a pathway point, in the tumor growth pathway. For example, the anti-angiogenic drugs VEGF or its receptor inhibitors, bevacizumab and apatinib mesylate are all such drugs. Targeted drugs are very effective in treating tumors, but it should be noted that the drugs are expensive and must be financially available. Although targeted drugs are good, they cannot completely solve cancer cells, and there is also a certain degree of drug resistance, which may not be suitable for every patient’s physical condition. If drug resistance occurs after a period of use, there is no way to continue using it, which also means that by this time, the cancer cells have already experienced full deterioration.
