For drugs to control the growth of cancer cells, they can usually be divided into chemotherapy drugs, immunotherapy drugs and targeted therapy drugs, as follows: 1. Chemical drugs: they are also commonly known as chemotherapy drugs, such as paclitaxel, docetaxel, fluorouracil and platinum, adriamycin, etc. These belong to intravenous chemotherapy drugs.
