Chemotherapy is the use of drugs to destroy cancer cells. It works by keeping the cancer cells from
growing and dividing to make more cells. Because cancer cells usually grow and divide faster than healthy

Chemotherapy with these powerful drugs is called standard chemotherapy, traditional chemotherapy, or
cytotoxic chemotherapy.
Several other types of drugs also treat cancer. Many of the newer drugs are called targeted drugs or
