Explanation

Chemotherapy is a common treatment for cancer. Patients who receive chemotherapy take strong anti-cancer drugs meant to kill the cancer cells. Chemotherapy is given through an IV directly into a patient's veins or in pill form. While chemotherapy is a powerful tool for keeping cancer cells from reproducing, it can often make people feel quite sick because it kills other cells as well. The word literally means "treatment of diseases by chemicals," from the German Chemotherapie and its roots, the scientific prefix chemo-, "chemical," and the Greek therapeia, "healing."
