For the cancer therapy are used anticancer drugs. When anticancer drugs are taken by the body intravenously or by mouth, the treatment is called systemic drug therapy, and when the drugs are used only in the place where the tumor is, the treatment is called topical (local) drug therapy. Chemotherapy and target therapy The chemotherapy is a type of system and /or a local anti-tumor therapy, which uses cytotoxic agents (substances that repress the mechanisms of cell-division and the process of multiplication of the tumor cells). The target therapy is a kind of systemic anti-tumor therapy, which uses the so-called biological materials, also called target drugs. They are organic molecules that selectively activate or repress the essential for tumor cells biological processes and thereby lead to their death and suspension of tumor growth. The effect is implemented by capturing a specific location (receptor) of a certain cellular molecules and because of this focus, the drugs are called target drugs.
