angiogenesis inhibitor
(an-gee-o-GEN-eh-sis)
A substance that stops new blood vessels from forming. It tries to fight cancer by stopping the growth of blood vessels that feed a tumor. As a result, the tumor starves and shrinks.
The targeted therapy Avastin (chemical name: bevacizumab) is an angiogensis inhibitor.
