Mechanism of action

Bevacizumab binds to circulating VEGF, a key signaling protein that promotes angiogenesis (new blood vessel growth). By neutralizing VEGF, the drug inhibits the formation of new blood vessels that tumors require to grow and metastasize. This anti-angiogenic mechanism reduces tumor perfusion and can slow or halt cancer progression.
