Stops angiogenesis : Avastin (bevacizumab), and was the first commercially available angiogenesis inhibitor. Its main action is the inhibition of the function of a natural protein called vascular endothelial growth factor (vegf) that stimulates new blood vessel formation. Because most malignant tumors are highly dependant on angiogenesis to obtain a blood supply and nutrients Avastin can stop or delay growth.
