Once these new vessels reach the tumor, they allow the supply of blood that provides oxygen and other nutrients to the tumor. This facilitates the tumor grow.
Avastin is believed to work by closing up one of the central signals that causes angiogenesis. In distinction from others, Avastin blocks a protein named vascular endothelial growth factor. This may give up Avastin to affect the tumor in various ways:
