Article first time published onWhat happens when Avastin stops working?
Now some researchers are wondering if after Avastin is stopped, cancer cells spread more aggressively than before, dulling the drug’s effect. Such a “rebound effect” could explain why Avastin therapy is not resulting in bigger survival gains even as the drug makes pictures on imaging scans look better.

The mechanism of blood vessel formation by angiogenesis is initiated by the spontaneous dividing of tumor cells due to a mutation. Angiogenic stimulators are then released by the tumor cells. These then travel to already established, nearby blood vessels and activates their endothelial cell receptors.
