What are the benefits of Avastin?
Blocking VEGF may prevent the growth of new blood vessels, including normal blood vessels and blood vessels that feed tumors. Unlike chemotherapy that attacks the cancer cells, the purpose of Avastin is to block the blood supply that feeds the tumor. This can stop the tumor from growing.
