Avastin® (bevacizumab) is a tumor-starving (anti-angiogenic) therapy. Avastin is designed to block a protein called vascular endothelial growth factor, or VEGF. Normal cells make VEGF, but some cancer cells make too much VEGF. Blocking VEGF may prevent the growth of new blood vessels, including normal blood vessels and blood vessels that feed tumors.
Interferon alfa boosts the immune system so it can better attack cancer cells. The purpose of Avastin is to prevent the growth of new blood vessels. This includes normal blood vessels and blood vessels that feed tumors.
New blood vessels feed the tumor so it can grow and spread.
Avastin helps prevent blood vessels from reaching the tumor; this could starve the tumor.
