Avastin – Bevacizumab uses, dose and side effects
Avastin contains the active substance bevacizumab, which is a humanized monoclonal antibody (a type of protein normally produced by the immune system to help protect the body against infections and cancer). Bevacizumab selectively binds to a protein called VEGF ( human vascular endothelial growth factor), which is found inside the body’s blood and lymph vessels. VEGF protein causes blood vessels to grow in tumors and these blood vessels supply the tumor with nutrients and oxygen. When bevacizumab is bound to VEGF, tumor growth is prevented by blocking the growth of the blood vessels that supplytumor one with nutrients and oxygen.
