Chemical Name: BEVACIZUMAB (be-vuh-SIZ-uh-mab)
Common uses
Avastin is a monoclonal antibody used in combination with other cancer medicines to treat colon or rectal cancer that has spread to other parts of the body. Avastin reduces the growth of new blood vessels. By reducing the growth of new blood vessels, the supply of oxygen and nutrients cancer cells need to survive is reduced. This may help to slow growth of cancer cells. Avastin is not a cure for colorectal cancer. Your physician may determine that Avastin could be used to treat other conditions.
