What is bevacizumab (Avastin) used for?
Avastin (bevacizumab) is used to treat several cancers, including colorectal cancer and non-small cell lung cancer, and it is also used in some other oncology settings. Its role is to block vascular endothelial growth factor (VEGF), which helps tumors form blood vessels needed for growth.
Is there a generic or biosimilar bevacizumab instead of Avastin?
There can be biosimilar versions of bevacizumab (they are not “generic drugs” in the same way as small-molecule medications). Whether a biosimilar is available and covered can depend on country, regulator approvals, and payer formulary rules.

- dosing schedules and formulation differences
- prior treatment response
- any history of infusion reactions or side effects
