Tumor angiogenesis refers to the process by which new blood vessels form from pre-existing ones to supply a growing tumor with necessary nutrients and oxygen. This process is typically stimulated by the release of angiogenic factors by the tumor cells. One of the most well-known factors is vascular endothelial growth factor (VEGF). Inhibiting angiogenesis is a strategy used in some cancer treatments to starve the tumor of its blood supply.
