What Is Angiogenesis and Why Is It Important in Cancer?
Angiogenesis is the process of forming new blood vessels. Tumors need a blood supply to grow beyond a certain size and to spread (metastasize) to other parts of the body. Cancer cells can secrete growth factors like VEGF (vascular endothelial growth factor) to stimulate angiogenesis, enabling them to receive nutrients and oxygen and remove waste products.
