Can Tumors Stop Angiogenesis?

Because tumors cannot grow beyond a certain size or spread without a blood supply, scientists have developed drugs called angiogenesis inhibitors, which block tumor angiogenesis.

What can affect tumor angiogenesis?

Angiogenesis is stimulated when tumor tissues require nutrients and oxygen. Angiogenesis is regulated by both activator and inhibitor molecules. However, up-regulation of the activity of angiogenic factors is itself not sufficient for angiogenesis of the neoplasm.

Can tumor growth stop without angiogenesis?

Without an adequate blood supply tumors will not grow. Tumors produce factors that stimulate the formation of blood vessels to provide them with the food and oxygen they need. The process of blood vessel formation is termed angiogenesis.
