Slide 3  :  What Is Tumor Angiogenesis? <  >  

Tumor angiogenesis is the proliferation of a network of blood vessels that penetrates into cancerous growths, supplying nutrients and oxygen and removing waste products.

This signaling activates certain genes in the host tissue that, in turn, make proteins to encourage growth of new blood vessels.
