Angiogenesis inhibitors are a thing that we use to "pull the plug" on certain types of cancers. If you look up the hallmarks of cancer, there are about 10 attributes which a cancer possesses that makes it able to grow, with one being angiogenesis, others being evasion of the immune system, resistance to apoptosis etc. Each of these attributes have been targeted in the pursuit to fight cancer. Axitinib is an example of a angiogenesis inhibitor.
