Angiogenesis inhibitors . Inhibiting the formation of blood vessels adjacent to tumors.

Just like healthy body tissue, tumors need a steady blood supply. If they don't get one they die.  By creating their own "network" of blood vessels, tumors develop an independent and reliable source of nutrients and oxygen, which "feed" the tumor. Without new blood vessels, tumors cannot grow beyond the size of a pea. Angiogenesis is a word that means new growth of blood supply.

In fact tumors are crafty and secrete hormone-like substances called growth factors, especially one known as vascular endothelial growth factor, or VEGF. This attaches to nearby cells, which triggers new blood vessels to sprout toward the tumor. These blood vessels provide the tumor with a steady blood supply and nutrients. Without VEGF, new blood vessels are unable to grow and support the tumor.

Anti-angiogenic (angiogenesis: growth of new blood vessel) substances are thought to work by stopping the growth of new blood vessels. This process "starves" the tumors of the blood and nutrients necessary for growth. These types of treatments are called angiogenesis inhibitors. Of course the majority are just complicated and expensive drugs.

But did you know that shark cartilage has exactly the same action—at a fraction of the cost? No, of course you were not told. It’s bad news for sharks! In fact liquid bovine (beef) cartilage appears to give similar results. That’s easier on the environment and actually tastes better.

It’s possible that Noni juice does this too. At least one study we found published in a reputable medical journal thought so.

Other remedies that inhibit the formation of new blood vessels are zinc, vitamin B2, green tea and turmeric.
