Thank you for this. Anti-angiogenic agents are one of the forefronts in current research from all sides. See this article by Ginsky & Raz about blocking the angiogenic pathway with Modified Citrus Pectin (with credit to Roy & Alyson Dittman, Gten members who found the article for me):

In the article the authors also discuss the potential for increasing the effectiveness of chemo drugs that work on disrupting this pathway, which is exactly what the newest (and therefore most expensive...$10,000/dose) chemo drug that I'm taking is designed to do.
