In Greek, â€œangioâ€ means vessels and â€œgenesisâ€ is birth. Blocking angiogenesis enables us to undercut cancerâ€™s spread. Angiogenesis is the process our bodies use to grow new bloods vessels. Cancers can hijack this process to recruit their own private blood supply to feed themselves. Without these lifelines, cancers remain tiny and canâ€™t become dangerous. Many foods and beverages contain natural cancer-starving molecules that prevent tumors from acquiring blood vessels.
