Dr. Oz and I recently spoke about important new research that is showing that how you select, prepare and consume foods can be a powerful weapon for preventing cancer. The reason for this lies in our capillaries, the thousands of tiny blood vessels present in almost every square millimeter of our bodies.


The growth of new capillary blood vessels is called angiogenesis, a vital process for reproduction and healing. Cancer turns the body against itself by hijacking the angiogenesis process. Just as healthy tissues require oxygen and nutrients, malignant tumors need a blood supply to fuel their growth. But, unlike normal tissues, cancer keeps angiogenesis permanently switched on to ensure that it has a dedicated, uninterrupted blood supply.

Angiogenesis Makes Cancer Dangerous
A major reason cancer is so frustratingly difficult to cure is that by the time it can be detected, it is often very advanced, and like all advanced diseases, much more difficult to treat. In a person with advanced cancer, uncontrolled angiogenesis keeps cancer cells growing and allows them to spread. However, without angiogenesis, cancers can’t grow and become dangerous. This is why the microscopic cancers that form in our bodies all the time are mostly harmless. These cancers aren’t even visible on a standard X-ray or body scan. So, to effectively prevent cancer, angiogenesis needs to be brought under control before the tumor can get a foothold. This is where your everyday diet comes into play
