Dear Walt,
Thank you for writing to me about shark cartilage. I am very familiar with it's properties. Researchers have shown it promoted anti-angiogenesis (the word you were looking for), which is helpful to control the spread of cancer cells. A large human study of shark cartilage did not show shark cartilage to help with tumor reduction, but it was a valuable pain suppressant. Therapeutic dosage for shark cartilage is 1 gm per kg of body weight (example: 150 pound person would need about 90 capsules a day! More effective and realistic anti-angiogenesis compounds include EPA (omega 3 fatty acids) and soy. If you would like more information about the efficacy of dietary supplements specific to various cancer sites, you may be interested in my book, Challenge Cancer and Win!, which details food and supplement plans for 16 kinds of cancer.
Best,
