Shark Cartilage and Bovine Cartilage
Both shark cartilage and bovine cartilage are dietary supplements.

A process called angiogenesis is the development of tiny blood vessels that supplies a tumor with nutrients to grow. I. William Lane, PH.D., author of "Sharks Don't Get Cancer" believes that shark cartilage is anti-angiogenic. John F. Prudden, M.D. is a proponent of bovine cartilage and claims its anti-cancer ingredient is a complex surgar molecule that stimulates the immune system to fight cancer.

My opinion. I heard on the radio the other day that sharks DO get cancer. "In fact," the radio man said, "sharks get cartilage cancer." I will have to do a little research to validate this statement. End of my opinion

There are other anti-angiogenesis drugs under investigation today.
