Does eating shark cartilage prevent cancer in humans?

Shark cartilage: Eating shark cartilage does not prevent cancer in humans. The quack literature is replete with claims of how this works including statements that suggest that sharks never get bone cancer -- of course not, they have no bones. The one claim that is true is that eating shark cartilage will definitely result in the death of more sharks.

No: There are no clinical trials that show that shark cartilage prevents or treats cancer.

Very controversial: Claims of use of shark fins to lower cholesterol & to combat cancer & heart disease have not been scientifically supported at this time. There is a health risk in ingesting shark fins. It is a predator fish with of high levels of bmaa (neurotoxin), arsenic & methylmercury.
