Shark cartilage has no benefit in lung cancer, study says
May 26th, 2010
Shark cartilage was once widely promoted as an anti-cancer agent and is still via the Internet for that purpose, based on the mistaken belief that sharks do not get cancer. The possibility that the cartilage could be beneficial was supported by early studies which suggested that it has anti-angiogenic properties — that is, it prevents the growth of blood vessels that nourish tumors. But the first clinical trial of a shark cartilage product shows that it has no value at all.
