Shark cartilage: For several decades, shark cartilage has been proposed as a cancer treatment. Studies have shown shark cartilage or the shark cartilage product AE-941 (Neovastat ®) to block the growth of new blood vessels, a process called "anti-angiogenesis," which is believed to play a role in controlling growth of some tumors. There have also been several reports of successful treatments of end-stage cancer patients with shark cartilage, but these have not been well-designed or included reliable comparisons to accepted treatments.

Many studies have been supported by shark cartilage product manufacturers, which may influence the results. In the United States, shark cartilage products cannot claim to cure cancer, and the U.S. Food and Drug Administration (FDA) has sent warning letters to companies that promote their products in this way. Without further evidence from well-designed human trials, it remains unclear if shark cartilage is of any benefit in cancer, and patients are advised to check with their doctor and pharmacist before taking shark cartilage. Caution is advised when taking shark cartilage supplements, as numerous adverse effects including an increased risk of drug interactions are possible. Shark cartilage should not be used if the patient is pregnant or breastfeeding unless otherwise directed by a doctor.
