Some researchers are very skeptical of the benefits of shark cartilage in curing or preventing cancer. Some people believe that sharks don't get cancer and thus certain properties of the shark cartilage must prevent the cancer. This belief started when unsubstantiated research results claimed that compounds in shark cartilage could prevent the growth of new blood vessels which is essential for tumour growth and survival - angiogenesis. Researchers claim that these results are not accurate and also that cancers are rare in sharks and do occur. They believe a more in depth study needs to be done in order to justify the killing of so many sharks and the false belief of a possible cure delivered to many people.
