Newswise - The rising popularity of shark cartilage extract as an anti-cancer treatment is a triumph of marketing and pseudoscience over reason, with a tragic fallout for both sharks and humans, according to a Johns Hopkins biologist writing in the Dec. 1 issue of Cancer Research.

"Since shark cartilage has been promoted as a cancer cure, not only has there has been a measurable decline in shark populations, but cancer patients also have been diverted from proven, effective treatments," said Gary K. Ostrander, a research professor in the departments of Biology and Comparative Medicine at The Johns Hopkins University.

In the paper, titled "Shark Cartilage, Cancer and the Growing Threat of Pseudoscience," Ostrander writes, "Crude shark cartilage is marketed as a cancer cure on the premise that sharks don't get cancer. That's not true, and the fact that people believe it is an illustration of just how harmful the public's irrationality can be."

In fact, Ostrander's paper details more than 40 examples of tumors in sharks and related species, dating back to the mid-1800s.

In the paper, Ostrander and a team of researchers from the Registry of Tumors in Lower Animals not only dissect what they call the "fallacious arguments" that have successfully convinced desperate cancer patients to purchase and ingest crude shark cartilage extract, but they also sound a "wake-up call" for society to become more scientifically literate and, thus, less vulnerable to skillfully mass-marketed illogical claims.

"People read on the Internet or hear on television that taking crude shark cartilage extract can cure them of cancer, and they believe it without demanding to see the science behind the claims," Ostrander said. "This shows how the electronic media has increased the potential harm of pseudoscience, turning what would otherwise be quaint cultural curiosities into potential serious societal and ecological problems. The only way to combat this is to ensure that government leaders and media professionals receive adequate scientific training based on reason, and that they also develop critical thinking skills."
