Shark cartilage and cancer
Name: Denise Scherer
How is shark cartilage used to treat/prevent cancer, and how
widely accepted is this method?
Although there has been speculation in the past that there
may be some factor in shark's cartilage that prevents cancer,
recent research by the National Cancer Institute could not
confirm this, and there is no scientific evidence that I know of
to support that theory.
In fact, though it doesn't happen too often, sharks do indeed
contract cancer, and do develop tumors.
For more information, refer to the article "Sharks do get Cancer"
by Tim Beardsley in SCIENTIFIC AMERICAN, Oct. 1993.
