FDA warns against so-called 'cancer cures'

WASHINGTON, June 17 (UPI) -- The U.S. Food and Drug Administration says it has sent warning letters to 23 U.S. companies selling products that claim to cure or prevent cancer.

The FDA also warned both U.S. and Canadian consumers against using or purchasing the products, which include tablets, teas, tonics, black salves and creams sold under various names on the Internet.

"Although promotions of bogus cancer 'cures' have always been a problem, the Internet has provided a mechanism for them to flourish," said Margaret Glavin, the FDA's associate commissioner for regulatory affairs. "These warning letters are an important step to ensure that consumers do not become the victim of false 'cures' that may cause greater harm to their health."

The FDA said consumers should consult their healthcare provider about discontinuing use of the products and seek medical attention if they have experienced any adverse effects.

The products contain such ingredients as bloodroot, shark cartilage, coral calcium, cesium, Cat's Claw and mushroom varieties such as Agaricus Blazeii, Shitake, Maitake and Reishi.

The FDA said examples of fraudulent claims include: "Causes cancer cells to commit suicide" and "80 percent more effective than the world's number one cancer drug."
