This concept is so intriguing because it suggests a new and possibly much simpler way of warding off disease. Instead of different treatments for, say, heart disease, Alzheimer's and colon cancer, there might be a single, inflammation-reducing remedy that would prevent all three...
...course the granddaddy of all anti-inflammatories is aspirin, and millions of Americans already take it to prevent heart attacks. But evidence is growing that it may also fight colon cancer and even Alzheimer's by reducing inflammation in the digestive tract and the brain...
...inflammatory cycle is obvious - as with chronic heartburn, which continually bathes the lining of the esophagus with stomach acid, predisposing a person to esophageal cancer. Other times, it's less clear. Scientists are exploring the role of an enzyme called cyclo-oxygenase 2 (COX-2) in the development of colon cancer. COX-2 is yet another protein produced by the body during inflammation...
...should you be taking Celebrex to prevent colon cancer? It's still too early to say. Clearly COX-2 is one of the factors in colon cancer. "But I don't think it's the exclusive answer," says Ray DuBois, director of cancer prevention at the Vanderbilt-Ingram Cancer Center in Nashville, Tenn. "There are a lot of other components that need to be explored...
That may soon change. Researchers are looking beyond aspirin and other multipurpose medications to experimental drugs that block inflammation more precisely. Any day now, Genentech is expecting a decision from the FDA on its colon-cancer drug, Avastin, which targets one of the growth factors released by the body as inflammation gives way to healing. Millennium Pharmaceuticals is testing a different kind of drug, called Velcade, which has already been approved for treating multiple myeloma, against lung cancer and other malignancies. But there is a sense that much more basic research into the nature of inflammation needs to be done...
