What if you could prevent the polyps from forming in the first place? In 1991 Michael Thun, an epidemiologist with the American Cancer Society, made an intriguing observation: people who regularly take aspirin are less likely to develop colorectal cancer. It turns out that aspirin blocks the production of an enzyme, called COX-2, that is found in 90% of all tumors and half of the polyps in the large intestine. Apparently most of these abnormal tissues need COX-2 to grow. Stop the production of the enzyme, and you might be able to prevent the cancer from getting larger...

"What was surprising was the magnitude of the increase," says epidemiologist Dr. Walter Willett of the Harvard School of Public Health. "It's rare to see such a strong effect...

First he tells the School Sisters of Notre Dame, a group of Roman Catholic nuns who have given their bodies--and, after death, their brains--to help Snowdon study the slow mental wasting known as Alzheimer's disease...
