The reduction in colorectal cancer rates in the US since 1986 is probably due to better detection rates, says a study in the latest issue of Diseases of the Colon and Rectum (1999; 42). An annual drop of 1% over the past thirteen years is the result of early screening and the removal of precancerous polyps rather than lifestyle changes, the study believes. Colorectal cancer is believed to be linked to total fat consumption. Although Americans are eating less saturated fat, total fat consumption has not decreased, the study says.
