March 8, 2001 -- This year, an estimated 56,700 Americans will die from colon cancer, a preventable disease. Though early detection is key to prevention and successful treatment, the proportion of the U.S. population screened for the disease remains amazingly low, according to a government report released Thursday.

The number of Americans over age 50 that were screened from 1997-1999 edged up a mere 3% from about 41% to 44%, the report shows.

These numbers are especially disappointing considering that at least one-third of these cancers would be prevented if people over age 50 were screened regularly.

Public health officials say that healthcare professionals and the public have failed to embrace national guidelines issued in the mid-1990s recommending that people aged 50 and older have regular colon cancer screenings.

"Efforts to address barriers and to promote the use of colorectal cancer screening should be intensified," write the authors of the report published in Thursday's Morbidity and Mortality Weekly Report, a publication of the Centers for Disease Control and Prevention.

The second leading cause of cancer-related death in the U.S., colon cancer occurs in an estimated two out of every 1,000 people. That means 135,400 new cases will be diagnosed in 2001, according to CDC estimates.

Screening is key because early detection saves lives. The screening tests can detect the disease in people with no symptoms who may have an early form of the disease. If caught early, cancer specialists say it greatly improves the chances of a successful treatment.

For example, if the cancer is confined to the wall of the intestine, explains Anil Rustgi, MD, chief of gastroenterology at the University of Pennsylvania in Philadelphia, the survival rate is much better. Rustgi says that the 5-year survival rate for patients whose cancer is confined to the intestine is about 90%, compared with about 10% for those patients whose disease has spread, or metastasized, to other organs.

"If you do find cancer [with screening], it's great to get it at the early stages" before it has metastasized, Rustgi tells WebMD.
