Colorectal Cancer and Colonics
Colorectal cancer is the No. 2 cancer killer in the United States. Colorectal (colon) cancer is often curable when detected early. There is no scientific evidence that any colon cleansing regimen significantly decreases one's risk of developing colorectal cancer.
The death rate from cancer in the US has declined steadily over the past 25 years, according to annual statistics reporting from the American Cancer Society.

Be suspicious before you purchase a colon cleanser. Someone’s wallet is likely to benefit from the transaction more than your colon. Eat right, drink plenty of fluids (water), consume fiber, and speak with your doctor about colorectal cancer screening.
