The Second Leading Cancer Killer in America is Preventable!

Over 56,000 men and woman will die this year from colon and rectal cancer. Please don't let it be you, your family members, or your friends.

Help us spread the word that a simple screening, called a colonoscopy, can and will save lives.

Colorectal cancer affects both men & women, usually ages 50 and older. Even if you have no symptoms and no family history of colon polyps or colon cancer, you need to get screened beginning at age 50.

While it is very important to be aware of the symptoms, colorectal cancer is often referred to as the silent killer. In many cases symptoms aren't present until the disease has progressed.  Please don't wait.

Our team of physicians, nurses, and support staff are dedicated to provide specialized care in the prevention and treatment of digestive diseases. Count on us for the care and support you need.

Loving hands over stomach.

Schedule your screening today by calling Digestive Disease Consultants at (309) 454-5900.
