Butt Seriously.

When it comes to colorectal cancer, early detection could save your butt—and maybe even your life.

Screening and Prevention

Many people don’t realize that colorectal cancer is highly preventable. The American College of Gastroenterology recommends colonoscopy screenings beginning at age 50 for both men and women. African Americans should begin screening at 45. Unlike other cancer screenings which can only detect a problem, a colonoscopy could prevent colorectal cancer by removing precancerous polyps during the exam. Removal of polyps prevents up to 90 percent of colorectal cancer and, with appropriate follow-up, the chance of death from colorectal cancer is further reduced.


Colorectal cancer is the second-leading cause of cancer deaths in the U.S. Early colorectal cancer usually has no symptoms. Warning signs typically occur with more advanced disease and may include rectal bleeding, blood in the stool, a change in bowel habits and cramping pain in the abdomen. You could be at higher risk if you:

  • Are over age 50
  • Are African American or of Eastern European Jewish descent
  • Have a personal history of colorectal polyps, previously treated colorectal cancer or inflammatory bowel disease
  • Have a personal history of radiation to the abdomen (belly) or pelvic area to treat a prior cancer
  • Have Type 2 diabetes, are obese or are physically inactive
  • Eat a diet that’s high in red or processed meat and/or diets low in calcium, fruits, vegetables and whole-grain fiber
  • Are a smoker or drink alcohol frequently



Every 10 years or as recommended

Colonoscopies have long been considered the gold standard for colorectal cancer screening and detection. Because it lets doctors see the entire colon, it’s the best way to detect and remove polyps—helping prevent colorectal cancer.

Both our hospital GI Center and Endoscopy Center in Arlington Heights use state-of-the-art diagnostic technology and high-definition imaging. Because of this, our detection rate for polyps is 57 percent, well above the national benchmark of 25 percent.

Our facilities are designed for efficiency and patient privacy. The average time patients spend registering, undergoing and recovering from a colonoscopy at our facilities is 2 ½ hours.


Treatments vary based on the size, location and if the cancer has spread. The three primary treatment options include surgery, chemotherapy and radiation therapy. Our comprehensive colorectal cancer program gives you the care you need close to home. Our team includes board-certified gastroenterologists, a board-certified colorectal surgeon and a dedicated colorectal cancer patient navigator. NCH offers advanced treatment for colorectal cancer including:

Utilizing da Vinci’s technically advanced robotic arms and 3D imaging, NCH surgeons can perform highly complex surgeries through incisions as small as one or two centimeters.
The surgeon removes parts of the colon affected by cancer.
A series of drugs taken intravenously or in a pill form that can kill cancer cells.
The surgeon removes all or part of the rectum.
A special type of chemotherapy that takes advantage of differences between normal cells and cancer cells.
Activates or suppresses the immune system to elicit or amplify a response that can help fight cancer.
Halcyon™, a new radiation therapy delivery system, enables us to provide highly targeted treatment with improved quality, speed, accuracy and comfort for patients.
