Colon Cancer Screening Q & A

What is Colon Cancer?

Colon cancer, or colorectal cancer, is a type of cancer that affects your colon, large intestine, or rectum. These are essential components of your digestive system that are responsible for breaking down food for energy and eliminating the byproducts of digestion from your body.

Colon cancer usually starts off as a noncancerous growth called a polyp that slowly develops into full-blown cancer. 

This is why colon cancer screenings are essential. They can catch polyps and other abnormal growths early, so your specialist at Illinois Gastroenterology Group can remove them before they become life-threatening.

What are the Symptoms of Colon Polyps?

If you have polyps in your colon, you may notice symptoms like:

  • Blood in your stool
  • Abdominal pain
  • Constipation or diarrhea
  • Nausea
  • Vomiting
  • Mucus discharge


Polyps in your colon usually don’t have any symptoms, and most patients only find out they have them with a screening.

What Happens During a Colon Cancer Screening?

Illinois Gastroenterology Group uses a colonoscopy procedure to screen for colon polyps and diagnose colon cancer.

During a colonoscopy, your specialist inserts a tiny, flexible tube with a fiberoptic camera and light into your rectum. The camera and light provide a well-lit, magnified image from the inside of your colon in real-time and allows your specialist to check for any abnormal growths.

If you have polyps or other growths that concern your doctor, they take a biopsy to determine whether the growth is benign or cancerous. They can also completely remove the polyp during the colonoscopy.

How Long Does a Colonoscopy Take and What is the Recovery Time?

At Illinois Gastroenterology Group, a team member can conduct your colonoscopy procedure in 20-30 minutes. You need to rest for 30 minutes after the procedure until your sedative wears off, after which you can return home and resume your regularly scheduled activities.

How Often Do I Need a Colon Cancer Screening?

The American Cancer Society recommends regular colon cancer screenings for patients over the age of 45. You may need more frequent screenings or need to start them earlier if you have:

  • A family history of colon cancer
  • Personal history of colon cancer or polyps
  • Personal history of bowel diseases


Colonoscopies can be uncomfortable, but this is an important screening test as early detection can increase your chances of surviving colon cancer by 90%.
