Colorectal Cancer Awareness

Colon and Rectal Cancers Screening

Colorectal (colon and rectal) cancer is preventable and highly treatable when caught at an early stage. People who are diagnosed at early stages have over a 90 percent chance of a cure and survival.

The risk of colorectal cancer increases with age and family medical history of the disease. Lynch Syndrome is the most common hereditary syndrome associated with high risk.

Colorectal cancer screening helps find precancerous polyps early so they can be removed before they turn into cancer. Talk to your primary care provider about the right screening for you.

Who should be screened

If you are 45 to 75 years old, you should get screened for colorectal cancer according to the CDC (Centers for Disease Control & Prevention). Adults 76 to 85 years old should discuss screening with their doctor.


There are different types of screenings for polyps and cancer using the latest screening tests. These include:

  • Colonoscopy - uses a thin, flexible tube with a camera. Colonoscopy remains the gold standard for finding and removing pre-cancerous polyps.
  • Double-contrast barium enema - uses a radiocontrast agent called barium and X-rays
  • CT colonography (CTC), or virtual colonoscopy, using CT scanning (provided at specific sites)
  • Flexible sigmoidoscopy - uses a shorter tube with a camera to examine only the lower colon and rectum
  • Stool (feces) tests - checks for blood

Talk to your provider about which screening is right for you.

What to expect at a screening colonoscopy

When it comes to getting a colonoscopy, you’re not the only one who has questions. But for every person who asks a question, there are dozens who won’t. That’s why we’ve gathered the six most commonly asked colonoscopy questions and answers:

  • Emptying your entire digestive system before a colonoscopy is an essential step. It lets your doctor get a clear look at your colon and remove polyps that either are, or may become, cancerous. But is the preparation itself bad? In truth, many consider it the most unpleasant part of the process, but don’t worry! For most, the amount of liquid you’re required to drink in one session has been reduced from the amounts of the past. Chilling the mixture helps and the texture is also a bit easier to drink. Your doctor will do whatever they can to help make the process as easy as possible. And a few hours of bathroom time are nothing compared to the lifetime health advantages.

  • Colonoscopies are considered the best procedure to check for polyps and other abnormalities that can lead to cancer in the colon and rectum. While you’re under a sedative, your physician gently expands your colon with air, then uses a long, flexible scope with a camera to view the rectum and colon, it is also ingeniously equipped to painlessly remove any polyps along the way.

  • The procedure itself is actually quite short, taking anywhere from 20 minutes to an hour. That being said, you’ll want to clear your schedule for the day and have a driver to take you to and from your appointment, as the effects of the sedative can take several hours to wear off.

  • Everyone perceives pain differently, but thanks to the light sedative, the vast majority of people experience no pain during the procedure. The most you can expect is some minor abdominal discomfort (like common gas pains) during the recovery period.

  • Because a light sedative is used during the procedure, most people feel close to their normal selves when they wake up. You can also expect minor abdominal discomfort until you pass the air your doctor uses to expand your colon during the procedure (don’t worry, this is normal).

  • For most people, it’s recommended that you receive your first colonoscopy at age 45 and then repeat the process once every 10 years. However, it’s important to understand your personal risk factors like family history, weight, race and other factors and to talk to your provider about whether or not earlier screenings are right for you.
