The Importance of a Colonoscopy: A Lifesaving Screening for Colorectal Cancer Awareness Month

March is Colorectal Cancer Awareness Month, a time dedicated to raising awareness about the second leading cause of cancer-related deaths in the United States. While colorectal cancer is a serious disease, the good news is that it is also highly preventable and treatable when detected early. One of the most effective ways to reduce the risk of colorectal cancer is through regular colonoscopy screenings.

Why Colonoscopies Are Essential

A colonoscopy is a screening procedure that allows doctors to examine the colon and rectum for abnormal growths, such as polyps that could develop into cancer. This procedure is unique because it is both diagnostic and therapeutic—if polyps are found during the screening, they can often be removed on the spot, preventing them from turning into cancer.

“Colorectal cancer is an aggressive cancer, but it is preventable,” said Mohamed Azab, MD, a gastroenterologist with GI of Norman - Moore. “It is rare to get colon cancer if you are getting appropriate screening.”

Despite its effectiveness, many people delay or avoid getting a colonoscopy, often due to fear, lack of symptoms, or misunderstanding the process. However, delaying screening could mean detecting cancer at a later stage, when treatment is more challenging.

When Should You Get a Colonoscopy?

The American Cancer Society recommends:

• Routine colonoscopies starting at age 45 for those at average risk.
• Earlier screenings for individuals with a family history of colorectal cancer or inflammatory bowel disease (such as Crohn’s disease or ulcerative colitis).
• Follow-up screenings are based on previous colonoscopy findings and your doctor’s recommendations.

Types of Colorectal Cancer Screenings

There are multiple screening options for colorectal cancer, but a colonoscopy is the most effective because it allows for the detection, diagnosis, and removal of precancerous growths in a single procedure. Other screening options include:

• Stool Test (Fecal Immunochemical Test - FIT): A non-invasive test that checks for microscopic blood in the stool.
• Cologuard: A DNA-based stool test that detects genetic markers associated with colorectal cancer.
• If a stool test or Cologuard detects abnormalities, a follow-up colonoscopy is required to investigate further and remove potential polyps.

What to Expect During a Colonoscopy

A colonoscopy is a safe and routine procedure that typically takes 30-60 minutes. Here’s what you can expect:

• Sedation for Comfort: Patients receive light sedation to ensure they are relaxed and pain-free.
• Examination: A thin, flexible tube with a camera is inserted into the colon to look for polyps, inflammation or abnormalities.
• Possible Polyp Removal: If polyps are detected, they can often be removed immediately during the procedure.
• Recovery: Patients rest briefly after the procedure before heading home—since sedation is used, a driver is required for transportation.

“Colonoscopies are heavily studied, very safe procedures,” Dr. Azab said. “They are always done with sedation; all it takes is a day off work.”

The Colonoscopy Prep: What You Need to Know

Proper preparation is key to a successful colonoscopy. Preparation typically includes:

• Dietary Changes: Patients switch to a low-fiber diet a few days before the procedure.
• Clear Liquid Diet: The day before their colonoscopy, patients can only consume clear liquids (broth, clear juice, sports drinks).
• Bowel Preparation: Patients are prescribed to ingest a laxative solution leading up to their colonoscopy to cleanse the colon for accurate examination.
• Medication Adjustments: Certain medications, including blood thinners or GLP-1 medications (such as Ozempic, Wegovy, etc…), may need to be adjusted—consult your doctor for guidance.

Why You Shouldn’t Delay Your Screening

Many people put off getting a colonoscopy due to fear or inconvenience, but early detection can save lives. A colonoscopy not only detects colorectal cancer early, but also prevents it, by removing precancerous growths before they turn into cancer.

• Reduces the risk of developing colorectal cancer.
• Allows for early treatment, leading to better outcomes.
• Is a quick and painless procedure with minimal downtime.
