The Importance of Colonoscopies: What You Need to Know

What is a Colonoscopy and Why does it Matter?

Colonoscopies remain the gold standard for colorectal cancer screening. In 2025, the importance of early detection is greater than ever. Colorectal cancer is the second leading cause of cancer deaths in the U.S., yet it’s also one of the most preventable and treatable if caught early.

A colonoscopy allows doctors to inspect the inner lining of your colon and rectum using a flexible, lighted tube. It can detect precancerous growths (polyps) that can be removed before they turn into cancer, as well as identify signs of other digestive issues.

When Should You Get a Colonoscopy?

As of 2025, the U.S. Preventive Services Task Force recommends that adults at average risk start screening at age 45, down from the previous age of 50. You may need to start earlier or screen more often if you:

• Have a family history of colorectal cancer or polyps

• Suffer from inflammatory bowel diseases (e.g., Crohn’s or ulcerative colitis)

• Experience symptoms like rectal bleeding, unexplained weight loss, or persistent changes in bowel habits

Most people with normal results only need a colonoscopy every 10 years.

What to Expect During the Procedure

The procedure typically lasts 30–60 minutes and is done under sedation. Preparation involves a bowel cleanse the day before—often the most dreaded part, but necessary for clear visibility.

During the exam, your doctor may remove polyps or take biopsies. Most people resume normal activities within a day.

How to Prepare for a Colonoscopy

• Follow your prep instructions carefully (dietary restrictions, clear liquids, and laxatives)

• Arrange for transportation due to sedation

• Communicate openly with your provider about medications and health history

Clear prep equals clear results, improving the exam’s accuracy.

Addressing Common Myths

• “It’s painful.” Sedation ensures most patients feel nothing during the procedure.

• “I don’t need it if I feel fine.” Colon cancer can develop silently for years.

• “It’s too expensive.” That’s where MDsave comes in.
