Why Colonoscopies are Important and When You Should Get One

The preparation for a standard colonoscopy may be unpleasant, but according to American Cancer Society statistics (2025) and CDC data (2024), colorectal cancer is the fourth most common diagnosed cancer and the second leading cause of cancer deaths in both men and women.

On the plus side, the ACS says colorectal cancer death rates among older adults have dropped over the last several decades due to early detection and treatment as a result of these screenings, and by changing lifestyle-related risk factors.

What is colorectal cancer?

Also called colon cancer, the CDC describes colorectal cancer as a disease that causes cells in the rectum or colon to grow out of control.

Colorectal cancer screening can help identify the earliest signs of colon and rectal cancers by detecting polyps and cancerous masses. Unfortunately, the early stages of colon cancer will not cause symptoms – which is why screening is so important. 

When and how often should I get screened?

ACS experts say individuals at moderate risk for colorectal cancer should maintain regular colonoscopies and screenings until the age of 75 (after starting at 45), as determined in planning with their doctor. 

Seniors between the ages of 75 and 85 should talk with their doctor about whether to continue screenings. If they have a personal history of bowel disease or a family history of colorectal cancer, it may be worth considering.

 The ACS states those over age 85 should not receive colonoscopies. 

What types of colonoscopy screenings are available?

There are multiple test options for individuals, including stool-based tests which look at your DNA and blood to determine if you may have irregular colon or rectal growth.

Talk with your trusted primary care provider or an ArchWell Health doctor to discuss your options for testing based on your unique history, risk factors, and other health needs. 

What is the preparation like?

Colonoscopies may not be as uncomfortable as you may think. Doctors have improved the colonoscopy preparation process over the last decade. 

If you have not had a colonoscopy in many years, you may be surprised to hear there are more options than having to drink an entire gallon of laxative solution. New prescription and over-the-counter methods have made it easier than ever to get ready for your appointment. 

However, you should still plan for a week with little else going on – as you’ll spend several days focusing on preparation, a nearly full day of actually going for the procedure, and a recovery day or two. 

You’ll need a friend or family member to drive you there and back, so make sure to set that up when scheduling it.

Get the supplies you need for emptying your colon – per the doctor’s orders – well in advance, as the timing of what to start drinking and when to stop eating is absolutely critical. 

You will be spending a lot of time in the bathroom, so prepare accordingly. Clean the bathroom well and make sure to have comfort items on hand. 

While you may not feel pain or discomfort from the actual colonoscopy, you will probably feel fatigued and weak from not sleeping or eating.
