Colorectal cancer is the second leading cause of cancer death in the United States when men and women are combined. In fact, the American Cancer Society estimates that about 53,000 people will die from colorectal cancer in 2024.1
But there’s good news: colorectal cancer is highly preventable with regular screening.
While a colonoscopy is often considered the gold standard, it’s not the only option. There are several less invasive screening methods available that can help detect colorectal cancer early when it’s most treatable.
The Gold Standard: Colonoscopy
Let’s be real, colonoscopies are the tried and true method for detecting colorectal cancer. They allow your doc to take a detailed look at your entire colon and rectum, and even remove any suspicious polyps on the spot.
The procedure involves inserting a long, flexible tube with a camera on the end into the rectum and through the entire colon. Patients are sedated for the procedure, which typically takes 30-60 minutes.
Colonoscopy is considered the gold standard because it can detect and remove precancerous polyps, preventing them from developing into cancer.
Studies have shown that colonoscopy reduces the risk of dying from colorectal cancer by up to 70%.(ref) However, the prep is no picnic, requiring a clear liquid diet and strong laxatives to clean out the colon, and the procedure itself isn’t exactly a walk in the park.
The Alternatives: Less Invasive Screening Methods
If the thought of a colonoscopy makes you want to run for the hills, take heart. There are several other screening options that may be a better fit for you:
- Fecal Immunochemical Test (FIT): This at-home test looks for hidden blood in your stool, which can be a sign of colorectal cancer. You simply collect a sample and send it off to the lab. Easy peasy.
- Stool DNA Test (Cologuard): Similar to FIT, this test checks for both blood and abnormal DNA in your stool. It’s a bit more comprehensive but still a breeze compared to a colonoscopy. Cologuard is recommended every 3 years.
- CT Colonography: Also known as a virtual colonoscopy, this test uses CT imaging to create a detailed view of your colon. No sedation is required, but you’ll still need to do the prep. CT colonography is recommended every 5 years.
Screening Guidelines: When to Start & How Often
The American Cancer Society recommends that people at average risk of colorectal cancer start regular screening at age 45.(ref) This is a change from the previous recommendation of age 50.
People in good health should continue screening through age 75, and those ages 76-85 should make a decision based on their preferences, life expectancy, and overall health. Screening is not recommended for those over 85.
The frequency of screening depends on the method chosen. People at increased risk, such as those with a family history of colorectal cancer, may need to start screening earlier and/or be screened more frequently.
Talk to Your Doctor
At the end of the day, the best screening method for you depends on your individual risk factors and preferences. Have an open and honest chat with your doctor about your options.
Remember, any screening is better than no screening at all. So don’t let the dread of a colonoscopy keep you from taking charge of your colorectal health. With these alternatives in your back pocket, you’ve got options.
