Colorectal cancer: Fiction vs. fact
Colorectal cancer occurs in the colon or rectum, and it remains a major health concern. The American Cancer Society estimates that in 2026, 158,850 people in the U.S. will be diagnosed with colorectal cancer and 55,230 will die from the disease. The good news? Screening can prevent colorectal cancer, and early detection dramatically improves survival. Understanding the facts could save your life.
Here are some common myths — along with the truths — you need to protect your health.
Myth 1: Colorectal cancer is rare
Colorectal cancer is the third most common cancer diagnosed in men and women worldwide. It's also the second most common cause of cancer-related fatalities.
Myth 2: Only people with a family history get colorectal cancer
Roughly one in three people who develop colorectal cancer have a family history. Having a first-degree relative, such as a parent or sibling, with colorectal cancer increases your risk. However, most new cases occur in people without a family history, and everyone's personal risk is different. Having one or many risk factors doesn't mean you'll get colorectal cancer.
Myth 3: Older white men are more at risk
The lifetime risk is one in 23 for men and one in 26 for women, so both should prioritize screening.
Additionally, Black men and women face a higher risk of developing and dying from colorectal cancer. Regardless of risk level, early detection greatly increases the chance of cure.
Myth 4: You only need a colonoscopy if you have symptoms
Colorectal cancer often develops without symptoms. Screening catches cancer early or even before it starts.
The American Cancer Society recommends screening starting at age 45 for those at average risk, which means no personal or family history of colorectal cancer and no history of inflammatory bowel disease.
Myth 5: Colonoscopies are difficult procedures
A colonoscopy isn't a long or painful procedure. The procedure itself only takes about 30 to 60 minutes. Most of its notoriety comes from the preparation beforehand, which requires you to clear your bowels. Most doctors instruct you to switch to low-fiber foods a few days before your colonoscopy and adopt a clear-liquid diet the day before. You'll also need to take laxatives before the procedure. Follow the preparation instructions carefully so your doctor doesn't miss any findings.
Myth 6: Colonoscopies are the only screening option
A colonoscopy is one way to screen for colorectal cancer, and it’s the only option that allows for removal of precancerous polyps. The U.S. Preventive Services Task Force also recommends these approaches for early detection:
- Computed tomography (CT) colonography
- Fecal immunochemical test (FIT)
- Flexible sigmoidoscopy
- High-sensitivity guaiac fecal occult blood test (HSgFOBT)
- Stool DNA-FIT
Talk to your doctor about the best approach for you.
Myth 7: Colorectal cancer is fatal
As with all types of cancer, the earlier colorectal cancer is detected, the better the outcome. When colorectal cancer is detected early, it can be cured. All stages of colorectal cancer are treatable. More than 90% of patients with localized cancer — meaning the cancer hasn't spread outside of the colon or rectum — are still alive five years after diagnosis. One-third of colorectal cancers are diagnosed at this stage.
Myth 8: Your choices don’t impact your risk of colorectal cancer
There's no singular, proven way to prevent colorectal cancer, but you can reduce your risk. Lifestyle modifications such as limiting processed meats, eating plenty of fruits and vegetables, exercising regularly, and avoiding smoking and excessive alcohol consumption can lower your risk of colorectal cancer.
