Colorectal cancer (cancer of the colon or rectum) is a major health concern, but it is also highly preventable. In the U.S., it is the second leading cause of cancer death, yet it is very treatable if caught early.
Guidelines now recommend that everyone at average risk start screening at age 45. Rates of this cancer are rising in younger adults, making early detection more important than ever.
You are at higher risk if you have:
| Test Type | Quality / Reliability | How Often? |
|---|---|---|
| Colonoscopy | The "Gold Standard." It finds and removes polyps during the same visit. | Every 10 years |
| Stool-DNA (Cologuard) | Tests for blood and DNA changes in your stool at home. | Every 1 to 3 years |
| FIT or gFOBT | Simple home tests that look for hidden blood in the stool. | Every year |
| Blood Tests (Shield) | Non-invasive; predicted 87.5% of non-metastatic cases in trials. | Discuss with doctor |
| CT Colonography | A "virtual" colonoscopy using X-rays to create images. | Every 5 years |
Important: If a stool or blood test comes back positive, you will need a follow-up colonoscopy to get a final diagnosis.
Many people can access no-cost preventive screenings through their insurance, as these tests are recommended by national health task forces. Home-based stool tests are often preferred by patients because they are convenient and do not require the special "prep" or fasting needed for a colonoscopy.
Choosing not to screen is dangerous because colon cancer often has no symptoms in early stages.
Don't wait for symptoms like bloody stools or stomach pain. Talk to your doctor today about which test is right for you.
