9. Accuracy of the test
Virtual colonoscopy has been shown to detect large polyps (greater than 10 millimeters) and colorectal cancers with accuracy comparable to traditional colonoscopy. However, its sensitivity decreases for smaller polyps under 6 millimeters, which may sometimes be missed.
This difference in detection rates means that while virtual colonoscopy is effective for screening, it is not a substitute for traditional colonoscopy if polyps are found or if symptoms suggest colorectal cancer.
10. When to seek medical care
After your virtual colonoscopy, contact your healthcare provider immediately if you experience any of the following symptoms:
- Visible blood in your stool or rectal bleeding
- Dizziness or fainting
- Fever or chills
- Severe abdominal pain or persistent cramping
A note from your healthcare provider
Colorectal cancer is one of the most common cancers in adults but is highly treatable when caught early. Screening is essential, yet many avoid traditional colonoscopy due to discomfort or sedation concerns. Virtual colonoscopy offers a less invasive alternative with fewer risks and a quicker recovery, making it a viable option for many individuals.
Discuss your colorectal cancer screening options with your healthcare provider to determine if virtual colonoscopy is appropriate for you, especially if you have risk factors such as a family history or are aged 45 or older.
