FAQ

Frequently asked questions.

When should I get a colonoscopy?
USPSTF and Chinese Society of Gastroenterology recommend colorectal cancer screening starting at age 45 (lowered from 50 in 2021) for average-risk adults. Earlier and more frequent if: family history of colorectal cancer or advanced adenoma at < 60; known Lynch syndrome / FAP / serrated polyposis; inflammatory bowel disease 8+ years; prior advanced adenoma or colorectal cancer. Symptoms (rectal bleeding, weight loss, anaemia, change in bowel habit) warrant diagnostic colonoscopy regardless of age.
Why China for screening?
Three reasons: (1) Cost — combined gastro + colono under $1,000 vs $3,000–$5,000 in the US; (2) AI-assisted polyp detection (Olympus Endo-AID, Wision A.I., domestic equivalents) is widely deployed at flagship centres and improves adenoma detection rate; (3) Same-trip ESD for early lesions — China is the global volume leader in endoscopic submucosal dissection, with experience that exceeds most Western centres for early gastric and colonic cancer resection.
Is the procedure actually painless?
At top centres, sedated colonoscopy is the default — propofol-based sedation, no recall of the procedure. CO2 insufflation (rather than air) reduces post-procedure cramping. Patients walk out within 60 minutes; safe to fly the next day. The discomfort is the prep — 24-hour low-residue diet + a polyethylene glycol bowel prep the evening before. Split-dose prep (half the night before, half the morning of) is standard and gives better visualization.
What does the report include?
Bilingual final report with: photographs of the entire colon and any lesions; cecal-intubation rate confirmation; Boston Bowel Preparation Score; number of polyps detected, removed, and biopsied; histology (returned in 5–7 days); risk-stratified surveillance interval per US Multi-Society Task Force / European Society of Gastrointestinal Endoscopy guidance; recommendations for any incidental findings. Ready for upload to your home-country health record.
What if a cancer or large polyp is found?
Lesion-specific pathway: small (< 5mm) hyperplastic distal colonic polyps — left or removed without specific concern; tubular adenoma — removed and surveillance per polyp number / size / pathology; large flat or sessile lesions — referred for ESD same-trip if expert is available, or scheduled for return trip; suspected cancer — biopsy + imaging staging within the same trip, MDT review, treatment planning. We coordinate the next step at the same hospital where appropriate, or refer to a specialist colorectal cancer centre.
What about FIT and stool DNA tests?
FIT (fecal immunochemical test) and stool-DNA tests are screening alternatives recommended by USPSTF for average-risk adults who refuse or can't access colonoscopy. They are widely used in China's national screening program. They miss ~10–15% of colorectal cancers and most polyps; positive results require colonoscopy follow-up. We can coordinate stool testing as a screening option but recommend colonoscopy as the gold standard if accessible.
