Colorectal Cancer Screening in Asia-Pacific
Understanding screening guidelines for your region.
Why Screening Matters Here
Colorectal cancer incidence has risen sharply across Asia over the past two decades, and the region now carries one of the largest case burdens in the world. In Hong Kong specifically, it’s the third most common cancer and a leading cause of cancer death. The encouraging part: most colorectal cancers begin as small polyps that take over a decade to become cancerous, which gives screening a genuinely wide window to catch and remove problems early.
Asia-Pacific Screening Guidelines
The Asia-Pacific Working Group’s updated consensus, reaffirmed in its third edition, sets out the following:
Start at age 50
Average-risk screening is recommended to begin at age 50 and continue through age 75. This aligns with when colorectal cancer risk begins to rise sharply in Asian populations, confirmed by regional colonoscopy studies.

Faecal immunochemical test (FIT)
A quantitative FIT is preferred over older guaiac-based stool tests for average-risk individuals. It’s non-invasive, done at home, and repeated every 1–2 years.

Colonoscopy
Recommended every 10 years for average-risk individuals who choose it as their primary screening method, and used as the follow-up test whenever a FIT result is positive.

Known risk factors
Advancing age, male sex, a family history of colorectal cancer, smoking, and obesity are all confirmed risk factors in Asian populations, and may mean screening should start earlier or happen more often.

Family history changes the timeline
If a first-degree relative (parent, sibling, or child) has had colorectal cancer, screening is generally recommended to start earlier than age 50. Ask your care team what timeline applies to you.

How This Works in 香港
Hong Kong has translated these regional guidelines into a subsidised local programme:
Colorectal Cancer Screening Programme (CRCSP)
Asymptomatic Hong Kong residents aged 50–75 are subsidised to undergo a FIT every two years through an enrolled primary care doctor, in line with the regional consensus. If the FIT result is positive, a subsidised colonoscopy is arranged with an enrolled specialist.
Eligibility and enrolment
Eligibility is defined by birth year and updated annually; participants must hold a Hong Kong Identity Card and be registered with the Electronic Health Record Sharing System (eHRSS) before their first consultation.
Cost
Most primary care doctor consultations and FIT screenings under the Programme carry no additional charge, and colonoscopy co-payments are capped at HK$1,000.
To check your current eligibility and enrol, visit colonscreen.gov.hk or call 3565 6288.
