Colorectal cancer currently stands as the second most common cancer affecting men and women in Singapore. Despite these statistics, there is a significant silver lining: it is one of the most preventable and treatable forms of cancer if it is detected early.
Undergoing colorectal cancer screening in Singapore is not merely a medical procedure; it is a proactive step towards ensuring long-term wellness for you and your family. In this article, we explore the various screening methods available locally and why timely intervention is paramount.

Why Screening Is Essential for Singaporeans
In Singapore, the risk of colorectal cancer increases significantly after the age of 50. However, recent trends indicate a rising incidence among younger adults. Most colorectal cancers begin as small growths known as polyps. These polyps are often asymptomatic, meaning they do not cause pain or visible changes in bowel habits for years.
Screening allows doctors to identify and remove these polyps before they have the chance to develop into malignancy. When detected at stage I, the survival rates for men and women are around 84% and 86% percent respectively.
Colorectal Cancer Screening in Singapore
Singapore’s healthcare system offers several robust methods for screening. The choice of test often depends on your age, risk factors, and personal preference.
1. Faecal Immunochemical Test (FIT)
The FIT is the most common preliminary screening tool used in Singapore. It is a simple kit that detects trace amounts of blood in the stool, which may be a sign of polyps or cancer.
- Suitability: Individuals at average risk with no symptoms.
- Frequency: Recommended annually.
- Benefit: Non-invasive and can be performed in the privacy of your home.
- Cost: S$25 to S$55
2. Colonoscopy
Often regarded as the “gold standard” for colorectal cancer screening, a colonoscopy involves a specialist using a thin, flexible tube with a camera to examine the entire colon.
- Suitability: Individuals aged 50 and above, or those with a family history of colorectal cancer.
- Frequency: Once every 10 years if the results are normal.
- Benefit: This is both a diagnostic and a therapeutic tool. If a doctor finds a polyp during the procedure, they can remove it immediately, effectively preventing cancer from starting.
- Cost: Colonoscopy Cost Comparison
3. Computed Tomography (CT) Colonography
Also known as a “virtual colonoscopy,” this method uses CT scans to produce 2D and 3D images of the colon and rectum.
- Suitability: For patients who may not be fit for a traditional colonoscopy or those with certain medical contraindications.
- Frequency: Every 5 years.
When Should You Start Screening?
The Ministry of Health (MOH) generally recommends that Singaporeans and Permanent Residents start regular screening at age 50. However, you should consult a specialist earlier if you experience “red flag” symptoms such as:
- Persistent change in bowel habits (diarrhoea or constipation).
- Blood in your stool (bright red or very dark).
- Unexplained weight loss.
- Persistent abdominal discomfort or bloating.

Frequently Asked Questions (FAQs)
s colorectal cancer screening covered by MediSave in Singapore?
Yes, Singaporeans and Permanent Residents can use MediSave for screening colonoscopies. Under the MediSave500 or MediSave700 scheme, a portion of the costs for diagnostic and screening endoscopies can be covered, provided the procedure is performed by an approved healthcare provider.
What is the difference between a FIT and a colonoscopy?
The FIT is a preliminary test that only detects blood in the stool and must be done yearly. A colonoscopy is a comprehensive internal examination that allows for the removal of polyps on the spot and is typically only required once every decade for average-risk individuals.
Do I need to fast before a colonoscopy?
Yes, a colonoscopy requires “bowel preparation.” This involves a clear liquid diet for a day prior and the consumption of a prescribed laxative solution to ensure the colon is clean for a clear view.
Are there risks associated with colonoscopy?
While a colonoscopy is a safe and routine procedure in Singapore, like any medical intervention, there are minor risks such as a reaction to sedation or, very rarely, a tear in the colon wall. Your specialist will discuss these risks with you during the consultation.
Can I go back to work the day after my screening?
Most patients can resume normal activities and return to work the day after a colonoscopy. Because sedation is used during the procedure, you will be advised not to drive or operate heavy machinery for at least 24 hours.
