Colonoscopy screening is a vital procedure that allows doctors to examine the colon and rectum for signs of abnormalities, including polyps and cancer. In Singapore, where colorectal cancer is one of the leading cancers among men and women, regular colonoscopy screenings play a crucial role in early detection and prevention. This guide covers what colonoscopy involves, why it’s essential, and how to prepare for and access screening in Singapore.

What is a Colonoscopy?

A colonoscopy is a diagnostic procedure performed by a gastroenterologist using a flexible tube with a camera at the end (colonoscope). The colonoscope is inserted into the rectum and allows the doctor to visualize the colon’s inner lining. During the procedure, the doctor can detect and even remove polyps, which may be pre-cancerous, and perform biopsies on any suspicious tissue.

Why Colonoscopy Screening is Important

Colonoscopy Screening is highly recommended for individuals at risk of colorectal cancer or those experiencing symptoms such as:

Unexplained weight loss
Blood in stool
Persistent abdominal discomfort
Changes in bowel habits
Regular screenings help in the early detection of colon cancer when it’s most treatable. Polyps and early-stage cancers often have no symptoms, making screening essential for catching these issues early.

Who Should Get a Colonoscopy in Singapore?

Average-Risk Individuals: In Singapore, the Ministry of Health recommends that individuals aged 50 and above undergo a colonoscopy every 10 years if they are at average risk of colorectal cancer.
High-Risk Individuals: Those with a family history of colorectal cancer, inflammatory bowel disease, or a history of polyps may need to begin screening earlier and may require more frequent monitoring, usually starting at age 40 or even earlier.
Symptomatic Individuals: Regardless of age, anyone experiencing symptoms suggestive of colon issues should consult a doctor for evaluation, which may include a colonoscopy.
Preparing for a Colonoscopy

Preparing for a colonoscopy typically involves a bowel cleanse to empty the colon. Patients are usually given instructions to:

Modify Diet: A low-fiber diet is recommended a few days before the procedure, followed by a clear liquid diet 24 hours before.
Bowel Prep Medication: Patients are instructed to take a laxative or bowel prep solution the day before the exam, which clears the colon for better visualization.
Medication Adjustments: Patients taking medications, especially blood thinners, should consult their doctor about any necessary adjustments before the procedure.
What to Expect During the Procedure

A colonoscopy generally takes 20 to 30 minutes and is conducted under mild sedation to ensure patient comfort. During the procedure:

Sedation: Patients are given sedatives to relax and minimize discomfort.
Procedure: The doctor will guide the colonoscope through the rectum to the colon, examining the lining and removing any polyps or abnormal tissue.
Recovery: Patients are monitored post-procedure as the sedative wears off, and most can go home the same day.
Where to Get a Colonoscopy in Singapore

Singapore has several options for colonoscopy screenings:

Public Hospitals: These include Singapore General Hospital (SGH), Tan Tock Seng Hospital (TTSH), and National University Hospital (NUH), which offer reliable and affordable screening services.
Private Hospitals and Clinics: Facilities like Mount Elizabeth Hospital, Gleneagles Hospital, and private gastroenterology clinics offer flexible scheduling and shorter wait times.
Cost of Colonoscopy Screening in Singapore

The cost of a colonoscopy in Singapore varies:

Public Hospitals: At public hospitals, the cost may range from SGD 800 to SGD 1,500. Patients can use Medisave to offset up to SGD 1,250 of the cost, and additional subsidies may apply for Singapore citizens.
Private Clinics: At private clinics, the cost ranges from SGD 1,500 to SGD 3,000, depending on the clinic and the complexity of the procedure. Many private insurance plans cover part or all of the cost, so it’s advisable to check with your insurance provider.
Risks and Considerations

While colonoscopy is a safe procedure, some risks exist, including bleeding, particularly if polyps are removed, and rare complications such as perforation of the colon. The chance of complications is very low, and the benefits of early detection far outweigh these risks. Singaporean healthcare facilities maintain high safety standards, making complications even less likely.
