Colonoscopy

Early Detection of Colon Cancer

A colonoscopy can detect early signs of colorectal cancer, increasing the chances of successful treatment.

Decreased Risk for Colon Cancer

By identifying and removing precancerous polyps, a colonoscopy can effectively reduce the risk of developing colon cancer.

Improved Diagnosis

A colonoscopy provides a clear visualisation of the colon, which aids in diagnosing gastrointestinal diseases.

Detection of Other Illnesses

A colonoscopy can also detect other issues, such as diverticula (pouches along the colon) and signs of inflammatory bowel disease.

Treatment and Prevention

A unique advantage of a colonoscopy is its ability to treat certain abnormalities on the spot, such as removing polyps.

High Accuracy

A colonoscopy is known for its high accuracy in detecting abnormalities in the colon.

Colorectal Cancer

A colonoscopy is one of the most effective ways to detect early stages of colorectal cancer. It can identify small polyps (abnormal growths), which could, over time, develop into cancer.

Inflammatory Bowel Disease (IBD)

Inflammatory bowel diseases, such as Crohn's disease and ulcerative colitis, cause chronic inflammation in the digestive tract. A colonoscopy can detect signs of these conditions, including ulcers, inflammation, and bleeding.

Diverticulosis and Diverticulitis

These conditions occur when small pouches (diverticula) form in the colon's walls and become inflamed or infected. A colonoscopy can reveal these pouches and assess their condition.

Gastrointestinal Bleeding

Unexplained bleeding in the digestive tract can often be traced back to the colon or rectum through a colonoscopy.

Irritable Bowel Syndrome (IBS)

Although a colonoscopy cannot directly diagnose IBS, it can rule out other conditions like IBD or cancer that might mimic IBS symptoms.

Age

In Singapore, routine colonoscopies are recommended for individuals aged 50 and above. Earlier screening is recommended for higher-risk individuals.

Family History

If you have a family history of colorectal cancer or polyps, you may need to start screening earlier. The usual recommendation is to have your first colonoscopy at age 40 or 10 years before the age at which your family member was diagnosed.

Symptoms

If you are experiencing rectal bleeding, persistent abdominal pain, unexplained weight loss, or changes in bowel habits, a colonoscopy can help diagnose the cause.

Previous Polyps or Colorectal Cancer

Individuals who have had polyps or colorectal cancer in the past are more likely to develop these conditions again.

Medication Adjustment

You may be advised to temporarily stop taking certain medications which may pose risks to the procedure.

Dietary Restrictions

You may be asked to limit or avoid solid foods for a few days before the test.

Colon Cleansing

You will need to take a strong laxative so that your doctor can view and access the entirety of your colon during the procedure.

Sedation

Before the procedure starts, you will be given a sedative to help you relax and not feel any discomfort during the procedure.

Insertion of the Colonoscope

The doctor will insert the colonoscope into your rectum. The scope has a light and a camera on one end that displays images on a monitor.

Inspection

The doctor carefully inserts the colonoscope to inspect the lining of your colon. Air or carbon dioxide will be introduced through the scope to inflate the colon for better visibility.
