Colonoscopy screening is a procedure used to detect any abnormalities in the large intestine (colon). It is one of the most important tests used to diagnose and prevent colorectal cancer. This procedure involves using a colonoscope—a flexible tube with a miniature camera mounted on the end—to examine the inside of the colon. The procedure is performed by a gastroenterologist, a doctor who specialises in digestive health.

The primary purpose of colorectal cancer screening in Singapore is to detect abnormal growths in the colon, such as polyps or malignancies. Polyps are small growths that can become cancerous if left untreated, and malignancies are malignant tumors. Colonoscopy can also be used to detect other digestive problems, such as ulcerative colitis or diverticulitis.

Colonoscopy is considered the gold standard for colorectal cancer screening and prevention. It is recommended that everyone over the age of 50 have a colonoscopy every 10 years. People with a higher risk of colorectal cancer, such as those with a family history of the disease, should talk to their doctor about having the procedure done more often.

The preparation for a colonoscopy is important and involves drinking a special solution to clear out the bowels. This is done the day before the procedure, and it is important to follow the instructions given by the doctor. On the day of the procedure, the patient is sedated, and the procedure is done with relative ease.


After the procedure, the patient may have some mild abdominal cramping or bloating and may need to take it easy for the rest of the day. Most people can return to their normal activities the next day. The results of the colonoscopy are typically sent to the doctor within a few days.

Therefore, colorectal cancer screening in Singapore is an important procedure for cancer prevention and detection. It is safe, effective, and relatively easy to do. It is important that everyone over the age of 50 get screened regularly to reduce their risk of developing colorectal cancer. If you have any questions about the procedure, talk to your doctor.
