Colorectal Cancer Screening - Colonoscopy

Detecting Colorectal Cancer with Colonoscopy Screening


Colorectal cancer is Singapore's top killer

Colorectal cancer affects 1,865 cases each year

Colorectal cancer is one of the most common cancers in Singapore. Colorectal cancer is Singapore’s top killer, affecting more than 1,865 cases each year. This makes early detection and treatment of colon cancer essential to improve outcomes and reduce mortality rates. One of the most effective ways to detect colon cancer is through colonoscopy screening.

How Colonoscopy is done

Colonoscopy screening is a procedure in which a thin, flexible tube with a tiny camera attached to it is inserted into the colon in order to take images of the colon and rectum. This allows doctors to look for any abnormalities or early signs of colon cancer. The colonoscopy procedure can also be used to take tissue samples for further analysis, aiding in the diagnosis and treatment of colon cancer.

In Singapore, colonoscopy screening is recommended for those aged 50 years and above on a regular basis. This is because colon cancer is more common amongst older individuals and risk increases with age. Those that have a family history of colon cancer or polyps should also start colonoscopy screening before the age of 50.

About Colonoscopy Procedure

The colonoscopy procedure itself is relatively simple and safe, though it does require some preparation beforehand. Individuals need to follow certain instructions on the day prior in order to clean the colon for the best possible results from the colonoscopy. For example, individuals should avoid consuming solid food the day before and drink only clear liquids. Additionally, strong laxatives or enemas may be needed to fully clean out the colon in preparation for the colonoscopy.


Once prepared, a colonoscopy usually takes around 30 minutes to complete. The procedure is usually done under sedation. Two types of sedation are available: moderate or deep sedation. You may wish to discuss this with your Endoscopist to understand your best option.

Colonoscopy Screening for Colon Cancer

When colonoscopy screening is done regularly, it can help detect colon cancer at earlier stages when it is easier to treat and has a better prognosis. It can also reduce the risk of colon cancer by allowing doctors to identify and remove colon polyps which may turn into colon cancer if left untreated.

Overall, colonoscopy screening is an important tool in the fight against colon cancer and should be taken seriously by individuals aged 50 years or above. It can help detect colon cancer early and reduce mortality rates – making it a vital part of colorectal cancer detection and prevention in Singapore. If you are aged 50 years or above, speak to your doctor about colonoscopy screening and ensure that you receive regular screenings as recommended.

By being proactive with colonoscopy screening, we can help reduce the prevalence of colon cancer and make a positive difference in the fight against this common form of cancer. Make sure to get colonoscopies regularly and practice good health habits, like eating a balanced diet and exercising regularly. Doing so can help reduce the risk of colon cancer and ensure that you can enjoy better health in the long run.
