Colorectal cancer has become the leading cancer in Singapore, affecting both men and women. But here’s the good news—knowing the risk factors and taking charge of your health can make all the difference. Colorectal cancer starts in the inner lining of the colon and rectum, where cells are constantly regenerating. During this process, mutations can occur, which may lead to cancer. Most cases follow the adenoma-carcinoma sequence, where benign polyps (adenomas) slowly mutate into cancerous growths (carcinomas) over time.
What Increases Your Risk?
Your risk is shaped by various factors. Let’s break it down:
-
- Genetics – Only about 5% of colorectal cancer cases are linked to inherited gene mutations.

- Age – If you’re over 50, the risk goes up, but don’t let your guard down if you’re younger. About 6% of cases occur in people under 45, and 20% happen before age 55.

- Family history – Got a close family member with colorectal cancer? That could increase your chances.

- Personal history of polyps or colorectal cancer – If you’ve had polyps or previous colorectal cancer, keep a close watch! The more polyps or the younger you were at the time of diagnosis, the higher your risk.
Your Screening Options: Be Proactive!
You’ve got tools in your hands to stay ahead of colorectal cancer. Here’s a quick overview of the screening methods available:
-
- Stool occult blood test – This is a quick, non-invasive test. You provide a small stool sample, and we check it for traces of blood. It’s not 100% foolproof, but with around 70–85% accuracy, it’s a great starting point!

-
- Colonoscopy – The gold standard for screening! A flexible tube allows us to directly examine your colon. Plus, we can remove any polyps we find right then and there. You’ll likely be sedated for comfort.

- Barium enema – Think of it as a paint-by-numbers for your colon! A special dye (barium) is introduced into your colon, followed by air, and then we take X-rays to map out the internal structure.

- CT colonography (virtual colonoscopy) – Want something high-tech? This method uses a CT scan to create a 3D image of your colon after inflating it with air. It’s quick, but still accurate!
Why Early Detection is Key
Colorectal cancer is sneaky—it often doesn’t show symptoms until later stages. But the earlier you catch it, the better your chances of successful treatment. Regular screenings are your first line of defence, especially if you’re at high risk. Remember, early detection equals better outcomes!
