Colorectal cancer is often called a “silent killer” because it can develop quietly without noticeable symptoms until it reaches an advanced stage. In fact, many people do not realise they have it until it is too late, making it the second leading cause of cancer-related deaths worldwide and also in Singapore for the period 2018-2022, according to the Singapore Cancer Registry Annual Report 2022. The good news? Early detection saves lives. When caught early, colorectal cancer has a survival rate of over 90%. But if you wait for symptoms of colorectal cancer to appear, your chances may decrease significantly.

Why Symptoms Are A Late Warning Sign
Colorectal cancer develops slowly over time, often starting as small, non-cancerous growths in the colon or rectum called polyps. These polyps can take years to become cancerous—and they rarely cause symptoms in the early stages.
By the time you notice:
- Blood in your stool (bright red or dark)
- Unexplained weight loss
- Persistent abdominal discomfort (cramps, gas, pain)
- Changes in bowel habits (diarrhea, constipation, or narrowing of the stool)
…the cancer may have already spread beyond the colon.
Who Is At Risk?
Colorectal cancer is not just an “older person’s disease.” While your risk increases after age 50, cases are rising among younger adults. Risk factors include:
- Family history of colorectal cancer or polyps
- Diet high in red or processed meats
- Smoking and heavy alcohol use
- Inflammatory bowel diseases (e.g., Crohn’s disease, ulcerative colitis)
- Obesity and lack of physical activity
Even without risk factors, everyone over 50 should start regular screening.
How Screening Saves Lives
Regular screenings can detect colorectal cancer early—or prevent it altogether. Screenings find precancerous polyps, allowing doctors to remove them before they turn into cancer.
Types Of Colorectal Cancer Screening:
- Colonoscopy: The gold standard. Detects and removes polyps in one procedure.
- Fecal Immunochemical Test (FIT): A non-invasive stool test that checks for hidden blood.
- CT Colonography (Virtual Colonoscopy): A less invasive imaging option.
According to the CDC, screening reduces colorectal cancer deaths by up to 68% when done regularly.

FAQs About Colorectal Cancer Screening
Q: Is a colonoscopy painful?

Q: I have no symptoms. Do I still need screening?
A: Yes! The goal is to catch cancer before symptoms develop.
Q: How often should I get screened?
A: Every 10 years for colonoscopy if normal, but it may vary based on personal risk factors.
