Understanding Colorectal Cancer: What You Need to Know
Colorectal cancer is one of the most common cancers in Singapore, affecting both men and women, especially those above the age of 50. Gaining knowledge about colorectal cancer causes, prevention strategies, symptoms, and screening options is essential for taking proactive steps to safeguard your health.
What Causes Colorectal Cancer?
Colorectal cancer typically begins as small, non-cancerous growths called polyps in the lining of the colon or rectum. Over time, some of these polyps may develop into cancer. Several factors can increase your risk, including:
- Age (risk rises sharply after age 50)
- A family history of colorectal cancer or polyps
- A diet high in red or processed meats and low in fibre
- Inflammatory bowel diseases (like Crohn’s disease or ulcerative colitis)
- Sedentary lifestyle, obesity, smoking, and heavy alcohol consumption
Understanding these colorectal cancer causes can help you make healthier lifestyle choices that reduce your risk.
How Can You Prevent Colon Cancer?
Adopting good habits is the first line of defence in colon cancer prevention. A diet rich in fruits, vegetables, and whole grains supports bowel health. Regular physical activity, maintaining a healthy weight, limiting red and processed meat, avoiding tobacco, and moderating alcohol use all contribute to a lower risk. Early detection through regular screening remains one of the most effective prevention methods.
Recognising Colon Cancer Signs and Symptoms
Colon cancer signs can be subtle or mistaken for other digestive issues in the early stages. Common warning signs include:
- Changes in bowel habits (such as persistent diarrhea, constipation, or narrowing of the stool)
- Blood in the stool or rectal bleeding
- Unexplained weight loss
- Persistent abdominal pain, cramps, or bloating
- A feeling that your bowel doesn’t empty completely
- Weakness or fatigue
If you notice any of these symptoms that last for more than a few weeks, consult your doctor promptly.
Colorectal Cancer Screening in Singapore
Screening helps detect cancer early—sometimes even before symptoms appear. Colorectal cancer screening Singapore programmes recommend that adults aged 50 and above undergo regular checks. The two main screening methods are:
- Faecal Immunochemical Test (FIT): A simple stool test that can detect hidden blood, a possible sign of polyps or cancer.
- Colonoscopy: Considered the gold standard, colonoscopy Singapore involves examining the colon and rectum with a flexible camera. It allows for removal of polyps during the procedure and is recommended every 10 years for average-risk individuals.
Early detection through screening greatly increases the likelihood of successful treatment and survival.
Conclusion
Awareness of colorectal cancer causes, monitoring for colon cancer signs, and participating in regular colorectal cancer screening in Singapore are essential steps in the fight against this disease. By embracing healthy lifestyle choices and taking part in recommended screenings—such as the FIT test and colonoscopy Singapore—you can lower your risk and improve outcomes through early intervention. Don’t wait until symptoms develop; proactive prevention and timely screening are your strongest tools for lifelong colon health.
