Colorectal Cancer Screening

Colorectal cancer is one of the most common cancers worldwide, yet it is also one of the most preventable. The reason is simple but powerful: when we find changes in the colon early — sometimes before cancer even develops — we can treat them successfully. At Phoenix Gastroenterology & Health Services in Kingston, we want every Jamaican to understand that screening is not something to fear. It is one of the smartest, most life-protecting decisions you can make for your health.

What Is Colorectal Cancer?

Colorectal cancer affects the colon (the large intestine) or the rectum. Most cases begin as small growths called polyps on the inner lining of the bowel. Polyps are usually harmless at first, and many never become cancer. But over several years, some can slowly turn into cancer.

This slow progression is exactly why screening works so well. If we find and remove a polyp before it becomes dangerous, we stop cancer from ever starting. If cancer has already begun, finding it early — before it spreads — gives the best possible chance of a full recovery.

Why Screening Matters So Much

Many people put off screening because they feel perfectly healthy. That is understandable, but it is also the heart of the problem. Early colorectal cancer often causes no symptoms at all. By the time warning signs appear, the disease may be more advanced and harder to treat.

Screening looks for problems before you feel sick. It can:

• Detect and remove polyps before they become cancer
• Catch cancer at an early, highly treatable stage
• Dramatically improve survival and quality of life
• Bring peace of mind when results are normal

Why This Is Especially Important for Jamaicans

Research consistently shows that people of African descent tend to develop colorectal cancer earlier and are more likely to be diagnosed at a later, more serious stage. Several factors contribute, including differences in access to screening and how the disease behaves.

For our Jamaican community, this means screening is not just routine — it is genuinely protective. We also see local lifestyle patterns that can raise risk, such as diets high in processed and salted meats, low fibre intake, limited physical activity, and rising rates of obesity and diabetes. None of these guarantee cancer, but together they make regular screening even more worthwhile.

Who Should Be Screened — and When?

For most people at average risk, screening should begin at age 45. You may need to start earlier, or screen more often, if you have:

• A parent, brother, or sister who had colorectal cancer or polyps
• A personal history of polyps or inflammatory bowel disease (such as Crohn’s disease or ulcerative colitis)
• Certain inherited conditions that run in families
• Symptoms that need investigation regardless of age

If colorectal cancer runs in your family, speak with us. We may recommend starting around age 40, or ten years before the age your relative was diagnosed — whichever comes first.

Don’t Ignore These Warning Signs

Screening is for people without symptoms. But if you notice any of the following, see a doctor promptly, no matter your age:

• Blood in the stool or bleeding from the rectum
• A lasting change in bowel habits (diarrhoea, constipation, or narrow stools)
• Ongoing abdominal cramping, discomfort, or bloating
• Unexplained weight loss or persistent tiredness
• A feeling that the bowel doesn’t empty completely

These symptoms do not always mean cancer — they are often caused by something far less serious. But they should always be checked.

What Are the Screening Options?

There is no single “right” test for everyone. The best test is the one that gets done. Common options include:

Colonoscopy

Considered the gold standard. A thin, flexible camera examines the entire colon. Its great advantage is that polyps can be found and removed during the same procedure. If your colonoscopy is normal, you typically won’t need another for about ten years.

Stool-Based Tests

These check a stool sample for hidden blood or abnormal DNA. They are simple and done at home, but must be repeated more often, and any abnormal result must be followed by a colonoscopy.

During your visit, we will help you choose the option that fits your risk level, your comfort, and your circumstances.
