When people hear the word “polyp” during a colonoscopy, it often sparks worry, especially because colon cancer is a major health concern. But here’s the truth: not all colon polyps are cancerous, and many can be removed safely before they ever become a problem.
At GI Partners of Illinois, our gastroenterologists perform routine colon screenings and polyp removals to help prevent colorectal cancer and keep your digestive health in check. Let’s break down what colon polyps are, why they form, and when you should be concerned.
What Are Colon Polyps?
Colon polyps are small growths that develop on the inner lining of the large intestine (colon). They’re quite common, especially in adults over 50, and most are benign (noncancerous).
However, some types of polyps can gradually develop into cancer if left untreated. That’s why early detection and removal are so important.
Types of Colon Polyps
There are several types of polyps, and understanding the difference can help you know your risk level:
Adenomatous Polyps (Adenomas)
These are the most common and are considered precancerous. While not all adenomas turn into cancer, most colon cancers start as adenomatous polyps.
Hyperplastic Polyps
Usually small and harmless, these are often found in the lower part of the colon. They rarely become cancerous.
Serrated Polyps
Some serrated polyps, especially larger ones located in the upper colon, can become precancerous and may require closer monitoring.
Are Colon Polyps Always Cancerous?
No, in fact, most colon polyps are not cancerous. But because certain types can turn into cancer over time, identifying and removing them early is key.
The transformation from a benign polyp to cancer is typically slow, often taking 10 to 15 years. This means regular screening gives doctors plenty of time to detect and remove them before they cause harm.
What Causes Colon Polyps?
Several factors can increase your risk of developing colon polyps:
- Age (especially 50+)
- Family history of colon polyps or colorectal cancer
- A diet high in red or processed meats
- Smoking and alcohol use
- Obesity or a sedentary lifestyle
- Inflammatory bowel diseases (like Crohn’s or ulcerative colitis)
While you can’t change your genetics or age, you can reduce risk with healthy lifestyle choices and regular screenings.
How Are Polyps Detected and Treated?
The most effective way to detect and remove colon polyps is through a colonoscopy. During the procedure:
- Your gastroenterologist examines the entire colon.
- If a polyp is found, it’s usually removed immediately.
- The tissue is sent to a lab for analysis to determine whether it’s benign, precancerous, or cancerous.
At GI Partners of Illinois, our specialists perform minimally invasive procedures with precision and care — ensuring patient comfort and peace of mind.
Why Early Detection Matters
Colon cancer is one of the most preventable cancers, largely thanks to colonoscopies. When detected early, the survival rate for colorectal cancer exceeds 90%.
Routine screening starting at age 45 (or earlier for those with risk factors) can literally save your life.
When to See a Gastroenterologist
You should schedule an appointment if you experience:
- Rectal bleeding
- Changes in bowel habits
- Unexplained weight loss
- Abdominal pain or cramping
- Family history of colorectal cancer
Even if you feel fine, preventive colon screenings are still essential — especially if you’re over 45.
