Colon polyps are a common finding during routine colonoscopies, and while the term “polyp” may sound concerning, most are benign (non-cancerous). Still, some types can develop into colon cancer over time — which is why awareness and screening are so important. Understanding what colon polyps are, who is at risk, and how they are treated is essential to preventing colon cancer before it starts.
What are Colon Polyps?
A colon polyp is a small grown on the inner lining of the colon or rectum. Polyps vary in size and shape — some stay tiny, while others can grow larger over time. Although many polyps are harmless, certain types of polyps have the potential to become cancerous if they aren’t removed and are left untreated.
Types of Polyps
Hyperplastic Polyps
Hyperplastic polyps are small, noncancerous growths that arise from the lining of the large intestine (colon). They are usually very small and are generally considered benign, meaning they are not typically associated with an increased risk of colon cancer. Because of their low-risk nature, they usually do not require the same level of surveillance as other polyp types.
Adenomatous Polyps
Adenomas are the most common type of polyp — and the type most likely to become cancerous over time. These growths arise from the colon lining and are considered precancerous, meaning they can develop into cancer if not removed. While they may not pose an immediate risk, removing them prevents possible progression to cancer. There are several types of adenomatous polyps, including tubular adenomas, villous adenomas, and tubulovillous adenomas. Adenomas require close monitoring and follow-up.
Sessile Serrated Polyps (SSP’s)
Sessile serrated polyps also arise from the colon lining and are considered precancerous. They have a higher risk of developing into colon cancer and often require careful monitoring. Because they can be flatter and harder to detect, high-quality screening is important, and an excellent bowel prep is also needed.
What Causes Colon Polyps and Who Is at Higher Risk?
The exact cause isn’t always clear, but several factors can increase your risk, and certain people are more likely to develop colon polyps or colon cancer, including:
- Adults age 45 and older (risk rises after 45)
- Individuals with a family history of colon polyps or colon cancer
- People with hereditary syndromes (e.g., Lynch syndrome, Familial Adenomatous Polyposis, APC gene mutation)
- Anyone with long-standing chronic conditions like ulcerative colitis or Crohn’s disease
- African Americans, who have a higher risk and should consider earlier screening. African Americans are about 20% more likely to get colon cancer and about 40% more likely to die from it than most other groups.
- People with lifestyle risks such as smoking, obesity, high-fat diets, low fiber intake, inactivity, or heavy alcohol use
Knowing your risk can help determine when to begin screening and how often.
Symptoms to Watch For
Most colon polyps cause no symptoms at all, which is why routine screening is essential! If symptoms do appear, they may include:
- Rectal bleeding
- Blood in the stool
- Changes in bowel habits
- Abdominal discomfort (less common)
Even with subtle or no symptoms, dangerous polyps can still be present — screening colonoscopy is the only way to detect them early.
The Importance of Screening
Colonoscopy is the most effective way to detect and remove colon polyps before they turn into cancer. Eliminating precancerous polyps dramatically lowers your risk of colon and rectal cancer.
Most adults should begin screening at age 45, or earlier if they have symptoms, risk factors or a family history of colon cancer.
How Often Should You Get Screened?
General guidelines include:
- Average-risk adults: Start at age 45, then every 10 years if no polyps are found.
- Those with adenomas or serrated polyps: Follow-up timing depends on the number, size, and type of polyps (often every 3-5 years).
- Higher-risk individuals: May need earlier and more frequent screening as recommended by a doctor.
Always follow personalized guidance from your healthcare provider.
How Polyps are Treated
The good news: most polyps can be removed during the colonoscopy, a quick and minimally invasive procedure, using special tools. This process is quick and painless for the patient.
Once removed, the polyp is sent to a lab to determine its type and whether you’ll require closer follow-up.
Prevention Tips
While not all polyps can be prevented, healthy habits can help lower your risk:
- Eat a balanced, fiber-rich diet
- Limit red and processed meats
- Exercise regularly
- Maintain a healthy weight
- Avoid smoking
- Limit alcohol
- Stay up to date with recommended screening colonoscopy
Take Charge of Your Colon Health
Colon polyps are common — but colon cancer is one of the most preventable cancers. Regular timely screenings is the key to early detection, effective treatment, significantly reduce your risk and peace of mind.
If you’re 45 or older, or have a family history of colon cancer, talk to your doctor about scheduling a colonoscopy.
Your future health is worth it.
Why Colonoscopy Matters
A colonoscopy is the most effective tool for detecting and removing polyps before they turn into cancer. In fact:
- More than 90% of colorectal cancers begin as polyps.
- A colonoscopy can detect and remove polyps which reduces the risk of developing — and dying from —colon cancer by up to 69%.
- Removing precancerous polyps dramatically lowers long-term risk.
Polyp detection and removal during colonoscopy is one of the most powerful tools for preventing colon cancer. A colonoscopy doesn’t just find cancer — it prevents it.
