Colon Polyps

Most colon cancers start as polyps. The good news: they're slow.

Polyps grow quietly for years before they have a chance to become cancer. Catching and removing them early is what makes screening so effective.

A colon polyp is a small growth on the inner lining of the colon or rectum. Most are harmless. Some can become cancerous over time. Because polyps usually develop without any warning signs, regular screening is the most reliable way to find and remove them before they turn into something serious.

Why Screening Works So Well

The reason colon cancer screening is one of the most effective preventive measures in medicine is timing.

7 to 10 years

The typical window between when a polyp first forms and when it could become cancer. That's a long time to find it, remove it, and prevent the cancer entirely.

Symptoms (When They Appear)

Most colon polyps cause no symptoms at all, which is exactly why screening matters. When they do produce signs, they may include rectal bleeding, abdominal pain, changes in bowel habits, changes in stool color, or mucus in the stool. Iron-deficiency anemia from chronic, unnoticed bleeding is another possible sign.

Because these symptoms overlap with many other conditions (hemorrhoids, IBS, infections, and others), they aren't reliable on their own. Screening remains the only way to detect the silent ones in time.

Tipos de pólipos de colon

Polyps fall into two main groups based on whether they have potential to become cancerous over time.

Non-neoplastic polyps

Generally benign, low cancer risk

Low risk

Hyperplastic polyps, inflammatory polyps

Carry little cancer risk. Often biopsied to confirm type, but typically don't require aggressive follow-up.

Neoplastic polyps

Variable risk, always monitored

Higher risk

Tubular adenomas, tubulovillous adenomas, villous adenomas, sessile serrated adenomas

Have higher potential to become cancerous over time. Always removed when found, with follow-up intervals based on size, number, and pathology.

Adenomas account for the majority of polyps detected on screening. Most are not cancerous when found, but their potential is exactly why removal and surveillance matter.

How Polyps Are Diagnosed

Most polyps are found during routine screening, not because of symptoms. A few different tests can detect them.

Colonoscopia

The gold standard. A flexible scope provides a direct view of the entire colon, and Dr. Chung can remove polyps and biopsy tissue during the same procedure.

Sigmoidoscopy

A shorter scope that examines the lower portion of the colon. Useful in some situations but doesn't see the whole colon.

CT colonography (virtual colonoscopy)

Uses CT imaging to produce detailed pictures of the colon. Can detect polyps but can't remove them, so a follow-up colonoscopy is needed if any are found.

Stool-based tests (FIT, Cologuard)

Detect signs of polyps or cancer in stool samples. Easier to do but less sensitive than colonoscopy, and a positive result still requires a follow-up colonoscopy.

If a Polyp Is Found

In most cases, polyps are removed during the same colonoscopy in which they're discovered. The tissue is sent to pathology to identify the type and check for any precancerous changes.

Based on what's found, Dr. Chung will recommend a follow-up screening interval. A small number of low-risk polyps usually means a longer interval before the next screening. Multiple polyps, larger polyps, or higher-risk pathology mean shorter follow-up intervals to make sure new polyps are caught early.

Risk Factors

Several factors raise the likelihood of developing colon polyps.

Age

Risk rises with age. Current US guidelines recommend starting screening at age 45.

Family history

A family history of colon polyps or colorectal cancer significantly raises your risk.

Personal history

If you've had polyps before, you're more likely to develop new ones.

Origen afroamericano

Higher rates of colon polyps and earlier-onset colorectal cancer.

Enfermedad inflamatoria intestinal

Long-standing ulcerative colitis or Crohn's disease elevates polyp and cancer risk.

Lifestyle factors

Smoking, heavy alcohol use, a diet high in red and processed meats, low fiber intake, sedentary lifestyle, and being overweight all contribute.

Type 2 diabetes

Linked to a moderately higher risk of polyps and colorectal cancer.

Genetic syndromes

Conditions like Lynch syndrome and familial adenomatous polyposis (FAP) carry a much higher lifetime risk and require earlier, more frequent screening.

Prevención

You can't eliminate the risk of polyps entirely, but you can lower it meaningfully.

✓Eat a fiber-rich diet with plenty of fruits, vegetables, and whole grains.

✓Limit red and processed meats.

✓Stay physically active. Regular movement reduces risk.

✓Maintain a healthy weight.

✓Don't smoke. If you do, quitting reduces risk over time.

✓Limit alcohol. Moderation matters.

✓Get screened on schedule. This is the single most effective prevention step.

Screening guidance: Average-risk adults should begin colonoscopy screening at age 45. Earlier screening is recommended if you have a family history, a personal history of polyps, or other high-risk conditions. Talk to Dr. Chung about the right schedule for you.

Schedule your colonoscopy or follow-up

Whether you're due for a routine screening or following up after a previous polyp, Dr. Chung can walk you through what's right for your situation.
