Adenomatous Polyp: What You Should Know

Adenomatous Polyp

Whether you’ve had one colonoscopy or several, you may have had a polyp removed at some point. Any polyp removed is sent to a laboratory for examination so you and your doctor can know exactly what it is and whether it has the potential to turn into cancer. If your lab report mentioned an adenomatous polyp, you may wonder what that means. Here’s what you need to know about this type of polyp.

What is an Adenomatous Polyp

Your colon, or large intestine, is a key part of your digestive system. Located in your abdomen, the colon is responsible for processing and eliminating waste from your body.

The inner lining of your colon is made up of a thin layer of cells known as the mucosa. Small growths of excess tissue, called colon polyps, can sometimes develop on this lining.

Adenomatous polyps, also known as adenomas, are a type of growth that forms on the lining of your colon. These polyps are considered precancerous, meaning they have the potential to develop into colon cancer if left untreated.

Adenomatous polyps are the most common type of polyp found during colon screenings and are particularly concerning due to their potential to turn into cancer over time.

Characteristics and Types of Adenomatous Polyps

Adenomatous polyps can vary in size and shape. They are typically classified into three types based on their appearance:

  1. Tubular adenomas, which have a tube-like structure, are the most common and least likely to become cancerous.
  2. Villous adenomas have a higher risk of becoming cancerous and have a finger-like or frond-like structure.
  3. Tubulovillous adenomas are a mix of tubular and villous structures and have an intermediate risk of cancer development.

Symptoms of Adenomatous Polyps

In many cases, adenomatous polyps do not cause any symptoms, especially when they are small. However, as they grow larger, they might cause:

  • Rectal bleeding
  • Blood in your stool or a change in stool color
  • Changes in bowel habits, such as constipation or diarrhea that lasts longer than a week
  • Abdominal pain or discomfort
  • Iron deficiency anemia, leading to fatigue and weakness due to chronic blood loss

Colon Cancer Risk

The presence of adenomatous polyps is a significant risk factor for developing colon cancer. While not all adenomas will turn into cancer, the likelihood increases with the size and number of polyps, as well as the type of adenoma. Villous and tubulovillous adenomas carry a higher risk compared to tubular adenomas.

Risk Factors for Colon Polyps

The likelihood of developing colon polyps can be influenced by various factors, including:

  • Being 45 years or older
  • Having a family history of polyps or colon cancer
  • Suffering from inflammatory bowel diseases such as ulcerative colitis or Crohn’s disease
  • Leading a sedentary lifestyle
  • Consuming a high-fat, low-fiber diet
  • Being obese
  • Using tobacco and alcohol

Colon Polyp Detection and Cancer Prevention

Regular screenings, particularly colonoscopies, are among the most effective methods for preventing colon cancer.

During a colonoscopy, doctors can detect and remove polyps immediately, significantly lowering the risk of them becoming malignant. Smaller polyps are often removed in one session, while larger or more complex ones may need additional procedures for complete removal.

Taking care of your colon health is easier than you might think. Schedule regular colonoscopies starting at age 45, eat lots of healthy food, move your body, and pay attention to early signs of trouble. These simple steps can make a big difference in keeping your colon healthy.

If you’re 45 or older or have a family history of colon polyps, don’t delay further – schedule a colonoscopy today!
