What causes adenomas in the colon?
An adenomatous polyp, also known as an adenoma, is an abnormal growth that can form on the lining of the colon (large intestine). Most of these growths are benign (noncancerous) and do not cause symptoms. There are numerous causes of colon polyps, among them genetics, age, ethnicity, and smoking.
How long does it take for an adenoma polyp to become cancerous?
Colon cancer, or cancer that begins in the lower part of the digestive tract, usually forms from a collection of benign (noncancerous) cells called an adenomatous polyp. Most of these polyps will not become malignant (cancerous), but some can slowly turn into cancer over the course of about 10-15 years.

The basic difference between a benign tumor and a cancer is its slower growth and lower capacity to spread. In other words adenomas are much less aggressive in terms of growth than adenocarcinomas.
What is tubular adenoma?
Outlook. What is a tubular adenoma? An adenoma is a type of polyp, or a small cluster of cells that forms on the lining of your colon. When doctors look at an adenoma under a microscope, they can see small differences between it and your colon’s normal lining. Adenomas typically grow very slowly and look like a small mushroom with a stalk.
Why are polyps called tubulovillous adenomas?
Sometimes doctors refer to polyps as being tubulovillous adenomas because they have features of both types. Most small adenomas are tubular, while larger ones are typically villous. An adenoma is considered small when it’s less than 1/2 inch in size. Villous adenomas are more likely to turn cancerous.
Can adenomas turn into cancer?
But sometimes cancer can develop in an adenoma if it isn’t removed. If adenomas become cancerous, they’re referred to as adenocarcinomas. Less than 10 percent of all adenomas will turn into cancer, but more than 95 percent of colon cancers develop from adenomas.

What is a colonic adenomas?
Colonic adenomas are raised protrusions of colonic mucosa, i.e., polyps formed by glandular tissue. Although a tumor of benign nature, these adenomas are usually considered precancerous and can transform into malignant structures, in contrast to hyperplastic polyps, with no malignant potential.
Which type of colonic adenomas are most likely to be cancerous?
Tubular adenomas are the most common type of colonic adenomas, comprising a prevalence of more than 80%. Although villous adenomas are more likely to become cancerous, this reflects the fact that they generally have the largest surface area due to their villous projections.
What is tubular adenomas?
If these tumors remain untreated, they can develop into colon or rectal cancer. Tubular adenomas are considered “pre-malignant” tumors. This means that these tumors may turn malignant with time. Most of these tumors are first noticed during a screening ...

Overview
An adenoma is a benign (noncancerous) tumor. Adenomas start in the epithelial tissue, the tissue that covers your organs and glands. These tumors grow slowly and look like small mushrooms with a stalk.
Symptoms and Causes
Often, the exact cause of an adenoma is unknown. Factors that can affect your risk of adenomas include:
Diagnosis and Tests
To diagnose an adenoma, your healthcare provider will complete a physical exam and medical history. You may also need one or more imaging tests, such as a CT scan, MRI scan or PET scan.
Management and Treatment
If an adenoma is small and not causing any health complications, your healthcare provider may recommend a “wait-and-see” approach. With this approach, also called surveillance, you don’t get treatment right away. Instead, you follow up periodically with your healthcare provider.
Prevention
Some risk factors for adenomas are not controllable. However, you can improve your chances of staying healthy by getting regular health screenings. If you have a higher risk of developing an adenoma, ask your healthcare provider how often you should receive screenings.
