Dysplasia is important because it is a precancerous change that can become cancerous over time. What does dysplasia mean and why is it important in a tubular adenoma?Īll tubular adenomas show an abnormal pattern of growth called dysplasia. The glands of a tubular adenoma are seen on the right side of this image. The nuclei (the part of the cell that holds the genetic material) of the cells in the adenoma are also larger and hyperchromatic (darker) compared to the cells normally found on the inside surface of the colon. When examined under the microscope, the cells in a tubular adenoma connect together to form long, thin tube-shaped glands. What does a tubular adenoma look like under the microscope? The adenoma may be removed in one piece or in multiple pieces. The diagnosis of tubular adenoma can only be made after part, or all of the adenoma is removed and the tissue is examined under the microscope by a pathologist. How is the diagnosis of tubular adenoma made? Other types of polyps in the colon include tubulovillous adenoma, villous adenoma, and sessile serrated lesions. However, not all polyps in the colon are tubular adenomas. Because of the way they grow, tubular adenomas are a type of polyp. In pathology, the term polyp is used to describe any growth that sticks out from the surface of a tissue. What is the difference between a tubular adenoma and a polyp? However, all tubular adenomas are considered precancerous growths because they can turn into a type of colon cancer called adenocarcinoma over time. No, tubular adenoma does not mean cancer. If left untreated, all tubular adenomas are associated with an increased risk of developing a type of colon cancer called adenocarcinoma over time. It develops from the cells that cover the inside surface of these tissues.

This condition puts you at a 50 percent higher risk for developing colorectal cancer. Having multiple hyperplastic polyps in your colon is known as hyperplastic polyposis. Larger hyperplastic polyps are more likely to develop into cancer. Your risk of colon cancer is much lower if you only have one or a few of these polyps in your colon. They tend not to cause any other major health problems, either. Hyperplastic polyps rarely turn into colon cancer. What does it mean when this happens in your colon?Ī hyperplastic polyp in your colon isn’t necessarily a cause for concern.
