What if my report used the term "sessile"? These growth patterns are mostly used to try and determine how often you will need to have colonoscopy to make sure you don't develop colon cancer in the future (see FAQ#10). As long as your polyp has been completely removed and does not show cancer, you do not need to worry about the type of growth pattern seen in your polyp. Adenomas with a villous growth pattern are also more likely to have cancers develop in them. Larger adenomas are more often found to have cancers developing in them.
Larger adenomas may have a villous growth pattern. Most adenomas that are small (less than ½ inch) and have a tubular growth pattern. Because many adenomas have a mixture of both growth patterns, some polyps may be called tubulovillous adenomas. There are two major growth patterns: tubular and villous. What are "tubular adenomas", "tubulovillous adenomas", and "villous adenomas"?Īdenomas have several different growth patterns that can be seen by the pathologist under the microscope. What is an adenoma?Īn adenoma is a polyp that resembles the normal lining of your colon but differs in several important microscopic aspects. What is a polyp in the colon?Ī polyp is a projection (growth) of tissue from the inner lining of the colon into the lumen (hollow center) of the colon. The colon ends at the rectum and waste exits through the anus. The ascending colon, transverse colon, descending colon, sigmoid colon, and rectum are, in order other parts of the colon beyond the cecum. The cecum is the beginning of the colon where the small intestine empties into the large intestine. What if my report mentions "cecum", "ascending colon", "transverse colon", "descending colon", "sigmoid colon", or "rectum"? This FAQ sheet is designed to help you understand the medical language used in the pathology report. The pathology report tells your treating doctor the diagnosis in each of the samples to help manage your care.
When your colon was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist.
