Tubular Adenomatous Polyps
The most common of the adenomatous colonic polyps is the tubular adenoma. These adenomatous polyps have a tube-like shape (hence the name) and can form in any location within the colon.
Tubular adenomatous polyps are the least likely adenomas to develop into malignant colon cancer. In general, though, adenomatous polyps do carry a significant risk of becoming cancerous.
