Adenomatous polyps are the second most common stomach polyp.
They tend to be precancerous, especially when larger than 1 centimeter in diameter. Use of this site signifies your agreement to the terms of use . A single copy of these materials may be reprinted for noncommercial personal use only. Walgreen Co. All rights reserved.
