    The remaining 10% of adenomas are larger than 1 cm and approach a 10% chance of containing invasive cancer. [17] There are three types of adenomatous polyp: Tubular adenomas (tube-like shape) are the most common of the adenomatous polyps; they may occur everywhere in the colon and they are the least likely colon polyps to develop into colon cancer

    Neoplastic polyps of the bowel are often benign hence called adenomas. An adenoma is a tumor of glandular tissue, that has not (yet) gained the properties of cancer. [citation needed] The common adenomas of the colon (colorectal adenoma) are the tubular, tubulovillous, villous, and sessile serrated (SSA). [18]

    Fibroadenoma of the breast is a benign tumor composed of a biplastic proliferation of both stromal and epithelial components. [ 12 ] [ 13 ] This biplasia can be arranged in two growth patterns: pericanalicular (stromal proliferation around epithelial structures) and intracanalicular (stromal proliferation compressing the epithelial structures ...

    Three variants are known to exist, FAP and attenuated FAP (originally called hereditary flat adenoma syndrome [1]) are caused by APC gene defects on chromosome 5 while autosomal recessive FAP (or MUTYH-associated polyposis) is caused by defects in the MUTYH gene on chromosome 1. Of the three, FAP itself is the most severe and most common ...
