    Let's move on to Colon Polyp. With polyps, we begin with benign first. Benign meaning to say very low risk of going on to malignancy. Hyperplastic polyp just like we'd find in the stomach would be in fact benign. And you can have at times a Hamartomatous polyp. What is the definition of Hamartoma? Absolutely non–neoplastic, by definition. And I've mentioned this to you before, but with Peutz–Jegher polyp by definition even though it's a hamartoma, you will think of this as being a tumor marker. So even though this is non–neoplastic, your patient may then go on to develop breast cancer, colorectal cancer, maybe ovarian cancer if she's a female, so on and so forth. Peutz–Jegher. Inflammatory polyp, reaction to inflammation, especially common in Ulcerative colitis. So more or less your benign polyp but every once in a while you can always have the tendency of going on to malignancy. Let us now talk about Neoplastic polyps. We'll begin with the one that we, well, still will be adenomatous. However, there are two major types that you want to keep in mind. The tubular, so you're doing a colonoscopy. When you do a colonoscopy, now you find a finger–like projection, a tube, and you call this pedunculated or stacked, all the same thing. Tube, stacked, sitting on a pedestal, pedunculated, if that helps you. The chance of going on to colorectal cancer or malignancy extremely rare or decreased risk for tubular. Because if you're thinking about invasion, think of it this way, if you move down the tube, the neoplastic cells do, it could, it could, right? It has to invade through the submucosa mucosa and then that's a lot of invasion. Lower risk but it could. Whereas if you had a polyp that was flat, flat, meaning it...
