Which type of polyp has a thin stalk?
Pedunculated polyps are mushroom-like tissue growths that attach to the surface of the colon’s mucous membrane by a long, thin stalk.
Are polyps with stalks cancerous?
Not every sessile polyp will become cancerous. Only a small minority of all polyps become cancerous. That includes sessile polyps. However, sessile polyps are a greater cancer risk because they’re tricky to find and may be overlooked for years.
Can you pull out a polyp?
This type of surgery is known as a polypectomy and is often performed using an endoscope – a tube with a tiny camera that gives your doctor a detailed view inside your nose and sinuses. During this procedure, the polyps and any other problematic tissue can be precisely removed.

Does number of polyps matter?

Can a doctor tell if a polyp is cancerous by looking at it?
Adenoma polyps are the types of growths (along with other tissue abnormalities) that doctors are on the lookout for during colonoscopies. Although most adenoma polyps never become cancerous, it’s impossible to tell which ones will in the future just by sight.
