polyposis
Meaning of polyposis: Polyposis is the development of numerous polyps, growths projecting from a mucous membrane, most often described within the colon.
Definition of polyposis
Polyposis is a condition marked by the development of numerous polyps, small growths that project from the surface of a mucous membrane. While polyps can form on various mucous membranes throughout the body, the term polyposis is most often used to describe multiple polyps forming within the colon and rectum.
The number of polyps involved distinguishes polyposis from having just one or a few isolated polyps, a common and often incidental finding on its own. Polyposis can occur sporadically or as part of an inherited condition, in which case numerous polyps may develop from an early age and carry an increased risk of the polyps eventually becoming cancerous.
Because a large number of polyps increases the overall chance that at least one will develop concerning cellular changes over time, polyposis is generally monitored more closely than the presence of a single, isolated polyp.
Used in a sentence
Colonoscopy revealed extensive polyposis throughout the colon.
Good to know
Polyposis describes the presence of numerous polyps rather than a single diagnosis in itself, and its significance depends heavily on whether the underlying cause is sporadic or an inherited condition.
