A polyp is a abnormal growth within the colon. It is a reason to why we do colonoscopies in order to remove these polyps so that they don't grow and become cancerous in the future. Approximately, I would say 60 to 70% of people that have a colonoscopy will end up having some amount of polyps in their colon and those are all removed. The type of polyps,, the growth and size of the polyp and the amount of polyps that a patient can have vary. That's dependent on diet, that's dependent on genetics. And every patient is different and they're usually asymptomatic, which means patients usually don't have symptoms when they have polyps and that's why we have to do the screening procedures.
