Is it common to find polyps during a colonoscopy?

A colonoscopy is considered positive if the doctor finds any polyps or abnormal tissue in the colon. Most polyps aren't cancerous, but some can be precancerous. Polyps removed during colonoscopy are sent to a laboratory for analysis to determine whether they are cancerous, precancerous or noncancerous.

Also question is, how long does it take for a polyp to turn into cancer?

Since it is hard to determine the exact nature of a polyp, polyps found during colonoscopy are removed and sent to the lab for a microscopic analysis. How long does it take a colon polyp to grow into a cancer? Current theories propose it will take about 10 years for a small adenoma to transform into a cancer.

Is it common to have polyps?

Polyps are very common in adults, who have an increased chance of acquiring them, especially as we get older. While quite rare in 20-year-olds, it's estimated that the average 60-year-old without special risk factors for polyps has a 25 percent chance of having a polyp. We don't know what causes polyps.

Can removing polyps cause cancer?

Some colon polyps are benign, which means they are not cancerous, but some can be precancerous or cancerous. The relationship of certain polyps to cancer is well established. Polyps can usually be removed during colonoscopy.
