Colonic neoplasm is when new tissue grows in the colon, or large intestine. It can grow into polyps, which begin as benign (not cancerous) growths, but can sometimes develop into cancer over time. Many neoplasms and polyps are first discovered during a routine colonoscopy.

Symptoms

You may not have any symptoms if it is benign or precancerous. If cancer develops, you may have unexplained fatigue, change in bowel habits, abdominal discomfort such as gas or cramps, blood in stool, or rectal bleeding.

Treatment

A colonoscopy can find neoplasms and polyps before they become cancerous. When they are found during the procedure, the gastroenterologist will remove them. This prevents them from turning into cancer. They will also send them to a lab to test them. The results will determine how closely you have to follow up with another colonoscopy.
