A colorectal polyp is a abnormal growth occurring within the lining of the colon or rectum.[1] Symptoms may vary from none, to blood in the stool, changes in bowel movements, or abdominal pain.[1] Bleeding is generally minor and non-visible in the stool.[2] Untreated, complications may include colorectal cancer.[1]
The cause may include inflammatory bowel disease or a number of genetic conditions such as familial adenomatous polyposis and Peutz-Jeghers syndrome, though most arise spontaneously.[2][3][4] Risk factors include alcohol, high fat diet, and smoking.[4] They may be benign, precancerous, or cancerous.[3] They can also be divided into adenomatous (65%) and nonadenomatous.[3][4] Diagnosis is generally by colonoscopy.[1]
A diet high in fruits and vegetables may decrease the risk.[4] Treatment involves removal.[1] However about a third of people will develop further polyps.[1] Aspirin may decrease this risk.[1] Colorectral polyps affect about 25% of adults in the US.[1] They are more common in males than females and become more common with age.[5]
