D10-D36: Benign neoplasms

D12: Benign neoplasm of colon, rectum, anus and anal canal

Benign neoplasms of the colon, rectum, anus, and anal canal are noncancerous growths that form in the lining of the digestive tract. These are abnormal growths, but they do not spread or infiltrate the surrounding tissues like malignant (cancerous) tumors do. The exact cause of these growths is unknown, but they can result from abnormal cell growth or mutations. Symptoms can vary widely depending on the size and location of the neoplasm, but often include bloody stools, a change in bowel habits, abdominal pain, and discomfort. Some people may not experience any symptoms at all. The progression of these conditions can be slow and they do not typically affect the patient's overall life expectancy. The digestive system, specifically the parts of the large intestine, are affected by these conditions.
