Human: My doctor says that I have a uterine polyp, and I'd like to find out more about them. Assistant: 
Uterine polyps are small growths in the uterus. They can be benign (noncancerous) or malignant (cancerous). Polyps are usually found during a pelvic exam, but they may also be detected by ultrasound. If your doctor thinks you have a polyp, he or she will likely perform a biopsy to determine whether it is cancerous.
