Published: March, 2014

Q. Should I worry if new colon polyps appear near where previous ones have been removed?

Some polyps never cause any symptoms. Others cause symptoms, such as bleeding, but never turn cancerous.

Adenomatous comes from adenoma, the medical term for any tumor that grows from the epithelium, a layer of glandular cells that line the inside of an organ.
