a "node" is a shortened form to mean lymph node. there are lymph nodes in many places of your body. like your neck under your arms groin and your mesenteric (near the intestines). lymph nodes "react" (enlarge or become inflamed) in response to inflammation and/or infection in their immediate neighborhood. colitis itself can cause reactive nodes and does not automatically mean cancer. of course inflammation can be caused by cancer too. a polyp is an inflammatory growth. and would by inside the intestine in your case. some polyps are cancer. some are pre-cancerous. but most are benign. these are questions that your doctor should be addressing with you since he/she is familiar with your case and can interpret your ct scan first-hand.
