question: Hi I had an accident and during the course of various tests a CAT Scan of my abdomen showed a 8 x 3 cm mass in my mesentery. The hospital brushed it off as a possible hematoma or benign tumor. My doctor sent me for a follow up CAT Scan at the 1 month  point last week. Still waiting on the results but the lab tech said the mass had gotten bigger. Are masses in the mesenteric area usually cancerous? Is it something that needs removed even if its benign?
