[|Human|] 1 1/2 yrs ago my brother, age 81 had a biopsy done on a mass found on his pancreas...it was benign.  He just  had a CT Scan done and now this mass has grown to 11cm , almost 1/2 inch larger than before.  The doctor will be doing a biopsy next week.  I asked him can it be removed and he said no because of its size and because of its location.Is 11cm considered very large?  Although it was benign before but because it has continued to grow do you feel this time it could be cancer?  Thank you...Teriann
[|AI|]  Hello, Thanks for the query to Chat Doctor. Forum. The size of pancreas is usually not more than 15 cm. Head, body and tail are the main parts of pancreas. Usually the benign carcinoma rarely develops in head , if present may be malignant so get a surgery for this part, however final decision will be taken by a surgeon. In my opinion consult one more surgeon and get his opinion before biopsy (if biopsy excisional will be the best). Good luck.
