3mm hypodense liver lesion in caudate lobe & two 3mm hypodense pancreatic head lesions on ct in setting of carcinoid workup. can these be tumors?

May or may not be: It takes time and follow up CT scans to see if these tumors are growing in size. if they are not tumors(cancer) it will remain unchanged in size over a period of 3-6 months. A biopsy may be required to confirm it in case these lesions are increasing in size(growing bigger). They are too small to do a biopsy now, need to be at least 1Cm or bigger.
