My dad scan results say prediculaire liver tissue mass in extended peri pancreatic cephalic and he needs to do biopsy is his pancreas cancer killer?

Biopsy Needed: I think most of us would understand your worry but would also caution you that until the tissue is actually biopsied and evaluated by a pathologist it would be unwise to predict the outcome or type of problem this could represent. I am sure your dad's doctor is going to recommend some test to determine specifically what this abnormal tissue is.
