I have a 2 cm mass on the pancreas,as seen on MRI scan, PET scan shows uptake in the lungs and pancreas and adrenals , I have had two biopsies via EUS which are both negative , having another one on Monday 

the drs think the lung nodules look metastatic , so the scans show a bleak picture but the biopsies have been negative so far .

Anyone else experiencing this?
