Lot 35 lbs since July. Severe back pain. In 2015 mass in pancreas was 3.0cm now it is 3.6cm. Pancreatic head is at 4mm. Have done MRI, Ct, X-ray, colonoscopy, upper go. What's a rough estimate of this being cancer?? Never mind I can't pay this. I have already accumulated 15,000 in medical bills since January 1, 2017. Sorry for the inconvenience. Take care.
