pancreatic cancer is often not even detected until the final stages -- often with only a few months to live.

Final stages include back pain, extreme weight loss or gain, sugars either high or low and a few other things.

Normally the back pain is due to tumor lodging themselves into the skin of the back. It also spread elsewhere - but is known for hitting the liver. Jaundice may follow, but it's normally the attacks on the liver that kill you.
