Answer would be Pancreatic Cancer.
Sir, May you Rest in Peace
Pancreas is an organ which lies in your stomach area or abdomen, on the left side, high above. It’s actually said to occupy the middle of the Epigastrium and Left Hypochrondium.( The abodmen is divided in 9 areas for surgeons to handle the situation). The Pancreas secretes enzymes which help to digest the food that you take in.
Risk Factors:
Smoking ( Virtually all the Cancer have this as a risk factor )

Its more common in the Western World , Men are twice likely to have this than women

Survival Rate :

5yr survival rate after surgery and chemoradiotherapy : In Early Diagnosed Cases
6-10 months for locally advanced Cancers
3-5 months if the Cancer has progressed beyond the Pancreas.
