Hello Sdaqqett,
I am assuming you mean the cancer is located at the head of the Pancreas. This is the area where the Common Bile Duct meets with the Pancreatic Duct at the Duodenum.
I don't know if you have a question or you are telling us of these horrible cancer your husband has. I am sorry to hear this.
It is well known that teavelling in Southeast Asia for a long period of time and drinking their water or eating their fresh fish or just eating any of their food that has been washed with their water you have a very good chance of getting Bile Duct Cancer. There is parasites in the water.
This is a very slow cancer...it can take 15 years to surface, but when it does it is usually in a stage III or IV status.
Again, I am very sorry to hear of your husband cancer.
My wife was diagnosed in 2003 and battled this cancer until it took her life on December 2, 2010.
