My husband has pancreatic cancer. We are told he was one of the lucky few who could have surgery. He had a surgery known as "whipple", the surgery was extensive. He also had chemo and radiation.
I am sure that your father is not putting you on. We were informed that chemo is ineffective with pancreatic cancer too. The reason my husband had chemo and radiation was because the pathology showed additional cancer cells.
From our experience, this has proven to be quite painful for my husband.
As a mother of three sons, I speak from my heart. Please forgive any past hurts and get to know your dad before it is too late. All our research indicates that life expectancy is not very long once diagnoised. So spend some quality time with him because I seriously doubt that anyone would say they have something like this if it were not so.
May god bless you and your dad as you go on this journey together.

I'm so sorry to hear about your father. My husband died 2 years ago with pancreatic cancer. He was also given a a 99% liklihood of dying. However, his oncologist told him to go ahead and try to chemo, even though he had a 1 % chance of survival. My husband opted for the treatment, but it had no efftect whatsoever. He was given 8 months to live, and he lived almost 8 months.

Pancreatic cancer is almost always fatal unless detected early, and is usually not responsive to chemotherapy.

I hope you can spend some time with your father and be a support to him during this.

My prayers are with you.
