Was your father suffering from pancreatic adenocarcinoma?
Did he have a chronic inflammation of the pancreas?

My mother died from pancreatic cancer and any doctor I have ever talked to says it is a cancer that does not usually run in families.

It depends what was the cause of pancreatic cancer.
New studies have shown that pancreatic cancer can run in families.
First, there is a chronic pancreatitis (inflammation of the pancreas starting at an early age) that is hereditary (runs in families) and can be a risk factor for pancreatic cancer.
Also, people with two or more cases of pancreatic cancer in their family (on the same side), but no recognised gene faults, may have 'familial pancreatic cancer syndrome'. This means they have a higher risk of getting pancreatic cancer than the general population.

any treatment for this cancer

My mom has pancreatic cancer in the head of her pancreas, a year before that she was diagnosed with diabetes. Both my great grandmothers had the same thing. I pray to God that it is not genetic. Pancreatic cancer is incurable and chemotherapy will only slow it down. My mom was given 6 months to live and she is still here after 13 months and is only now in a lot of pain, which breaks my heart to see.
