Some cancers do seem to run in families such as breast and colorectal . Doctors advise you get tested sooner and more often if there is a family history of these types but I am not sure about pancreatic. Ask your Dr about your concerns
I don't think it is very likely, it may be likely if you are in the same environment, but if you are an adult and do not live or work or even spend time in the same environment, then you probably won't get it. Cancer is not genetic.
