Welcome to the site. Sorry you had to find us all and I'm sorry to hear about your Dad. Glad that you have joined us all here as I know you'll get a load of support and help from everyone. Our Gerry is from Ireland as well. He had a whipple and hopefully he will be along soon to share his experiences and knowledge of Ireland and where he was, diagnosed, treated, hospitals etc. Was your Dad seen by doctors in a hospital in Dublin or elsewhere?
Thanks for letting us know what he has been through so far. Please do not give up hope. You have done the right thing in seeking further information about all of this as the more info you have the better you will be informed and that will help you so much. There is so much info here on the site both in the toolbars at the top of the page and also from what the members have shared regarding theres or their loved ones experiences. Using the search forum function at the top of the page will throw up tons of discussions on so many issues.
And also, please feel free to ask any questions that you have and we'll do what we can to help in answering them. We are here for you and we know what you are going through. Please stay in touch with us all and let us know how things go for your dad and what the Onc says as well.
My best wishes to you and your dad,
