Hello Chloe and welcome
Diagnosis is a shock, even when you half expect it. To hear those awful words fill you with dread.
As Julie says, there are many on here that are like your dad.
We are always directing people to this site's Toolkit a set of leaflets/booklets which deal with diagnosis and treatments.
Go back to the home page, then Publications . You can either download them or ask for hard copies.
Don't despair, ask away ANY questions you may have, I guarantee somebody will know what you are talking about.
If nothing else, we are here for virtual hugs and support.
Best Wishes
Sandra
