Hi Ellen,
Welcome to the site. I’m sorry to hear about your dad and that you had to find us all here, but I am glad that you have joined us as you will get tons of support and help from all of us. I came here in 2008 after my dad was diagnosed and it was the best thing that I could have done.
Please don’t worry about how the website works, just post away as much as you want! And if you have any questions at all then just ask and we will all try and help if we can. My dads CC was also inoperable and he had PDT as his treatment. Please let us know how your dads biopsy goes and what treatment his docs think he should have, and remember that we are all here for you.
My best wishes to you and your dad,
Gavin
