Stage 4 melanoma cancer

Hi all, My Dad has recently been diagnosed with stage 4 melanoma cancer (BRAF negative) with mets in his brain, lungs and liver. My family and I are devastated to say the very least. He has started radio and immunotherapy, and has an excellent team looking after him, but the stats are still quite sobering. I’m an ICU nurse for context so I have a decent understanding of it all. I guess I’m just wondering whether anyone has any positive stories they can please share after being in a similar position? Thank you x
