My father was diagnosed with Clarks Stage 4 melanoma last week. We are just starting the process and I have been reading a lot about it. I read somewhere that the clarks level of staging is not as widely used anymore because there a more accurate staging. When everyone talks about level 4, what kind of level are you refering to(clarks,etc)? I am so scared and my heart goes out to all of you dealing with horrible disease. Any advice or info people could offer would really be greatly appriciated. I have conviced him to go t Roswell Park Cancer Institue (thank god we close). I just don't know what questions to ask or what expect. Thank you and God Bless all of you.
