Hi Dina,
i was diagnosed with mucosal melanoma in my nose and later sinus. I had discussions with oncologists in Singapore who were all not melanoma specialists. I put the info on my blog for you to read. Hope there is information you find useful. I studied and learned a lot through q&a with specialists
i underwent cleanup surgery 5 weeks ago and will travel to Japan tomorrow for proton beaming. This is better than normal radiation as it's more accurate with no side effects.
wishing you well as I am in the middle of the struggle find the right treatment.
Cor
