It's killed my uncle, my grandmother, my cousin. My aunt has it and has been given two years to live, if she is lucky. My mother had it and has just past the five years mark, so is hopefully OK, but she is checked every month.
I told my doctor and he had a cursory glance at my moles (I am like a Dalmatian) and just said "Oh they look fine to me." and seemed very uninterested about my family history.
I've read up a bit about it on the internet, and if you are ginger (which most of my relatives are) then you are at higher risk of familial melanoma. I'm dark, so fingers crossed, I'll be OK. But given that my uncle, grandmother and cousin all live in the same area and were under the same hospital, and have same unusual surname, I wonder why no-one has picked this up to have a look at more closely?
