I forgot to tell you that I asked the GP what does a worrying possibly mole or wart look like, as I had no idea, and she said anything that changes in colour, and looks mottled, bleed or itched and had got to about 1cm in size.
Dont take this as read, but this is what I was told by the helpful Doctor, so if you have any worries about such things go and get it checked out. I am well relieved
She said that GP's are happy to look at any moles, and actively encouraged people to come in and have them checked if they were worried.
