Awaiting diagnosis - Melanoma

I’m new here and I’m wondering if anyone can help. 

Basically for about 2 years, I’ve had a weird mole that I saw my previous GP about but he said he wasn’t worried about it so I was sent away. Since then it’s been growing and spreading and I can feel something niggling, sort of itching but not itching in that area, it just doesn’t feel right. On Monday I saw my new GP and she immediately referred me to a Dermatologist so I’m currently awaiting an appointment for that. 

I am very concerned about the outcome of course, and I’m trying not to think of the worst but it is hard not to. 

My question is, I’ve got hundreds of moles, they are everywhere and to me, lots of them have different colours in them and they are raised etc. Will the dermatologist only be able to look at the mole I’ve been referred for or will I be able to ask about the others too? 

Any advice on the process would be much appreciated- thanks!
