Urgent referral to dermatologist - really worried

Hi everyone, 

I’ve just found this forum and I was hoping for some helpful, reassuring words. 

I am 25 years old and have had a suspicious mole on my shoulder change quite significantly over the last 4 months. Fast forward to this week and my GP examined it under a dermatoscope after it had changed again. These pictures were then sent to the dermatologist and within 24 hours my GP called me to say the dermatologist wanted to see me under an urgent, 2 week referral.

This has made me really worried as the dermatologist has already seen the pictures from the dermatoscope and, from what I understand, it is these pictures which have warranted an urgent referral. 

Can anyone who has experienced this process before please let me know what to expect at my appointment? It’s in 6 days. 

Thankyou,

Sophie xx
