@jodes1984: I understand, the GP likely suspects this is the case based on how it looks (perhaps like a crater or non-healing scar that has been growing rapidly, also as explained here: https://www.mayoclinic.org/diseases-conditions/squamous-cell-carcinoma/symptoms-causes/syc-20352480) so it was wise of them to refer you to the dermatologist. Even in the US, getting in with a dermatologist within 2 weeks is not all that long of a wait although it can seem interminable when you have this type of worry on your mind.

Quite honestly, I've had so many BCCs and SCCs, I cannot recall for sure how each one presented; even my melanoma appeared differently from typical ones you'd see in pictures as it was what is referred to as "amelanotyic" -lacking dark pigment - so my cases were probably different from yours. I got less and less concerned with each BCC and SCC as I'd become used to routine screening and more rapid identification and treatment which were mostly Mohs procedures. The melanoma did catch me by surprise and did cause stress prior to undergoing a wide local excission to remove it. Even in ensuing years and interventions that have followed as a result, I have successfully managed my condition. You're one step ahead of the game already knowing you have your appointment scheduled. When is the actual date for that so I can keep you in mind for you to follow up?
