I know what you're talking about here. I used to tell everyone that my legs had more Marks than a German Bank but I can't say that now they switched to Euros
I had a malignant melanoma removed then went to see a dermatologist every 3 months for 3 years. I very often came home minus another mole & plus several stitches
Personally I'd think a monthly check up is a wee bit excessive.
Saraly, best wishes for tomorrow. You'll be absolutely fine I'm sure, so try not to worry.
