no we do not know a clinical level yet . my dad was going to a dermatoligist who is not very "talkative". he has an appt. wed. with a surgeon and will hopefully find out more. can you be a clinical level 1 or 2 if it's that deep? we really don't know much of anything yet and that really scares me, the waiting is horrible and i know it's only the begining. thank you for your quick reply, i can use any support i can get to stay strong for my dad.
