Hang in there, Victoria!
I have a mess on my arm, which I can remember first seeing in about 7th grade--after having it frozen off several times, it was finally diagnosed when I was nearly 30 as actinic keratosis (basal cell carcinoma). I have had it removed two times since then (I'm 43 now) . . . but it's back again. Sigh.
The great news is that it is tiny (about 1/8 x 1/4"), and although it is cancer of a kind, mine is really NOT DANGEROUS--just an ugly souvenir of too many sunburns as a kid at the cabin.
Don't panic, my dear. Many other less scary diagnoses are also possible, but even the "worst" is probably not so bad. <<hugs>>
