I agree with Angela. My first reaction after reading your message is
also that it does not sound cancerous to me. I have a mole similar
to the second one that you described and I've had it checked a couple
times just because it worries me. The Drs. that I have asked all say
it's nothing to worry about.
By all means, though, do get it looked at...better to be safe.
Big hugs,
Aimee
