They are pretty tiny (1 mm or less) brown color, larger ones are slightly raised.
I checked the melanoma websites, his are not large enough to qualify, however couple of them have irregular shape (but they are very very tiny compared to the pictures on skin cancer sites)
I have several moles too, that are irregular size, I think I'll have to see a dermatologist myself.
Speaking of skin cancer, are there natural ways to heal it?
