White spots are not a typical sign of cancer. Itching is usually a sign of irritation, not cancer. Yes, a dermatologist can tell whether a mole is benign or not just by looking. From your description, I very much doubt that the mole under your jaw needs to be removed, but when you see the doctor you will learn whether it needs to be removed and if so how. I don't know how you can get in earlier, but I don't see any rush or reason for you to worry, based on what you've told me.
Take care.
