The fact that it is on the
lip is problematic. Many good dermatologists
who would otherwise simply freeze
off suspicious spots will not do that with the lip, because it is disfiguring to do so. I have a mole below my lower lip but right on the line (it's called the "vermillion line") of the lip, and my regular derm won't touch it. Anyway, if your husband really has cancer, please get him in to see whatever dermatologist will treat him.
