BIRTHMARKS
A red or purplish patch on the skin is the result, as mentioned in an earlier chapter, of an embryological accident in which one or more embryonic cells slipped out of place in the early days of skin formation. These accidental markings may occur on the face, the scalp, or on any other portion of the body, and they should be let alone, unless they show a tendency to grow, when it may prove best to give them proper surgical attention.
A mole is also a birthmark, and if found upon the neck or shoulders where it is likely to disfigure, it may be removed by the high-frequency spark, or by surgery, in the same way as warts. Never tamper with moles. Leave them alone or turn them over to the surgeon.
