Moles and other birthmarks are benign pigmented spots or patches of skin that range in color from tan, brown and black (moles) to red, pink or purple (vascular lesions, such as strawberry hemangiomas or port wine stains). Though most birthmarks are harmless, they may develop into cancer. Moles exhibiting any of the following warning signs should be examined by a professional immediately:
- Larger than six millimeters
- Itches or bleeds
- Rapidly changes in color, size or shape
- Has multiple colors
- Is located where it can’t be easily monitored, such as on the scalp
Depending on their depth, location and color, as well as the patient’s skin type, age and other factors, treatment for benign but unattractive birthmarks may take the form of laser or pulsed light therapy, microdermabrasion or surgical excision.
