The ABCDEs of Melanoma

What to look for in moles and beauty marks: 

Asymmetry – Growths in which one half doesn’t match the other half. 

Borders – Irregular borders with edges that are ragged, notched or blurred. 

Color – Pigmentation that’s not uniform; with shades of tan, brown and black present. Dashes of red, white and blue may add to the mottled appearance. 

Diameter – Size greater than six millimeters (about the size of a pencil eraser). Any mole growth should be of concern. 

Evolution – Changes in size, shape, color, or elevation, or any new symptom such as bleeding, itching or crusting.
