Apart from the added benefit of not looking like a lobster the next day, sunscreen shields us from powerful UV rays.

B - Is the border irregular? Even, smooth, circumscribed edges are a good sign for non-cancerous moles.
C – Is there a color differences within the mole? Non-cancerous moles are usually a single brown or tan while cancerous moles appear uneven color distribution of blue, black, brown or tan.
D – What is the diameter of the mole? Cancerous moles are usually bigger then the size of a pencil eraser.
