Symptoms of Melanoma   

The first sign of skin cancer is a mole that has changed its shape or its color.  In nodular melanoma the first indication is a lump on the surface of the skin.  During later stages of the disease the mole may ulcerate, bleed or itch.  Melanoma lesions usually appear with irregular borders and varying shades of colors.  Their initial diameter is usually the size of a pencil eraser and they will grow and spread out as time goes on.
