What are the symptoms of malignant melanoma?

Varies: Many melanomas are without symptoms. Some are itchy, irritated, or may bleed. They have often changed shape, size or color, but these changes are usually asymptomatic. If the melanoma has spread, there are multiple other symptoms that could possibly occur.

ABCD's: Remember your abcd's when thinking of melanoma. Look for moles with asymmetry boarders that are irregular color differences within the same mole diameter greater than 6mm also any new mole or old that starts to itch, bleed or ulcerate should be of concern. Another rule is the ugly duckling rule. Which refers to a mole that looks distantly different from the others on your body.
