Have new ones checkd: Although changes in our skin are normal as we age, if u notice new changes that r concerning have them looked at by your regular doctor. Most benign skin changes are easy to identify by looking at them. Skin cancer identification is defined by the a, b, c's. A- asymmetric shape. B- borders that are irregular, c-color (multiple colors are concerning) there are some more features but these r basics.

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.
