ABCD Rules for Skin Cancer

As a follow-up to the post written on melanomas of the feet and toes-We’d now like to discuss the criteria to use when making the decision on whether or not to visit a practitioner based upon the appearance of a lesion. Dermatologists and healthcare providers of all kinds like to refer to the “ABCD(E) rule” when evaluating the appearance of a mole, freckle, or recently found lesion of the skin in regards to its malignancy potential. Here is the breakdown of the rule:

• A stands for Asymmetry. A lesion that isn’t symmetrical due to uneven division of skin cells
• Irregular Borders that seem to be ragged, or unusual looking
• Color variations that seem to be inhomogeneous & abnormal
• A large Diameter of the lesion (>6mm) -Yes, use a ruler and measure!
• Lastly, abnormal or uneven Elevations should not be present, & should cause concern!

These 5 criterion should be used in the evaluation of any, and every kind of lesion found on the skin to ensure malignancy isn’t a possibility! The feet are sometimes neglected as part of the evaluative process of the skin performed by dermatologists, so be sure to closely monitor and check all surfaces of your feet when you perform routine footcare on yourself. If you do happen to notice irregularities don’t hesitate to contact a podiatrist. Lesions that are malignant are comprised of rapidly dividing cancer cells and time is of the essence!
