If it is seborrheic keratosis, it is benign, exophytic (a lesion or growth that grows outward from the skin's surface), warty and lightly pigmented and can become more common as a person grows older. It is important that you go to your appointment and have your mole checked to verify that there are no other issues. Your mole should be biopsied if you can't see a dermatologist and/or the diagnosis is uncertain. It is always a good idea to watch your moles for changes as this should be a sign that you should see your doctor. There is a chart to help you identify your moles at http://www.skincancerguide.ca/tf/content.asp?z=817. Make sure you examine your scalp, back, elbows, underarms, legs – all those places that you don’t readily see. Use two mirrors, as this makes the examination somewhat easier. You are looking for changes in color, size, shape, edges. Also be conscious of a change in elevation and any sensations or surface changes. If any of these changes occur, they should be checked by a medical professional.
