September 12, 2010 Certainly, if you have moles, you should be careful about paying attention to them and knowing when there are danger signs. You should get your moles looked at once a year to make sure that you aren’t in any danger. Certainly, if you see these irregular mole types, you should seek assistance from an expert like Dr. Lawrence Jaeger of Larchmont, New York. Look for asymmetric moles, moles with undefined edges, moles which are raised higher than the surrounding skin and have a rough texture, and moles that measure more than ¼ of an inch. In addition, if any of your moles change shape or color, you should definitely consult a doctor.
