It is important to understand the difference between existing spots, freckles and moles and potentially cancerous moles. A common mole usually has an even color of pink, tan or brown.
The Skin Cancer Foundation recommends that everyone practice monthly head-to-toe self-examinations of your skin, so that you can find any new or changing lesions that might be cancerous or precancerous. If you notice anything new or different, it's time to go see your dermatologist.
Board certified dermatologist and Associate Professor of Dermatology at the Mayo Clinic College of Medicine, Dr. James A. Yiannias, MD, explains the warning signs of (and factors surrounding) cancerous moles and what to look for during self-examinations.
