In the next year, nearly 120,000 new cases of melanoma will be diagnosed in the United States, more than half of which will be invasive disease.

Dr. Désirée Ratner, director of dermatologic surgery at Columbia University Medical Center, shares her expertise with host Dr. Mary Leuchars on strategies to recognize early development and initiate treatment of melanoma and nonmelanoma skin cancers.
