The thing about dermatology is it's very visual. So patients are going to know if they're getting better. They're going to know if they're not getting better. Even though the prevalence of melanoma is definitely increased, patients are very aware of it, and they are coming in just for body screenings as a routine. Just like going to get a physical, they're coming to have their skin looked at - which is great, because so many things are caught early, and you can really make the patient's life a lot better.
