Melanoma is the riskiest, most lethal skin cancer and it's completely preventable. Dr. Sancy Leachman, the chair of dermatology at the Oregon Health and Science University, talks with Dr. Josh Sharfstein about Oregon's "War on Melanoma," an all-fronts effort to educate people on early identification, diagnosis, and prevention of melanoma. They also discuss the role of tattoo parlors in this campaign.
