Be Smart About Skin
Some skin disorders are merely a nuisance—others can be debilitating or even deadly
Psoriasis is the most common inflammatory skin disease, and skin cancer is the most common type of cancer. To learn more about these diseases, we talked with Kenneth Gordon, MD, a board-certified dermatologist at Northwestern Lake Forest Hospital. Dr. Gordon is also a Professor of Dermatology at Northwestern University Feinberg School of Medicine, which serves as a leadership center for two research studies on new psoriasis medications.
According to Dr. Gordon: "Whether you have a spot that concerns you or symptoms like itching and redness, it’s always best to get an opinion. In many cases we’ll tell you it’s nothing to worry about. But don’t lose sleep over it—get the answers and, if needed, the right treatment."
Find out the basic facts that adults should know about risks to their skin and long-term health in this Q&A with Dr. Gordon.
