Skin cancer is the most commonly diagnosed cancer in the United States, and most cases are preventable. Despite efforts to address skin cancer risk factors, such as inadequate sun protection and intentional tanning behaviours, skin cancer rates, including rates of melanoma, have continued to increase in the United States and worldwide. The goal of this book is to increase skin cancer awareness and to call for actions to reduce its risk. It outlines steps we can all take -- as individuals, parents, educators, employers, policy makers, health care professionals, and communities -- to reverse this alarming trend.
