Cancer is a pervasive problem in America.
According to the American Cancer Society, over 8 million Americans currently have a history of cancer. Cancer causes more deaths in the US in children ages 1 - 14 than any other disease. One of the most important challenges and opportunities facing public health professionals is to emphasize cancer prevention directed toward preventable cancer causes. Smoking is the leading cause of cancer and dietary factors are the second most common cause. Studies have shown a third preventable cause is exposure to excessive amounts of intense sunlight.
