FORT MYERS, Fla.-- A new study suggests that young people who are exposed to ultraviolet radiation from lamps used for indoor tanning have a greater risk for developing basal cell carcinomas at a young age. Dr. Annette St. Pierre Mackoul joined Stephanie Susskind on WINK News This Morning to explain. A new study says 74 percent of high school students have a tanning salon within two miles of where they live. Dr. Mackoul says the ultraviolet rays from indoor tanning are ten to 15 times stronger than ultraviolet rays from the midday sun. As of January 2014, there were 450,000 non-melanoma skin cancer cases, and 10,000 melanoma cases. Melanoma cases are more serious and life threatening. Doctors say you always need to use at least an SPF 30 sunscreen when you're out in the sun.
