We know that a tan today means permanent sun damage tomorrow. Skin cancer is the most common type of cancer. Getting too much sun can lead to skin cancer. Today one in five adults develops skin cancer. It accounts for about one-third of all reported malignancies in the U.S. Malignant melanoma, the deadliest form of skin cancer, is beginning to occur at a much higher rate in women under 40.
Sun damage is cumulative.
It continues to add up over a lifetime. They result in premature aging and contribute to skin cancer formation. These are short wavelengths, and are believed to be the primary rays causing sunburns, and ultimately skin cancer. The Ozone Layer protects us by absorbing UVC rays. But as the ozone thins, we will be exposed to more UVC rays, which will possibly contribute to skin cancers and eye damage.
