Study may help explain sunlight's role in melanoma development

A strong link exists between lifetime exposure to ultraviolet light, particularly lifetime sunburns, and the development of melanoma ? the most lethal form of skin cancer. Now, for the first time, scientists have identified a specific molecular pathway within cells that becomes mutated by ultraviolet light exposure, thereby speeding up melanoma development.
