According to estimates from the American Cancer Society, melanoma, the most serious form of skin cancer, was responsible for an estimated 8,650 deaths in the United States in 2009. Of growing concern among dermatologists is the fact that melanoma is now the most common form of cancer for young adults 25-29 years old and the second most common cancer in adolescents and young adults 15-29 years old. Early diagnosis is the key to curing this potentially deadly disease, and diagnostic tools are playing a crucial role in aiding dermatologists to spot melanomas at earlier -- and more curable -- stages.
