　　Melanoma is one of the only forms of cancer that is still on the rise and is the most common form of cancer in young **s. The incidence of melanoma in women under age 30 has increased more than 50 percent since 1980.
　　"When melanoma is diagnosed early, the prognosis is good. However, once it spreads, it is very difficult to treat. Melanomas and moles can appear similar on the skin and under the microscope making diagnosis of some melanomas difficult. That's why we wanted to determine whether a test for DNA methylation is feasible as a tool for diagnosis," added Nancy Thomas, MD, PhD, professor of dermatology and a member of UNC Lineberger Comprehensive Cancer Center.
　　Kathleen Conway Dorsey, Ph.D, added, "We are very excited because, with this study, we have shown that this type of testing is feasible and that it has the potential to reliably distinguish between melanoma and benign skin lesions. Devising a molecular test that could aid in the early specific diagnosis of melanoma could have significant benefit for patients." Conway is assistant research professor of epidemiology at UNC's Gillings School of Global Public Health and a member of UNC Lineberger Comprehensive Cancer Center.
