"Activity of key proteins separate cancer from benign mole, scientists say
TUESDAY, March 31 (HealthDay news) -- Identifying the differences between melanoma skin cancer and a harmless mole can still be a tough call for even trained specialists. But scientists say differences in levels of certain genetic markers may help distinguish between the two lesions.
Melanoma is the deadliest form of skin cancer. Standard microscopic examinations of tissue biopsies can be ambiguous, so using this new technique along with standard practice could help clarify difficult-to-diagnosis cases, according to researchers from the University of California, San Francisco.
They found that both the level and the pattern of activity of five proteins can distinguish benign moles from melanoma. Testing the diagnostic technique on 693 previously diagnosed tissue samples, they found that it correctly diagnosed 91 percent of melanomas and 95 percent of benign moles. The technique also correctly diagnosed 75 percent of the most difficult cases that had previously been misdiagnosed."
