COLUMBIA, Mo. – The fight against skin cancer just got a new weapon. For years, melanoma researchers have studied samples that were considered uniform in size and color, making them easier to examine by more conventional means. But melanomas don’t always come in the same shape and hue; often, melanomas are irregular and dark, making them difficult to investigate. Now, researchers at the University of Missouri have devised a new tool to detect and analyze single melanoma cells that are more representative of the skin cancers developed by most patients. The study, recently reported in Analyst published by the Royal Society of Chemistry, outlines the new techniques that could lead to better and faster diagnoses for the life-threatening disease.
