The world’s first genetic sequencing of precancerous lung lesions could pave the way for very early detection and new treatments report a new study led by UCL researchers. Before lung cancer develops, precancerous lesions are found in the airway, but only half of these will actually become lung cancer, while others will disappear or remain benign without becoming harmful. Under the microscope, the lesions look the same, making it difficult to know which lesions to treat. In a study, published…
