  schema:description "To find the first lymph node a breast cancer drains to, UK surgeons inject a radioactive tracer and a blue dye. The blue dye is one of the causes of severe allergic reactions under anaesthesia and stains the skin. Pooled studies suggest a green fluorescent dye finds the node as well as the tracer and better than the two together, and that the blue dye does not lower the rate of missed cancer."@en ;
