  schema:description "To find the sentinel lymph node, a radioactive tracer and often a blue dye are injected near the tumour. Severe allergic reactions to the blue dye are rare (about 2 in 1,000 in the largest pooled study) but can come late, so the team asks about allergies beforehand and watches you closely for at least an hour. Your urine may be blue for a day and the skin can stay blue-stained for a while."@en ;
