A fusion happens when part of the ROS1 gene joins with part of another gene and forms an abnormal \u201chybrid\u201d gene. This change can act like an \u201con switch\u201d that helps some cancers grow. ROS1 fusion testing is most commonly used in solid tumors such as lung cancer, especially when targeted therapy is being considered."}
