The radioactive dye travels to the sentinel node which can be detected by shade improve and/or by gamma probe (Hunt et al.
Grossing of the specimen really should move forward only after a decision is created on how the specimen must be processed; this is based around the specimen together with the medical record supplied within the specimen ask for variety.
