WebAug 11, 2024 · Some breast cancers produce too much of the protein HER2 because of a change in a gene called HER2/neu. Doctors use the FISH test to measure the amount of HER2/neu gene in each cancer cell. If the FISH test comes back strongly positive for HER2, it is much more likely that a drug called trastuzumab (Herceptin) will work.
