A gene called HER2 produces proteins in the breast. When HER2 cells in the breast tissue instruct your body to generate too many copies of the cells, this is where HER2 positive breast cancer occurs. Tumors grow as a result of this. HER2 positive cancers frequently advance and metastasize quickly. These excess copies of the cells often spread to other body parts. This indicates that the cancer has spread.

How Enhertu acts:

This results in cell death, which can cause the tumor to lessen.
