A high proportion of breast cancers are Estrogen Receptor Positive. This means they have a large number of estrogen receptors, indicating that estro....

HER2 is a gene that creates HER2 proteins or receptors. These receptors help control growth and repair of breast cells. An overexpression of HER2 protein causes out-of-control reproduction of breast cells. HER2-positive breast cancers are known to be more aggressive than HER2-negative breast canc....
