Breast cancer her2 status about 15% to 20% of breast tumors have higher levels of a protein known as her2 You may hear the term “biomarker” to describe her2 Ask your cancer care team about your her2 status and what it means for you.

This protein promotes the growth of cancer cells
In about 1 of every 5 breast cancers, the cancer cells have extra copies of the gene that makes the her2 protein.
The fact that the cancer is positive for her2 will affect your treatment and survival Experts consider the her2+ breast cancer to be more aggressive than some other breast cancers. Debu tripathy, m.d., explains what makes her2 positive breast cancer more aggressive than other cancer types, plus how it’s diagnosed and treated. The her2 (human epidermal growth factor receptor 2) gene makes her2 proteins (also called her2/neu proteins)
Her2 proteins are receptors on breast cells Her2 receptors help control how a breast cell grows, divides, and repairs itself. Abstract human epidermal growth factor receptor 2 (her2) protein overexpression and/or her2 gene amplification is found in about 20% of invasive breast cancers It is a sole predictive marker for treatment benefits from her2 targeted therapy and thus, her2 testing is a routine practice for newly diagnosed breast cancer in pathology.
Her2 status her2 (human epidermal growth factor receptor 2) is a protein that appears on the surface of some breast cancer cells
It may also be called her2/neu or erbb2 The her2 protein is an important part of the pathway for cell growth and survival All breast cancers are tested for her2 status
