It looks like you're asking about HER2, which is an important marker in endometrial cancer.

HER2 (Human Epidermal Growth Factor Receptor 2) is a protein that can appear on the surface of cancer cells. When endometrial cancer is HER2-positive, it means the cancer cells have too much of this protein, which can make the cancer grow faster.

Knowing your HER2 status matters because it opens up specific treatment options. If your endometrial cancer is HER2-positive, targeted therapies like trastuzumab (Herceptin) or Enhertu can be used to specifically attack those cancer cells.

Your healthcare team will test for HER2 status along with other markers to help create the most effective treatment plan for your specific situation.
