The HER2 protein helps control normal cell growth. Higher levels of the HER2 protein, or too many copies of the HER2 gene, can be produced by some types of cancer, including breast, ovarian, bladder, pancreas, and stomach cancer. This can cause cancer cells to grow faster and spread to other parts of the body. A human epidermal growth factor receptor 2 test may be performed to aid in treatment planning, which may include drugs that target the HER2 protein. It's a kind of tumor marker test.
