What is HER2 and what does it mean? HER2 is a protein that helps breast cancer cells grow quickly. Breast cancer cells with higher than normal levels of HER2 are called HER2-positive.

2024年4月9日 · HER2-positive breast cancer is a breast cancer that tests positive for a protein called human epidermal growth factor receptor 2 (HER2). 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.

HER2 is named as such due to structural similarities with human epidermal growth factor receptor 1, or HER1. The Neu alias of HER2 derives its name from the parent glioblastoma cell line - a type of neural tumor found in rodents.

2023年8月28日 · HER2-positive (HER2+) breast cancer affects some people who have invasive breast cancer. This is a fast-growing cancer that can quickly spread from your breast to other areas of your body. Healthcare providers can treat and …

2022年8月22日 · HER2 positive breast cancer has the same symptoms as other types of breast cancer. Patients often find a lump, or a routine mammogram spots one. Inflammatory breast cancer can also be HER2 positive, so patients may notice a rash or other breast changes.

HER2 (human epidermal growth factor receptor 2) is a protein. Some breast cancer cells have a higher than normal level of HER2 on their surface, which helps them to grow. This is known as HER2-positive breast cancer. Less than 1 in 5 invasive breast cancers are HER2-positive.

2025年3月3日 · You will likely hear your care team talk about testing for your cancer’s HER2 status. HER2 stands for human epithelial growth factor receptor 2, a protein that cancer cells may overproduce. Determining whether your cancer is HER2 positive will help guide important treatment decisions moving forward.

2024年7月24日 · Traditional chemotherapy, radiation and surgery still play an important role in the treatment of HER2-positive cancers. These treatments often are used along with newer treatments that target HER2-positive cancer in slightly different ways. There are three main types of HER2-targeted therapies.

2022年9月20日 · Learn the difference between HER2-negative and HER2-positive breast cancer, how doctors test for the protein and how results affect treatment options.

HER2 (human epidermal growth factor receptor 2) is a gene that can play a role in the development of breast cancer.
