2024年10月31日 · HER2 positive. Breast cancer cells that make a lot of extra HER2 protein are called HER2 positive. Targeted therapy treatments with medicine that hurts cells making too much HER2 can help control this kind of breast cancer. HER2 low. Breast cancer is called HER2 low if some of the cancer cells show signs of making extra HER2.

In about 20% of breast cancers, the cells make too much of a protein known as HER2. These cancers tend to be aggressive and fast-growing. For women with HER2-positive breast cancers, the...

Breast cancer cells with higher than normal levels of HER2 are called HER2-positive. These cancers tend to grow and spread faster than breast cancers that are HER2-negative, but are much more likely to respond to treatment with drugs that target the HER2 protein .

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.

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-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 often cure this cancer if it’s caught early on.

Patients with HER2 + and estrogen receptor-positive (ER +) cancer are additionally treated with long-term hormone therapy. This study examined the metastatic pattern and prognosis of both ER + /HER2 + and ER - /HER2 + breast cancer.

2025年2月20日 · Up to 21% of invasive breast cancers in the U.S. have mixed hormone receptor status. In other words, the tumors are classified as either estrogen receptor positive and progesterone receptor negative (ER+/PR-) or estrogen receptor negative and progesterone receptor positive (ER-/PR+).

Estrogen receptor-positive breast cancer (ER+) happens when high levels of estrogen in breast cancer cells help cancer grow and spread. Finding out if cancerous cells have estrogen or progesterone receptors helps healthcare providers plan breast cancer treatment. Providers often treat ER+ breast cancer with surgery and hormone therapy.
