Treatment possibilities include selective estrogen-receptor response modulators (SERMs), aromatase inhibitors, estrogen-receptor downregulators (ERDs) and luteinizing hormone-releasing hormone agents (LHRHs). HER2 negative cancers will not respond to treatment with drugs that target HER2, such as trastuzumab (Herceptin) and lapatinib (Tykerb).
What is hormonal therapy For HER2-negative advanced breast cancer?
Hormonal therapy is often the first treatment doctors use for women with HER2-negative advanced breast cancer that's "hormone receptor positive." Some 50%-70% of breast cancers are hormone receptor positive. That means your hormones, like estrogen or progesterone, help the cancer grow. Hormonal or endocrine therapies help to block this process.
What are the different types of hormone therapy for breast cancer?
There are several types of hormone therapy for breast cancer. Most types of hormone therapy either lower estrogen levels in the body or stop estrogen from helping breast cancer cells grow. These drugs work by stopping estrogen from fueling breast cancer cells to grow.

What is the link between estrogen and breast cancer?
Studies have also shown that a woman's risk of breast cancer is related to the estrogen and progesterone made by her ovaries (known as endogenous estrogen and progesterone). Being exposed for a long time and/or to high levels of these hormones has been linked to an increased risk of breast cancer.

What is HER2 gene?
In some pathology reports, HER2 is referred to as HER2/neu or ERBB2 (Erb-B2 receptor tyrosine kinase 2) . Hormone receptors are identified as estrogen (ER) and progesterone (PR). The HER2 gene creates HER2 proteins, or receptors. These receptors help control the growth and repair of breast cells.
