Can breast cancer be caused by stress?
Yes, the women exposed to stress are at a higher risk of developing breast cancer than the non-exposed.
Is HER2 a hormone receptor?
Hormone Receptors and Human Epidermal Growth Factor (HER2) Expression in Fine-Needle Aspirates from Metastatic Breast Carcinoma – Role in Patient Management.
What does HER2/neu positive mean?
If your cancer is HER2/neu positive, you may respond to a specific drug that targets HER2/neu receptors. Results for IHC: A score of 0 or +1 means your tumor is HER2 negative. A score of +2 means the results are unclear and FISH testing should be done. A score of +3 means the tumor is HER2 positive.
What is the significance of her hormone receptor status?
Why is knowing hormone receptor status important? Knowing the hormone receptor status of your cancer helps doctors decide how to treat it. If your cancer has one or both of these hormone receptors, hormone therapy drugs can be used to either lower estrogen levels or stop estrogen from acting on breast cancer cells.
How does stress affect cancer cells?
Stress hormones can inhibit a process called anoikis, which kills diseased cells and prevents them from spreading, Sood says. Chronic stress also increases the production of certain growth factors that increase your blood supply. This can speed the development of cancerous tumors, he adds.
What does it mean to be hormone receptor positive?
(HOR-mone reh-SEP-ter PAH-zih-tiv) Describes cells that have a group of proteins that bind to a specific hormone. For example, some breast cancer cells have receptors for the hormones estrogen or progesterone. These cells are hormone receptor positive and they need estrogen or progesterone to grow.
What does HER2 mean?
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.
What is Neu mean?

Is HER2/neu the same as HER2?
The proteins they make can also be tested. The HER2 gene makes HER2 proteins (also sometimes referred to as HER2/neu proteins). HER2 proteins are receptors on breast cells.
What does HER2 status mean?
HER2 stands for human epidermal growth factor receptor 2. It was discovered in the 1980s. HER2 proteins are found on the surface of breast cells. They’re involved in normal cell growth but can become “overexpressed.” This means that a person’s levels of the protein are higher than normal.
Is it better to be HER2-negative or positive?
HER2-positive cancer tends to be poorer in terms of prognosis than HER2-negative cancer because: It grows faster. It is more likely to spread to the lymph nodes fast. It is at least two times more likely to return than HER2-negative tumors.
What does HER2/neu positive breast cancer mean?
Again, this means that the cancer cells may receive signals from progesterone that could promote their growth. Similarly, HER2/neu positive (HER2/neu + ) status of the breast carcinoma mean that HER2/neu gene is making too many HER2/neu proteins. HER2/neu proteins are receptors on breast cells.
What is the relationship between HER2/neu expression and prognosis?
HER2/neu expression is associated with poor prognosis (high risk of recurrence [ROR]); however, it also predicts that a patient will more likely benefit from anthracycline and taxane-based chemotherapies and therapies that target HER2/neu (trastuzumab), but not to endocrine-based therapies. [1], [2] ER and PR are nuclear receptors.
What is the role of hormone receptor studies in breast cancer?
Hormone receptor studies such as ER, PR, and HER2/neu are routinely done in breast carcinoma. It not only helps in the prognosis of the tumor but also helps in deciding its treatment.
What are estrogen receptor and progesterone receptor?
Estrogen receptor (ER) and progesterone receptor (PR) are hormone receptors found on breast cells that pick up hormone signals resulting in cell growth.
