Breast tumors are tested to see if they are estrogen receptor (ER) and/or progesterone receptor (PR) positive or negative. Hormone receptor tests are both prognostic and predictive. In general, tumors that are ER and/or PR are slightly slower growing and have a slightly better prognosis than tumors that aren’t. Hormone receptors also provide information about treatment options. If your tumor is ER and/or PR , then your cancer can be treated with a hormone therapy. For this reason, these tumors are also sometimes referred to as “hormone sensitive.” Hormone therapies slow or stop cancer's growth by changing the hormonal milieu. For early stage cancer, these treatments include tamoxifen and a class of drugs called aromatase inhibitors or AIs. dapoxetine 30 mg side effects Hormones are substances that function as chemical messengers in the body. They affect the actions of cells and tissues at various locations in the body, often reaching their targets through the bloodstream. The hormones estrogen and progesterone are produced by the ovaries in premenopausal women and by some other tissues, including fat and skin, in both premenopausal and postmenopausal women and men. Estrogen promotes the development and maintenance of female sex characteristics and the growth of long bones. Progesterone plays a role in the menstrual cycle and pregnancy. Estrogen and progesterone also promote the growth of some breast cancers, which are called hormone-sensitive (or hormone-dependent) breast cancers. Hormone-sensitive breast cancer cells contain proteins called hormone receptors that become activated when hormones bind to them. Tamoxifen uses in males Nolvadex-D Tab 20mg.

While an aromatase inhibitor is the first hormonal therapy medicine choice for postmenopausal women, tamoxifen is the first choice for premenopausal women and is still a good choice for postmenopausal women who can't take an aromatase inhibitor. Selective estrogen receptor modulators, called SERMs for short, block the effects of estrogen in the breast tissue. SERMs work by sitting in the estrogen receptors in breast cells. If a SERM is in the estrogen receptor, there is no room for estrogen and it can't attach to the cell. If estrogen isn't attached to a breast cell, the cell doesn't receive estrogen's signals to grow and multiply. Cells in other tissues in the body, such as bones and the uterus, also have estrogen receptors. But each estrogen receptor has a slightly different structure, depending on the kind of cell it is in. So breast cell estrogen receptors are different from bone cell estrogen receptors and both of those estrogen receptors are different from uterine estrogen receptors.
