a substance capable of preventing full expression of the biological effects of an estrogen
a substance (for example, the drug tamoxifen) that blocks the effects of estrogen on tumors. Antiestrogens are used to treat breast cancers that depend on estrogen for growth.
A substance that blocks the activity of estrogens, the family of hormones that promote the development and maintenance of female sex characteristics. For example, tamoxifen (brand name: Nolvadex) is an antiestrogen.
a drug (e.g. tamoxifen) that blocks the effects of estrogen on the tumour
substance (i.e., tamoxifen) that blocks the effects of estrogen on tumors.
A hormonal therapy that blocks estrogen; these medications are used to treat breast cancers that depend on estrogen for growth.
Any agent or drug that blocks the effects of estrogen; these medications are used to treat breast cancers that depend on estrogen for growth.
A substance that blocks the effects of the hormone estrogen on tumors (for example, the drug tamoxifen). Antiestrogens are used to treat breast cancers that depend on estrogen for growth.
A substance that blocks the effects of estrogens (a family of hormones that helps develop and maintain female sex characteristics and the growth of long bones).
a substance that blocks the effects of estrogen on tumors. Antiestrogens are used to treat breast cancers that depend on estrogen for growth, i.e. Tamoxifin.
A substance or agent that can prevent the full expression of estrogen. In soy, weak estrogen-like isoflavones can take the place of estrogen and connect with receptors in estrogen-sensitive tissues, like breast tissue. By competing with estrogen for the limited number of estrogen receptors, the isoflavones prevent estrogen from binding to the receptors and, hence, may block proliferation of hormone-dependent cancers by interfering with the growth of estrogen-dependent tumors. The isoflavones, therefore, act as Antiestrogens.
