Estrogen dependent breast cancer would give the best prognosis for woman. Most of the estrogen in women’s bodies is made by the ovaries. Estrogen makes hormone-receptor-positive breast cancers grow. So reducing the amount of estrogen or blocking its action can reduce the risk of early-stage hormone-receptor-positive breast cancers coming back (recurring) after surgery. Hormonal therapy medicines can also be used to help shrink or slow the growth of advanced-stage or metastatic hormone-receptor-positive breast cancers.
It’s important to know that hormonal therapy IS NOT hormone replacement therapy (HRT). HRT isn’t used to treat breast cancer. HRT is taken by some women to treat troublesome menopausal side effects such as hot flashes and mood swings. HRT is used to raise estrogen levels that drop after menopause.
HRT contains estrogen and can contain progesterone and other hormones. Hormonal therapy is exactly the opposite — it blocks or lowers estrogen levels in the body.
