Estrogen positive refers to cells, often in Breast cancer, that have receptors for the hormone estrogen. This means that the growth of these cancer cells can be stimulated by estrogen. Treatments for estrogen-positive cancers may include hormone therapies that block estrogen's effects or lower its levels in the body to slow down or stop cancer growth. Identifying estrogen positivity is crucial for determining the most effective treatment plan.

What causes estrogen positive breast cancer to develop in individuals?
Estrogen positive breast cancer develops when there is an overabundance of estrogen in the body, which can stimulate the growth of cancer cells in the breast tissue. This type of breast cancer is often fueled by estrogen receptors on the cancer cells, making them more sensitive to the hormone.
What roles does estrogen play in the in the feedback mechanism?
Gonadotropin-releasing hormone (GnRH) is a neurohormone secreted by the preoptic nuclei of the hypothalamus. This hormone causes leuteinizing hormone to be released by the anterior pituitary. LH works its way through the bloodstream to the ovaries, which produce estrogen. Estrogen has a feedback loop with both the hypothalamus and the anterior pituitary. Whether the mechanism is positive or negative depends. In ovulation, this mechanism is positive, so high estrogen levels will induce even higher LH levels.
How does tamoxifen work?

What hormone causes chadwicks sign?

So, estrogen is the hormone responsible for a positive Chadwick's sign, however bloodflow is the reason it becomes blue.
Can HRT contribute to neoplastic changes in estrogen-sensitive aging tissue?

What effects does oestrogen have on the production of fsh?
Estrogen induces a biphasic feedback on the gonadotropin releasing. In the first phase (it is discussed whether the phases are separated by time or by estrogen levels) it induces an negative feedback on both FSH and LH. The inhibition of FSH is more evident in this case. In the second phase the feedback is positive. In contrary the positive feedback is much more evident in the LH level.
