Staging breast cancer is the initial step to help physicians determine the most appropriate course of treatment. As of 2016, guidelines incorporated biologic factors, such as tumor grade, cellular proliferation rate, estrogen and progesterone receptor expression, human epidermal growth factor 2 (HER2) expression, and gene expression profiling into the staging system.
Anastrozole is used in the treatment and prevention of breast cancer in women. [7] The Arimidex, Tamoxifen, Alone or in Combination (ATAC) trial was of localized breast cancer and women received either anastrozole, the selective estrogen receptor modulator tamoxifen, or both for five years, followed by five years of follow-up.

Tamoxifen selectively blocks the effect of estrogen in breast tissue but acts as an estrogen agonist in the uterus and in bone. [2] Research shows that women on tamoxifen for at least 5 years out of surgery are less likely to have recurrent breast cancer, including new breast cancer in the other breast, and death at 15 years.

The use of high-dose estrogen therapy in breast cancer has mostly been superseded by antiestrogen therapy due to the improved safety profile of the latter. [17] High-dose estrogen therapy was the standard of care for the palliative treatment of breast cancer in women up to the late 1970s or early 1980s. [18
Additionally, the pelvic musculature and connective tissues are estrogen sensitive and respond to changes in estrogen level. [2] Estrogen deficiency, which can occur during menopause, can affect the production of collagen that is needed to build connective tissue that makes up ligaments and fascia, which can contribute to uterine prolapse.

Baywatch star Nicole Eggert shared a health update regarding her year-long (and counting) journey with breast cancer. In December 2023, Eggert was told she had stage 2 of a rare, slow-growing form ...
Exemestane is an oral steroidal aromatase inhibitor that is used in ER-positive breast cancer in addition to surgery and/or radiation in post-menopausal women. The main source of estrogen is the ovaries in premenopausal women, while in post-menopausal women most of the body's estrogen is produced via the conversion of androgens into estrogen by ...
The study, which looked at data from 2004 to 2021, found that advanced breast cancer rates have risen among women of all ages, with the sharpest increases in young women aged 20 to 39, and women ...
