Anti-Estrogens

An antiestrogen is a pharmaceutical agent that interferes with the biological actions of estrogen. Estrogen is a steroid hormone vital for the development and regulation of the female reproductive system and secondary sex characteristics. However, in certain conditions, such as hormone-receptor-positive breast cancer, estrogen can fuel disease progression. Understanding what is antiestrogen involves recognizing its role in mitigating these harmful effects by either blocking estrogen’s access to its receptors or reducing the body’s overall estrogen levels.
