Hormones are substances that function as chemical messengers in the body.

They affect the actions of cells and tissues at various locations in the body, often reaching their targets through the bloodstream.

Breast tumors that lack progesterone receptors are called progesterone receptor negative (PR or Pg R negative).

Hormone therapy for breast cancer should not be confused with menopausal hormone therapy (MHT)—treatment with estrogen alone or in combination with progesterone to help relieve symptoms of menopause.

Progesterone plays a role in the menstrual cycle and pregnancy.

Tumors that are hormone insensitive do not have hormone receptors and do not respond to hormone therapy.Hormone-sensitive breast cancer cells contain proteins called hormone receptors that become activated when hormones bind to them.The activated receptors cause changes in the expression of specific genes, which can stimulate cell growth.Examples of ovarian suppression drugs that have been approved by the U. Food and Drug Administration (FDA) are goserelin (Zoladex®) and leuprolide (Lupron®).Blocking estrogen production: Drugs called aromatase inhibitors are used to block the activity of an enzyme called aromatase, which the body uses to make estrogen in the ovaries and in other tissues.
