In brief: To slow growth
Most breast cancers are stimulated by estrogen and progesterone, the normal female sex hormones.
When deprived of these hormones, the tumors often die. Consequently, breast cancer tumors are tested to find out if they are sensitive to these hormones. If so, medicines to block these hormones are given as part of the cancer treatment for breast cancer.

They are used ONLY if the tumor expresses am estrogen/progersterone receptor, an assay done on the tumor when resected, in the path department. These drugs wither block or partially block the receptor, or undo the ability to producse estrogen, a driving force.

We can discern estrogen and Progesterone receptors on path speciments of breast ca. Only those that are er/pr+ will benefit from anti-estrogen drugs.
