In brief: "cousin-drugs"

Tamoxifen ("anti-estrogen") and aromatase inhibitors (ai) are both used for treating breast cancers that are estrogen-receptor +.
Ai's are only suitable after menopause but may be slightly more effective; furthermore, they are not associated with any increased risk of uterine cancer like tamoxifen.

In brief: Pharmacology

Anti-estrogens block the receptors to which estrogen attaches on the cell.
Anti-aromatases prevent estrogen from being made in the body.
