Understanding Aromatase Inhibitors: An Essential Course

Introduction to Aromatase Inhibitors

Aromatase inhibitors are a class of medications widely used in the treatment of hormone-sensitive breast cancer. They work by blocking the aromatase enzyme, which converts androgens into estrogens in the body. By reducing estrogen levels, these inhibitors can slow the growth of certain tumors that depend on estrogen for their development.
