Anastrozol, a medication commonly used in the treatment of hormone receptor-positive breast cancer in postmenopausal women, functions by inhibiting aromatase, an enzyme involved in estrogen production. By lowering estrogen levels, Anastrozol helps to slow or stop the growth of certain types of breast tumors that require estrogen to grow. Understanding its effects, benefits, and potential side effects is crucial for individuals considering this treatment.

  2. Joint Pain: Some individuals may experience musculoskeletal pain or stiffness.
