Breast cancer<unk>  is used for the treatment of hormone receptor positive metastatic breast cancer or locally advanced unresectable disease in postmenopausal women; it is given by injection. A 2017 Cochrane review found it is as safe and effective as first line or second line endocrine therapy. It is also used to treat ER-positive, HER2-negative advanced or metastatic breast cancer in combination with palbociclib in women with disease progression after first-line endocrine therapy. Due to the medication's having a chemical structure similar to that of estrogen, it can interact with immunoassays for blood estradiol concentrations and show falsely elevated results. This can improperly lead to discontinuing the treatment. Early puberty<unk>  has been used in the treatment of peripheral precocious puberty in girls with McCune–Albright syndrome. Available forms<unk>  is provided in a castor oil solution also containing alcohol, benzyl alcohol, and benzyl benzoate. It is supplied at a concentration of 250 mg/5 mL.
