The present invention is directed to a method of treating estrogen responsive breast cancer in an individual comprising administering to an individual a therapeutically effective estradiol inhibiting amount of interferon gamma (IFN-γ) and / for a tumor necrosis factor (TNF) antagonist and / or an interleukin-1 (IL-1) antagonists. The invention is based upon the surprising discovery that IFN-γ and / or a tumor necrosis factor (TNF) antagonist and / or an interleukin-1 (IL-1) antagonists inhibit estradiol production in human adipocytes. This discovery is not only important because it allows for the treatment and / or prevention of estrogen dependent breast cancer using IFN-γ, TNF antagonists or IL-1 antagonist each alone or in combination, but also because IFN-γ and / or TNF antagonists and / or IL-1 antagonists can be used in conjunction with standard anti-estrogen therapy, e.g., tamoxifen and / or aromatase inhibitor, to result in lower estrogen levels than seen with standard anti-estrogen therapy alone. Moreover, the ability to lower estrogen levels by means of the present invention, when combined with standard anti-estrogen therapy, provides an important therapeutic option in that it allows the dose of the anti-estrogen to be reduced, reducing the likelihood of side effects and complications commonly seen with anti-estrogen therapy.
