Estrogen antagonists are used to treat estrogen hormone-dependent cancer, such as breast carcinomA. Androgen antagonists block testosterone stimulation of androgen-dependent cancers. An example of an androgen-dependent cancer would be:

Prostate cancer.Thyroid cancer.Renal carcinoma.neuroblastoma.

Explanation.

Prostate tissue is stimulated by androgens and suppressed by estrogens. Androgen antagonists will block testosterone stimulation of prostate carcinoma cells. The types of cancer in options 2-4 are not androgen dependent.
