Hormonal agents are used to treat some cancers. An example is:
- A. thyroxine to treat thyroid cancer.
- B. ACTH to treat adrenal carcinoma.
- C. estrogen antagonists to treat breast cancer.
- D. glucagon to treat pancreatic carcinoma.

Estrogen antagonists can also be administered to prevent breast cancer in women who have a strong family history of the disease. Thyroxine is a natural thyroid hormone. It does not treat thyroid cancer. ACTH is an anterior pituitary hormone that stimulates the adrenal glands to release glucocorticoids; it does not treat adrenal cancer. Glucagon is a pancreatic alpha cell hormone that stimulates glycogenolysis and gluconeogenesis; it does not treat pancreatic cancer.
