HORMONAL THERAPY FOR CANCER?

Some breast cancer cells may be sensitive to the female hormone estrogen through the hormone receptors they contain.

Some breast cancer cells may be sensitive to the female hormone estrogen through the hormone receptors they contain. In other words, estrogen can cause these cancer cells to grow and multiply. The goal of hormone therapy is to prevent cancer development by eliminating the effects of estrogen in cancer types that contain estrogen receptors and are sensitive to this hormone. Current medications for this purpose are taken orally for long periods (three to five years).
