Fulvestrant is known as a hormonal breast cancer treatment. It is used to treat advanced breast cancer and metastatic breast cancer. Advanced breast cancer is cancer which has progressed despite treatment, and metastatic breast cancer is cancer which has spread into other parts of the body.
Many breast cancers need the female hormone oestrogen to grow. The cells of these cancers have tiny areas called receptors on their surface, which oestrogen can attach to. They are called 'hormone receptor-positive' cancers. Fulvestrant works by blocking the receptors and this prevents oestrogen from reaching the cancer cells. This slows the growth of the cancer.

Fulvestrant is used to treat breast cancer that has spread to other areas of the body in women who have gone through "the change of life" (menopause). It is used in patients who have not responded well to other medications (e.g., tamoxifen). Breast cancer cells need the hormone estrogen in order to grow. Fulvestrant works by blocking the effect of estrogen, slowing tumor cell growth.
How Fulvestrant Works:
Many breast cancers are stimulated to grow by the female sex hormones oestrogen and progesterone. These breast cancers are called hormone sensitive or hormone receptor positive. Drugs that block the effects of these hormones can slow or stop the growth of the breast cancer cells. Fulvestrant stops oestrogen getting to the cancer cells by blocking oestrogen receptors and reducing the number of receptors the cancer cells have.
