[Letrozole]

Letrozole reduces the levels of the female sex hormone oestrogen in the body. Oestrogen promotes the growth of certain breast cancers. These breast cancers are referred to as hormone-sensitive or hormone receptor positive. Letrozole can halt or reduce the progression of several tumors. Letrozole is a medicine that is often used to treat breast cancer in women. It works by reducing estrogen levels in the body, which can help prevent or stop the growth of cancerous cells. Estrogen is a hormone that promotes the growth of certain forms of breast cancer. Letrozole works by inhibiting an enzyme called aromatase, which is responsible for estrogen production in the body. Letrozole, by inhibiting this enzyme, can limit the amount of estrogen in the body, so preventing cancer cells from developing and spreading. Letrozole is an important medicine that can help treat breast cancer by reducing the body's estrogen levels.
