Contents of the pack
What is Letrozol SUNand how does it work
Letrozol SUN contains the active substance letrozole. It belongs to a group of medicines called aromatase inhibitors. It is a hormonal (or "endocrine") treatment for breast cancer. The growth of breast cancer is often stimulated by estrogens, which are female sex hormones. Letrozol SUN reduces the amount of estrogen by blocking an enzyme ("aromatase") involved in estrogen production and can therefore block the growth of breast cancers that need estrogens to grow. As a result, tumor cells grow more slowly or stop growing and/or spreading to other parts of the body.
What is Letrozol SUN used for
Letrozol SUN is used to treat breast cancer in women who have gone through the menopause, i.e., the cessation of menstrual periods.
It is used to prevent breast cancer from coming back. It can be used as the first treatment before breast cancer surgery, if surgery is not immediately possible, or it can be used as the first treatment after breast cancer surgery, or after five years of treatment with tamoxifen. Letrozol SUN is also used to prevent the breast tumor from spreading to other parts of the body in patients with advanced breast cancer.
