1. What is letrozole cinfa and what is it used for
What is letrozole cinfa and how does it work
This medicine 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. Letrozole cinfa reduces the amount of estrogen by blocking an enzyme (aromatase) involved in estrogen production, and thus can 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 letrozole cinfa used for
Letrozole 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 5 years of treatment with tamoxifen. Letrozole is also used to prevent the breast tumor from spreading to other parts of the body in patients with advanced breast cancer.
If you have any questions about how this medicine works or why you have been prescribed it, ask your doctor.
