Trozet

What Trozet (Letrozole) is used for

Letrozole is a hormone (endocrine) tablet for breast cancer. It belongs to a group of medicines called aromatase inhibitors. After the menopause, the body still makes a little oestrogen using an enzyme called aromatase. Letrozole blocks this enzyme, so there is less oestrogen, and breast cancers that need oestrogen to grow are slowed or stopped. It is a prescription medicine that is started and checked by a breast cancer specialist team. Fertility specialists sometimes use it in a different way to help women release an egg.

• Hormone-sensitive (hormone receptor positive) breast cancer, mainly in women who have been through the menopause
• Lowering the chance of breast cancer coming back after surgery, radiotherapy or chemotherapy
• Shrinking a breast cancer before surgery, or treating it when surgery is not possible
• Breast cancer that has spread (advanced breast cancer)
• Lowering the chance of getting breast cancer in some women at high risk who have been through the menopause
• Sometimes breast cancer in men, or in women who have not reached the menopause, when a specialist advises it
