Understanding Letrozole: What Is It?
Letrozole is a medication primarily used in the treatment of hormone receptor-positive breast cancer in postmenopausal women. This article will delve into its uses, mechanisms, and important considerations for patients.
What Is Letrozole?
Letrozole belongs to a class of drugs known as aromatase inhibitors. By inhibiting the aromatase enzyme, it reduces estrogen levels in the body, which can help slow or stop the growth of certain types of breast tumors that require estrogen to grow.
How Does Letrozole Work?
- Decreases estrogen production: Letrozole works by blocking the conversion of androgens into estrogens in adipose tissue.
- Reduces tumor growth: Lower estrogen levels can lead to a decrease in the proliferation of estrogen-sensitive tumors.
- Used in various stages: Letrozole may be used as part of adjuvant therapy following surgery or as a primary treatment for advanced disease.
Uses of Letrozole
The primary indications for letrozole include:
- Treatment of early-stage breast cancer after surgery.
- Adjuvant therapy to reduce the risk of cancer recurrence.
- Management of advanced breast cancer in postmenopausal women.
- Fertility treatment: Sometimes prescribed off-label to stimulate ovulation in women with infertility issues.
Potential Side Effects
Like any medication, letrozole may cause side effects, including:
- Hot flashes
- Joint pain
- Fatigue
- Nausea
- Bone density loss
