Letrozole is a medication primarily used in the treatment of breast cancer, particularly in postmenopausal women. As an aromatase inhibitor, it works by reducing the amount of estrogen produced in the body, which can slow the growth of certain types of breast tumors that require estrogen to grow.

Effects of Letrozole

- Efficacy in Advanced Cases: Letrozole is effective in both early-stage and advanced-stage breast cancer cases, offering treatment options for a wide range of patients.
- Potential for Off-label Uses: Some research suggests Letrozole may be beneficial in other conditions such as infertility treatments, particularly in women with polycystic ovary syndrome (PCOS).
Possible Side Effects
While Letrozole has many positive effects, it is essential to be aware of potential side effects, which can include:
- Hot flashes
- Joint pain
- Fatigue
- Nausea
- Bone density loss
Patients should discuss these side effects with their healthcare provider to better understand their personal risk and management strategies.
