How Letrozole Works
Letrozole works through a specific mechanism that focuses on reducing estrogen production. The main effects include:

- Slowing Tumor Growth: Lower estrogen levels can slow the growth of tumors that have estrogen receptors.
- Post-Treatment Benefits: Letrozole is also beneficial in post-treatment care as it can help prevent recurrence in patients who have completed primary breast cancer treatment.
Potential Side Effects
Like any medication, Letrozole comes with potential side effects. Some of the most commonly reported include:
- Hot flashes
- Joint pain
- Fatigue
- Headaches
- Nausea
