Introduction
Breast cancer can feel overwhelming. Femara (letrozole) offers hope. It’s a prescription drug that fights breast cancer in postmenopausal women. Curious? Let’s explore what it’s all about.
What Is Femara?
Femara, also called letrozole, is an aromatase inhibitor. It blocks an enzyme called aromatase. This enzyme turns androgens into estrogen. By stopping it, Femara cuts estrogen levels. Lower estrogen slows down some breast cancers.
- Who Uses It? Postmenopausal women with breast cancer.
- How It Comes: 2.5 mg tablets.
- Does It Cure Cancer? No, it manages it.
Doctors often prescribe Femara after surgery or radiation. It’s part of hormone therapy.
How Does Femara Work?
Some breast cancers need estrogen to grow. Femara steps in to stop that. Here’s the simple version:
- The Issue: Aromatase makes estrogen from androgens.
- The Solution: Femara blocks aromatase.
- The Result: Less estrogen slows cancer growth.
Imagine Femara as a gatekeeper. It keeps estrogen away from cancer cells.
Benefits of Femara
Femara isn’t a miracle cure. But it brings big benefits. Check these out:
- Lowers Recurrence: Reduces the odds of cancer returning.
- Steps Up: Works when other treatments fail.
- Outshines Tamoxifen: Often performs better than tamoxifen.
A study called the BIG 1-98 trial showed Femara cuts recurrence risk by 19% compared to tamoxifen. That’s a game-changer for many.
How to Take Femara
Taking Femara is easy. Your doctor sets the plan. Here’s what to know:
- Dose: One 2.5 mg tablet each day.
- Timing: With food or without—it’s your choice.
- Missed a Dose? Take it when you recall. Skip it if the next dose is soon.
Follow your doctor’s advice. Don’t quit without asking them first.
