It's great that you're exploring all your options! Yes, switching to tamoxifen after trying aromatase inhibitors (AIs) is something that can happen, especially when AIs aren't well tolerated.
While AIs are generally the first-choice hormonal therapy for postmenopausal women, tamoxifen is a valid alternative. It works differently — instead of stopping estrogen production, it blocks estrogen's effects in breast tissue. Some things worth knowing about tamoxifen at your stage:
- It can still help reduce the risk of breast cancer recurrence
- Common side effects include hot flashes, night sweats, fatigue, and mood changes
- Unlike AIs, it doesn't typically cause the muscle and joint pain that many people find difficult
- It does carry a small risk of blood clots, so your care team will want to monitor you
Many MyBCTeam members have navigated similar decisions about switching hormonal therapies.
The most important step is having an open conversation with your oncologist about your full treatment history so they can tailor the best plan for you. You deserve a treatment that works *and* feels manageable! 💛
