Why would anti-estrogen medication be prescribed for TNBC when it doesn't rely on estrogen?

You're absolutely right to question this. Triple-negative breast cancer (TNBC) doesn't have estrogen receptors, progesterone receptors, or HER2 receptors. This means anti-estrogen medications (hormone therapies) won't work for TNBC because there are no hormone receptors for these drugs to target.

TNBC is typically treated with:
- Chemotherapy (often the main treatment)
- Surgery to remove tumors
- Radiation therapy
- Immunotherapy drugs like pembrolizumab (Keytruda) if your cancer makes the PD-L1 protein
- PARP inhibitors like olaparib (Lynparza) if you have BRCA gene mutations
- Targeted therapies like sacituzumab govitecan-hziy (Trodelvy) for metastatic disease

If you've been prescribed an anti-estrogen medication, it's worth having a conversation with your oncologist to clarify why. There may be another reason related to your specific situation, or there could be a misunderstanding about your treatment plan. Your oncologist can explain the rationale behind each medication in your regimen.
