How do I choose among systemic therapy options in breast cancer?
Short answer
Subtype, stage, genomic assays, and comorbidities guide systemic choices. Compare goals, duration, side effects, and whether therapy is neoadjuvant or adjuvant rather than focusing only on drug names.
Why patients ask this
Patients face dense information about chemo, endocrine therapy, targeted agents, and immunotherapy combinations.
Key factors to consider
- Receptor/HER2 status
- Stage and nodal involvement
- Genomic assay results when relevant
- Fertility and comorbidity constraints
- Side-effect priorities
Questions to ask your doctor
Bring these to your next visit to clarify the decision in front of you.
- What is the goal of systemic therapy in my sequence?
- Which options are equivalent, and which are clearly preferred?
- How will we monitor benefit and toxicity?
