How should I compare lumpectomy and mastectomy?
Short answer
For many early breast cancers, lumpectomy plus radiation and mastectomy can offer similar cancer control when candidates are appropriately selected. The decision often hinges on tumor extent, genetics, reconstruction preferences, and radiation willingness.
Why patients ask this
Patients hear that both can be oncologically sound and need help weighing personal priorities.
Key factors to consider
- Tumor size relative to breast size
- Multicentric disease
- Genetic risk and future risk reduction goals
- Radiation feasibility and preference
- Reconstruction timing and body-image priorities
Questions to ask your doctor
Bring these to your next visit to clarify the decision in front of you.
- Am I an appropriate candidate for breast-conserving surgery?
- How would genetic results change surgery recommendations?
- What does recovery look like for each option?
