lumpectomy
LowFormal, Medical
Definition
Meaning
A surgical operation to remove a benign or malignant tumor from the breast while preserving most of the breast tissue.
More broadly, a surgical procedure involving the local excision of a small mass or lump from any tissue, though this usage is rare and 'lumpectomy' is overwhelmingly specific to breast surgery.
Linguistics
Semantic Notes
The term is almost exclusively used in medical contexts, particularly oncology. It is often contrasted with 'mastectomy' (full breast removal). The focus is on preservation and minimally invasive removal of a discrete lump.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'люмпэктомия' in general contexts, as it is a highly specialized medical term. In non-medical explanation, phrases like 'удаление опухоли (сохраняя грудь)' or 'органосохраняющая операция на груди' are clearer.
Common Mistakes
- Pronouncing it as 'lump-ectomy' (with a hard 'p' and full syllable) instead of the standard 'lum-pectomy'.
- Using it to refer to the removal of any lump anywhere on the body without medical context.
- Spelling as 'lumpectomy' (missing the 'e').

No, radiation therapy is very commonly recommended after a lumpectomy to eliminate any remaining microscopic cancer cells in the breast and reduce the risk of recurrence.
Yes, sometimes a lumpectomy is performed to remove a benign lump if it is large, painful, or causing concern, though the term 'excisional biopsy' is more common in that context.
