nephroblastoma
Very LowTechnical / Medical
Definition
Meaning
A malignant tumor of the kidney, typically occurring in young children.
A specific type of embryonal tumor that arises from immature kidney cells (nephrogenic blastema). It is the most common renal malignancy of childhood, with the peak incidence around ages 3-4.
Linguistics
Semantic Notes
This term is almost exclusively used in medical contexts, particularly in oncology, pathology, and pediatrics. It is synonymous with Wilms' tumor, though 'nephroblastoma' is the formal pathological name, while 'Wilms' tumor' is common in clinical practice.

Examples
By CEFR Level
- The doctor said the child had a tumor in the kidney.

- The histopathological examination confirmed the diagnosis of a favourable histology nephroblastoma.
- Treatment protocols for nephroblastoma often involve a combination of surgery and chemotherapy.
Learning
Memory Aids
Mnemonic
Think: 'NEPHRO' (relating to the kidney, like in nephrology) + 'BLAST' (immature cell) + 'OMA' (tumor). A 'blastoma' is a tumor of blasts (early cells). So, a kidney tumor made of early kidney cells.
Conceptual Metaphor
Often conceptualized as an 'invader' or 'uncontrolled growth' within the developing organ.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- The term is a direct internationalism: 'нефробластома'. No false friends exist.
Common Mistakes
- Mispronouncing as 'nephro-blast-oh-ma' with incorrect stress. The primary stress is on 'blast' (/blæˈst/).
- Confusing it with other 'blastomas' (e.g., neuroblastoma, which is in the nervous system).
- Misspelling as 'nephroblastomia' or 'nephroblastomaa'.

FAQ
Frequently Asked Questions
No. Nephroblastoma is a distinct, embryonal tumor almost exclusively seen in children. Adult kidney cancer is typically renal cell carcinoma, a different disease.
Yes, with modern multimodal therapy including surgery, chemotherapy, and sometimes radiotherapy, the overall survival rate for nephroblastoma is very high, often over 90% for localized disease.
In medical terminology, 'blast' refers to an immature or precursor cell. A 'blastoma' is a tumor arising from such cells.
It most commonly affects children between 2 and 5 years old. Certain genetic conditions, like WAGR syndrome or Beckwith-Wiedemann syndrome, increase the risk.
