My Flashcards

Definition

Meaning

A (usually benign) tumor of the pancreas that produces excessive amounts of insulin.

In medical contexts, it refers specifically to an insulin-secreting neuroendocrine tumor arising from the beta cells of the pancreatic islets, leading to hypoglycemia (low blood sugar).

Linguistics

Semantic Notes

The term is a compound of 'insulin' and the suffix '-oma' (denoting a tumor). It is a highly specific term with no non-technical meanings.

By CEFR Level

B1

Learning

Memory Aids

Mnemonic

Think: INSULIN + OMA (tumor) = a tumor that makes too much INSULIN.

Conceptual Metaphor

None applicable; it is a literal, technical term.

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Do not translate as 'инсулиновая опухоль' (calque). The standard medical term is 'инсулинома'.

Common Mistakes

  • Mispronouncing it as 'insulin-oma' with equal stress. Correct stress is on the third syllable: in-su-li-NO-ma.
  • Using it as a general term for diabetes-related issues.

FAQ

Frequently Asked Questions

Most insulinomas (about 90%) are benign (non-cancerous). A small percentage can be malignant.

Symptoms are caused by low blood sugar (hypoglycemia) and can include confusion, dizziness, sweating, weakness, palpitations, and, in severe cases, seizures or loss of consciousness.

The primary treatment is surgical removal. For inoperable cases, medications to control blood sugar or other therapies may be used.

No, it is a very rare condition, with an incidence of approximately 1-4 cases per million people per year.
