hyperplasia
C2Scientific/Medical/Formal
Definition
Meaning
An abnormal increase in the number of cells in an organ or tissue, causing enlargement.
A proliferation of cells that remains under normal physiological control, as opposed to neoplasia (cancer), where growth is uncontrolled.
Linguistics
Semantic Notes
Used primarily in medicine, biology, and pathology. Implies an increase in cell number, not cell size (which is hypertrophy). Often refers to a benign, reactive process.

Examples
By Part of Speech
verb
British English
- The glandular tissue began to hyperplase, leading to a diagnosis of benign hyperplasia.
- The pathologist noted that the cells were hyperplasing in response to the stimulus.
American English
- The tissue hyperplased in response to hormonal stimulation.
- Chronic irritation can cause the epithelium to hyperplase.
adverb
British English
- The cells grew hyperplastically.
- The tissue reacted hyperplastically to the stimulus.
American English
- The gland enlarged hyperplastically.
- The response was hyperplastically excessive.
adjective
British English
- The hyperplastic changes in the endometrium were clearly visible.
- He presented with a hyperplastic thyroid gland.
American English
- The biopsy revealed hyperplastic polyps.
- The condition is characterized by hyperplastic growth.
Examples
By CEFR Level
- The doctor explained that the patient's enlarged prostate was due to a benign condition called hyperplasia.
- Some skin conditions involve hyperplasia, making the skin thicker.
- Endometrial hyperplasia is a potential precursor to carcinoma and requires careful monitoring.

Mnemonic
Imagine a HYPER market (HYPER-) where the number of stalls is constantly increasing (-PLASIA = formation). HYPER-PLASIA = excessive formation of cells.
Conceptual Metaphor
N/A (Highly technical term).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with "гипертрофия" (hypertrophy), which is an increase in cell size, not number.
- The Russian direct equivalent "гиперплазия" is a perfect cognate with identical meaning.
Common Mistakes
- Confusing hyperplasia with hypertrophy or neoplasia.
- Using it in non-medical contexts.
- Mispronouncing the '-plasia' part as /pleɪʃə/ vs. /pleɪzɪə/ in UK English.

FAQ
Frequently Asked Questions
No. Hyperplasia is an increase in the number of normal cells. While it can sometimes be a precursor, it is not cancer itself, which is called neoplasia and involves uncontrolled, abnormal cell growth.
Often, yes. If the stimulus causing the hyperplasia is removed (e.g., a hormone imbalance is corrected), the hyperplastic tissue may regress or return to normal.
Benign Prostatic Hyperplasia (BPH) is a very common condition in older men, where the prostate gland enlarges due to an increase in cell number.
It is typically diagnosed through a combination of clinical examination, imaging (like ultrasound), and definitively by histopathological examination of a tissue biopsy under a microscope.
