benign tumour
Definition
Noun: A benign tumour is a mass of cells, or tumor, that grows in the body but is not cancerous. It does not invade nearby tissues or spread to other parts of the body (metastasize). These growths are often slow-growing and, while they may cause problems due to their size or location, they are generally not life-threatening.
Usage
The term is used in medical contexts to describe and classify non-cancerous growths, distinguishing them from malignant (cancerous) tumors. - It is typically modified by the specific type of tissue or cell from which it arises (e.g., a benign brain tumour, a benign skin tumour). - It is often discussed in contrast to a malignant tumour.
Examples
- The biopsy results showed it was a benign tumour, which was a great relief to the patient.
- Although the benign tumour in her breast was not dangerous, the doctor recommended removing it.
- Not all lumps are cancerous; many are benign tumours.
Advanced Usage
- "Benign" vs. "Malignant": This is the fundamental dichotomy in tumor pathology. A benign tumour remains localized, while a malignant one is invasive and metastatic.
- Clinical Significance: A benign tumour can still be clinically significant if it presses on a vital organ, nerve, or blood vessel, causing pain or dysfunction.
