Definition
- Noun:
- An abnormal new mass of tissue that serves no purpose: A neoplasm is a growth of new, abnormal tissue, often forming a lump or tumor. This growth is not part of the body's normal structure or function and can be benign (non-cancerous) or malignant (cancerous).
Usage
- The term "neoplasm" is a formal, medical term used by healthcare professionals. It is a neutral term that describes the abnormal growth itself, without specifying whether it is cancerous. Further tests (like a biopsy) are needed to determine if a neoplasm is benign or malignant.
Examples
- Noun:
- The biopsy confirmed the presence of a neoplasm in the lung.
- Not every neoplasm is cancerous; many are benign and harmless.
- Early detection of a neoplasm can significantly improve treatment outcomes.
