Neoplasia is best defined as which of the following?

• A. Normal tissue development
• B. Autonomous uncoordinated cell growth
• C. Programmed cell death
• D. Reactive inflammation

Answer: (B)

Neoplasia describes growth driven by genetic changes that makes cells proliferate autonomously and without normal coordination with surrounding tissues. This means the cells expand on their own, ignoring the usual regulatory signals and feedback that normally control growth. It’s not normal development, which is regulated and organized; it’s not programmed cell death, which is a controlled way to remove cells; and it’s not reactive inflammation, which is an immune response. So the defining feature is autonomous, uncoordinated cell growth, which can form benign or malignant tumors.
