Analyze the question stem
The question asks to identify which of the listed procedures involves the freezing of tissue.
Evaluate the word roots
Using the Medical Word Roots concept, we can break down the medical terms to find their meanings:
- The prefix cryo- comes from the Greek word kryos, which means cold or freezing.
- The suffix -surgery refers to operative procedures.
- Therefore, "cryosurgery" literally translates to surgery using extreme cold or freezing.
Analyze the other options
- needle biopsy: A procedure to obtain a tissue sample using a needle.
- ablation: The removal or destruction of body tissue (often using heat, lasers, or chemicals, though cryoablation is a sub-type, "ablation" on its own is a general term).
- prostate-specific antigen: A protein produced by cells of the prostate gland, measured via a blood test, not a tissue-freezing procedure.
Select the correct option
Based on the linguistic analysis of the prefix cryo-, cryosurgery is the procedure that specifically involves freezing tissue.
