How to say "biopsy" in Japanese

• 生検せいけん
  nounThe standard medical term for a biopsy as a tissue-sampling procedure. Use this in clinical or medical contexts; it is the form normally found in hospitals and medical literature.
• バイオプシー
  nounA loanword covering the same medical sense. It is less common and largely redundant with 生検, so it is seldom the word you want; use it mainly when the foreign-sounding term itself is intended.

Both terms mean the medical procedure of taking a tissue sample for examination; 生検 is the established clinical term, while 「バイオプシー」 is a less common loanword alternative.
