Q: What is ‘needlehole’ surgery?

Answer: 

Needlehole treatment, or needlehole surgery, is a series of treatment methods using needles alone to take biopsies and destroy suspicious areas of tissue. The tissues are destroyed by means of energy directed down the needle. This is called ‘ablation’. It is a much less invasive practise than laparoscopic surgery (‘keyhole surgery’.)
