Claims this source supports

• A biopsy involves removing a sample of cells or tissue; a doctor or specialist should tell you if you need to do anything before your biopsy and you can ask them about any concerns or questions you have.
• You'll usually have local anaesthetic to numb the area. This means you'll be awake but will not feel any pain. You may also be given medicine to help you relax (sedation).
• Some biopsies are done under general anaesthetic, meaning you're asleep during the procedure.
• You can usually go home the same day after having a biopsy.
