Biopsy
A biopsy is a medical procedure that involves taking a small sample of body tissue so it can be examined under a microscope.
Imaging techniques, such as X-ray, ultrasound, CT scanning or MRI scanning is often used to guide many types of biopsy.
Biopsies are usually straightforward procedures that are carried out using local anaesthetic. In most cases, biopsies are outpatient procedures, so you won't need to stay in hospital overnight.
