This month cubed investigates a new technique to identify the presence of cancerous cells. Clinicians at the Maidstone and Tunbridge Wells NHS Trust in Kent are pioneering a test, reducing the need for invasive surgery. Breast Surgeon Peter Jones explains the ‘sentinel lymph node biopsy’ which involves injecting microbubbles into tissue. Using a special ultrasound machine the radiologist can see the bubbles travel to the sentinel lymph node. If a small needle biopsy is then tested positive, the lymph glands can be removed in one operation. For breast cancer patients, this can reduce extra stress and anxiety.
