Brief Summary
Lymphoma diagnosis often involves removal and biopsy of one or more lymph nodes. Many (around half) of these diagnostic procedures show that no cancer is present, hence unnecessary removal results in numerous side effects and complications. The procedure is also highly invasive. The investigators have already shown that it is possible to tell the difference between healthy and diseased tissue in the laboratory by looking at the light emitted by tissue when a low power laser is shone on to it. The investigators intend to use this technique, known as "Raman Spectroscopy" (RS) to tell if tissue in the node is cancerous or healthy. By combining RS with a fine needle, the technique can target tissues below the skin with minimal invasion. Our needle will provide the clinician with instant diagnosis without the delay and cost of a laboratory analysis by pathologists. The investigators have designed a probe that slides through a fine needle, guided by ultrasound, to the lymph node. The space between the two needles provides space for cell aspirate. The investigators propose to measure spectra from excess lymph node biopsy samples taken during standard routine diagnostic biopsy. The investigators are also interested to see if they can successfully extract a fine needle aspiration (FNA) biopsy sample using the device, as well as record a RS measurement. If successful this would ease clinical adoption as the study could run in parallel with existing standard routine clinical practice, using just one device. This study will evaluate the new device on half a lymph node that will be excised and snap-frozen during a routine surgical biopsy, to gather data for submission of approvals for an in-vivo study to follow.

Eligibility Criteria
Patients undergoing surgical head \& neck lymph node biopsy within Gloucestershire Hospitals NHS Foundation Trust Patients with a lump in their head or neck are sometimes referred by their GP for a biopsy. This often first involves taking a small sample of cells with a fine needle, guided by ultrasound, called a Fine Needle Aspiration (FNA) biopsy. If the result from this FNA biopsy is inconclusive, then they are often further referred for a surgical biopsy. Gloucestershire Hospitals NHS Foundation Trust is a tertiary referral centre for surgical head and neck biopsies.
You may qualify if:
- Patients undergoing biopsy or excision of lymph nodes as part of their routine clinical care within Gloucestershire Hospitals NHS Foundation Trust.
- Patients undergoing lymphadenectomy as part of routine treatment
You may not qualify if:
- Patients unable to consent to the study due to communication difficulties
- Patients unable to consent to the study due to lack of capacity
