People with the conditions listed in this trial can participate as controls.Key Inclusion Criteria:
1. Patients with malignant tumors seen at the Stanford University Cancer Center. Eligible patients will have a diagnosis of squamous cell carcinoma (HNSCC) and will have been seen in the Stanford Head and Neck Oncology Program.

- FNA
- Core needle biopsy
- Cup forceps or punch biopsy of<4mm.
4. Informed consent documented prior to procedure
