What is Unknown Primary Head and Neck Cancer?

Unknown Primary Head and Neck Cancer occurs when malignant (cancerous) squamous cells spread to the lymph nodes in the neck or around the collarbone.

Squamous cells, which look like thin, flat cells that resemble fish scales, are found in many of the body’s tissues, including the skin, respiratory tract and lining of the paranasal sinuses and nasal cavity. Cancer can develop in squamous cells that are anywhere in the body and can metastasize, or spread, to other parts of the body through blood or the lymph system.

If you are diagnosed with a Head and Neck Cancer, your doctor will locate where in your body the cancer began, which is called the primary tumor. For example, if lung cancer spreads to the neck, the cancer cells in the neck are lung cancer cells and are treated the same as the cancer in the lung.

If the primary tumor cannot be located, this is called Unknown Primary Head and Neck Cancer (sometimes referred to as metastatic squamous neck cancers).

Prognosis and treatment options vary depending on each person’s own genetic makeup, location of the cancer cells and the stage of the cancer.
