Metastatic squamous neck cancer with occult primary is a disease in which squamous cell cancer spreads to lymph nodes in the neck and it is not known where the cancer first formed in the body. Signs and symptoms of metastatic squamous neck cancer with occult primary include a lump or pain in the neck or throat.
Head and neck cancer is a general term used to refer to a range of different cancers that start developing in the head and neck region of the body. This includes the oral cavity, the tongue, palate, jaw, salivary glands, the throat (larynx) and the nose. Head and neck cancer occurs when malignant tumours grow in any of the tissue or lymph nodes in the head or neck. Not all tumours in the head and neck are malignant.
