Disease Analysis: Head and Neck Cancer

Head and neck cancers (HNCs) are defined as any cancer that begins in cells of the oral cavity, pharynx, nose, sinuses, or salivary glands. These cancers are grouped together due to historical similarities in etiology, disease presentation, and manifestation. The vast majority of these cases (90%), collectively referred to as head and neck squamous cell carcinomas (HNSCCs), appear in squamous epithelial cells lining the mucous membranes of these regions. The exception to this is salivary gland cancer, which can appear in any of the salivary glands’ diverse cell types.
