2. Head & Neck Cancer: Incidence of Cancer of the Lip, Oral Cavity, or Pharynx in Males by World Region Cancers of the lip, oral cavity, and pharynx are reported at varying rates among males around the world. These cancers are most common in Western Europe, Southern Africa, Australia, and New Zealand, and least common in Japan and Northern Africa .
1. Head & Neck Cancer: Worldwide Incidence and Mortality (estimated) The most common cancers of the head and neck are those occurring in the mouth and/or pharynx. Worldwide, these cancers account for more than 360,000 new cases and nearly 200,000 deaths annually. Overall, the incidence of these cancers is approximately 2.5 times greater in men than women.
9. Head & Neck Cancer: Anatomy The most common sites for head and neck tumors are the oral cavity, pharynx, paranasal sinuses, and larynx. Approximately 50% of all cases are in the oral cavity and oropharynx, and one-third are in the larynx.
10. Head & Neck Cancer: Lymph Node Regions Head and neck cancers of the oral cavity and/or nasopharyngeal regions may involve several major lymphatic chains. These chains contain nearly 200 lymph nodes that run parallel to the jugular veins, the spinal accessory nerve, and the facial artery, and into the submandibular triangle. .
11. Head & Neck Cancer: Sites The anatomy of cervical lymph nodes has been classified into five levels to aid in the description of head and neck cancers. An understanding of the anatomical location of regional lymph nodes in the head and neck, as well as the drainage patterns through these vessels, is critical to diagnosis and management of cancers in these regions.
17. Head & Neck Cancer: Distribution by Stage of Newly Diagnosed Disease Among patients with newly diagnosed head and neck cancers, 40% have localized disease and up to 50% have regional disease. Less than 10% of patients newly diagnosed with head and neck cancers have distant metastases.
