The term \”head and neck\” includes several regions where cancer can develop. Head and neck cancers refer to tumors that develop in one of these regions:

• oral cavity (tongue, the top area of the mouth, the lower area of ​​the mouth, tongue base, tonsils, lips);
• the anterior region of the mouth or throat (oropharynx);
• Lower throat (hypopharynx)
• upper throat (nasopharynx);
• larynx (including supraglottis, glottis, and subglottis);
• salivary glands;
• nose and sinuses.

Although these types of cancers are different, they are treated similarly, so they are considered as a group. Except for cutaneous and thyroid cancers,> 90% of head and neck cancers are squamous cell carcinomas, and the rest are generally adenocarcinomas, sarcomas, and lymphomas.

Other head and neck tumors are:

• Intracranial tumors in adults
• Intracranial tumors in children
• Thyroid tumors
• Tumors of the orbit and cancers affecting the retina
• Acoustic Neurom
• Skin cancer
