An infection will cause dramatic symptoms, while a malignant tumor will keep a low profile. Some of these tumors can be cancerous (malignant). In this edition, several chapters were revised and its addresses from the molecular issues of cancer sciences to the clinical practice in medical oncology. Most salivary gland tumors are benign and occur in the parotid glands. Approximately 85 percent arise in the parotid; the remainder originate in the submandibular, sublingual, and minor salivary glands, which are located throughout the submucosa of the mouth and upper aerodigestive tract ( figure 1 ) [ 1 ].
