Salivary gland cancer can be prevented by avoiding the possible risk factors namely tobacco and alcohol. The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) for the US were established. Most superficial lesions can be removed with simple enucleation. The distinction between tumor types can be difficult, particularly based on material from fine-needle aspiration (FNA). About 20% of parotid tumors are malignant, with higher percentages for children, for the submandibular gland, and for intraoral minor salivary glands. It is important to recognize that the clinical behavior of a tumor rather than the histology can provide a better treatment guide, and it is recommended that clinical factors, in addition to histology and grade, are considered when treatment planning.

Salivary glands are a common source of benign pathology; malignant tumors are rare. Low-grade or well-differentiated tumors usually behave benignly, intermediate ones are more aggressive and high-grade, or undifferentiated tumors metastasize early to regional lymph nodes and carry a poor prognosis. 1: digastric muscle 2: main trunk of the facial nerve 3: cervical branch of the facial nerve 4: marginal mandibular branch of the facial nerve 5: great auricular nerve divided distally.

It is less common for a cancer arising in a location below the collarbone to spread to the gland.. Eisele says that tumor surgery on one parotid gland is not likely to affect a persons saliva level since there are so many other salivary glands that can compensate. Neoplasms (benign and malignant) are more likely to be present in. Adjuvant radiotherapy is recommended for large tumors (greater than 4 cm), patients with incomplete or close margins, recurrent disease, perineural and vascular invasion, nodal disease, in metastatic disease, and is usually indicated for adenoid cystic carcinomas and high-grade tumors.
