Salivary Gland Cancer

Definition

Salivary gland cancer forms in the tissues of the salivary glands, which produce saliva to aid digestion and keep the mouth moist. It can occur in the major salivary glands (parotid, submandibular, sublingual) or in minor glands throughout the mouth and throat.

Characteristics

There are many types of salivary gland tumors, both benign and malignant. Symptoms may include a painless lump near the ear, jaw, or inside the mouth, facial numbness or weakness, trouble swallowing, or persistent pain in the area.

Diagnosis and Prognosis

Diagnosis involves physical exams, imaging tests (MRI, CT scans), fine-needle aspiration biopsy, and sometimes surgery for tissue analysis. Prognosis depends on the tumor type, grade, size, and whether it has spread to nearby tissues.

Treatment

Treatment usually starts with surgery to remove the tumor, often followed by radiation therapy. Chemotherapy is less commonly used but may be considered for advanced or recurrent cases.
