Salivary glands produce saliva, which keeps the mouth moist and helps the body with digestion.
The mouth contains many salivary glands, some major and some minor. Salivary gland cancer occurs when one of these glands develops a cancerous tumor. There are 450-750 microscopic minor salivary glands all around the mouth. Locations include: the sinuses, the tongue, inside the cheeks, the nose, the larynx and voice box.
Tumors are less likely to occur in these minor glands, but if one does develop, there is a 50-50 chance that it will be cancerous, or malignant.
