Cancer of salivary gland is a malignant tumor of tissues that produce saliva. Cancer begins when the cells in the body become abnormal and start to multiply without control or order. These cells form a growth of tissue called a tumor which can be benign or malignant. Usually, a benign tumor isn’t cancerous and can be removed without growing back while a malignant tumor is cancerous which can invade and damage the healthy tissues and organs in the body. 

The most cancerous tumors in the body begin in the largest of the salivary gland which is a parotid gland that is found on either side of the face, in front of the ears as well as submandibular glands which are found under the jawbone. This cancer can also begin in the minor salivary glands. About 80 percent in the parotid gland and about half of the tumors in the submandibular gland are noncancerous while almost always malignant in the sublingual gland tumors. If you experience any symptoms listed below, book an appointment to see a doctor.
