    About Salivary Gland Cancer

    Salivary gland cancer is a form of cancer that starts in one of the multiple salivary glands located near and in the mouth. Tumors caused by this form of cancer can be malignant (cancerous) or benign (non-cancerous).

    According to the American Cancer Society, salivary cancer is very rare, affecting less than one percent of all cancer patients in the United States. The symptoms of salivary gland cancer are easily identifiable and if they appear, should be evaluated by a physician.

    Salivary glands come in pairs and there are three major types of them. They are the parotid glands, sublingual glands and submandibular glands.

    According to Seattle Cancer Care Alliance, approximately 80 percent of all salivary gland cancer tumors form in the parotid glands, with about 75 percent of those being benign. Ten to fifteen percent of tumors appear in the submandibular glands, with about 50 percent of them being benign.

    In addition to the three major types of salivary glands, there are hundreds of microscopic salivary glands located in the mouth, nose, sinuses and larynx.

    The following are some of the signs of salivary gland cancer.

    Muscle Weakness

    When salivary gland cancer develops, it may cause one side of the face or mouth to have muscle weakness. This can affect eating, speaking and smiling. It can be attributed to other causes, but is one of the more common signs of salivary gland cancer.

    Another one of the symptoms of salivary gland cancer is having difficulty with opening the mouth more than a small amount. The mouth cannot be opened very widely without difficulty and possibly not without pain.
