What Salivary Glands Are and Their Role

Salivary glands are parts of the mouth that make saliva, commonly called spit. Saliva helps keep your mouth moist, making it easier to chew, swallow, and begin digesting food. It also helps clean your mouth and contains antibodies that fight germs. Humans have three main pairs of large salivary glands: the parotid glands (in front of and below the ears), the submandibular glands (under the jaw), and the sublingual glands (under the tongue). In addition, there are hundreds of smaller glands lining the mouth and throat.

Why Salivary Glands Matter in Cancer Care

Salivary gland cancer is a rare form of head and neck cancer where malignant cells grow in these glands. Because saliva is important for mouth health and digestion, cancer or its treatment can affect these functions. The cancer’s behavior and treatment depend on which gland is involved, the size and stage of the tumor, and the type of cancer cells. Risk factors include older age, previous radiation therapy to the head or neck, and exposure to certain substances at work. However, many people with salivary gland cancer have no known risk factors.

Signs, Symptoms, and Diagnosis

Salivary gland cancer may not cause symptoms early on. When symptoms do appear, they can include a painless lump or swelling near the ear, cheek, jaw, lip, or inside the mouth. Other signs may be fluid draining from the ear, difficulty swallowing or opening the mouth widely, numbness or weakness in the face, or persistent facial pain. Because these symptoms can also be caused by other conditions, doctors use a combination of physical exams, imaging tests like MRI or CT scans, and biopsy (taking a small tissue sample) to confirm the diagnosis. It’s important that tissue samples are reviewed by a pathologist experienced in salivary gland cancers, as these tumors can be complex to identify.

Understanding the Term in Your Care

If you hear “salivary gland” mentioned in your medical records, test results, or treatment plans, it refers to the glands that produce saliva and may be the site of a tumor or other condition. This term alone does not mean cancer or a specific treatment. Instead, it is part of a larger picture that includes the type of cells involved, the tumor’s size and location, and your overall health. Always ask your care team to explain what the term means for your individual case and how it affects your diagnosis and treatment options.

Common Questions to Ask Your Care Team

You might want to ask: Which salivary gland is affected? What type of tumor or cancer cells are present? What stage is the cancer, and what does that mean for treatment? What are the possible side effects of treatment on saliva production and mouth health? Are there ways to manage symptoms like dry mouth or difficulty swallowing? Understanding these details can help you feel more informed and involved in your care.
