Causes & Risk Factors
Several factors can contribute to Salivary Gland Cancer.
The exact causes of salivary gland cancer remain largely unknown, making it different from cancers with clear environmental triggers like lung cancer and smoking.
The exact causes of salivary gland cancer remain largely unknown, making it different from cancers with clear environmental triggers like lung cancer and smoking. What scientists do know is that cancer develops when normal cells in the salivary glands undergo genetic changes that cause them to grow and divide uncontrollably. These cellular changes can happen randomly over time or may be influenced by certain risk factors.
Some research suggests that radiation exposure may play a role in developing salivary gland cancer.
Some research suggests that radiation exposure may play a role in developing salivary gland cancer. People who received radiation therapy to the head and neck area for other medical conditions show higher rates of these tumors years later. Additionally, certain workplace exposures - particularly in industries involving rubber, asbestos, or woodworking - have been linked to increased risk, though the connections aren't fully understood.
Unlike many other cancers, lifestyle factors like diet, alcohol consumption, and smoking don't appear to significantly increase salivary gland cancer risk.
Unlike many other cancers, lifestyle factors like diet, alcohol consumption, and smoking don't appear to significantly increase salivary gland cancer risk. This makes prevention challenging since many cases seem to develop without clear preventable causes. However, some viral infections, including Epstein-Barr virus, have been found in certain types of salivary gland tumors, suggesting infection might contribute to cancer development in some cases.
Risk Factors
- Previous radiation therapy to the head or neck
- Age over 50 years
- Male gender (slightly higher risk)
- Occupational exposure to rubber, asbestos, or wood dust
- Family history of salivary gland tumors
- Certain viral infections like Epstein-Barr virus
- Exposure to radioactive substances
- History of other head and neck cancers
Diagnosis
How healthcare professionals diagnose Salivary Gland Cancer:
- 1
Diagnosing salivary gland cancer typically begins when someone notices a persistent lump or experiences facial symptoms that don't resolve.
Diagnosing salivary gland cancer typically begins when someone notices a persistent lump or experiences facial symptoms that don't resolve. During your initial visit, the doctor will examine your head, neck, and inside your mouth, feeling for lumps or enlarged lymph nodes. They'll ask about your symptoms, medical history, and any previous radiation exposure. The physical examination helps determine which salivary glands might be affected and whether the tumor feels mobile or fixed to surrounding tissues.

Imaging studies provide crucial information about the tumor's size, location, and relationship to nearby structures.
Imaging studies provide crucial information about the tumor's size, location, and relationship to nearby structures. CT scans or MRI imaging can show detailed pictures of the salivary glands and help determine if cancer has spread to lymph nodes or other areas. Sometimes doctors order specialized scans like PET scans to look for cancer elsewhere in the body. These tests also help surgeons plan the best approach if surgery becomes necessary.

A definitive diagnosis requires examining tissue under a microscope, usually obtained through fine needle aspiration or a small surgical biopsy.
A definitive diagnosis requires examining tissue under a microscope, usually obtained through fine needle aspiration or a small surgical biopsy. Fine needle aspiration involves inserting a thin needle into the tumor to extract cells for analysis. If this doesn't provide enough information, a larger tissue sample may be needed. The pathologist's examination determines not only whether cancer is present but also identifies the specific type, which is crucial since different types of salivary gland cancer behave differently and require different treatment approaches.
Complications
- Salivary gland cancer and its treatment can lead to several complications that significantly impact quality of life.
- Facial nerve damage during surgery may cause weakness or paralysis on one side of the face, affecting your ability to smile, close your eye completely, or control facial expressions normally.
- While some nerve function may return over time, permanent changes are possible, particularly with more extensive tumors that require aggressive surgical removal.
- Dry mouth, or xerostomia, commonly develops after radiation therapy to the salivary glands and can persist long-term.
- This condition affects more than comfort - it increases risk of tooth decay, gum disease, and mouth infections since saliva plays a crucial role in maintaining oral health.
- Difficulty swallowing, changes in taste, and problems with speech may also occur, particularly when multiple salivary glands are affected or when treatment involves significant portions of the mouth and throat area.
- These complications often require ongoing management through dietary modifications, artificial saliva products, and specialized dental care.
Prevention
- Unlike cancers with clear preventable causes, salivary gland cancer offers limited opportunities for prevention since most cases develop without identifiable risk factors.
- However, you can take some protective steps that may reduce your risk.
- If you work in industries with potential exposure to harmful substances like asbestos, rubber processing chemicals, or wood dust, following proper safety protocols and using protective equipment is essential.
- Avoiding unnecessary radiation exposure represents another preventive measure, though this must be balanced against legitimate medical needs.
- If you require medical procedures involving radiation to the head and neck area, discuss the risks and benefits with your healthcare team.
- Keep records of any radiation treatments you receive, as this information becomes important for future medical care and cancer screening.
- Maintaining good oral hygiene and regular dental checkups can help detect changes in your mouth early, though these practices don't directly prevent salivary gland cancer.
- Some research suggests that maintaining a healthy immune system through good nutrition, regular exercise, and adequate sleep might help your body's natural defenses against cancer development, though direct evidence for salivary gland cancer prevention is limited.
Surgery remains the primary treatment for most salivary gland cancers, with the specific approach depending on the tumor's location, size, and type.
Surgery remains the primary treatment for most salivary gland cancers, with the specific approach depending on the tumor's location, size, and type. For parotid gland tumors, surgeons perform a parotidectomy, carefully removing part or all of the gland while preserving the facial nerve that controls facial expressions. Submandibular gland tumors typically require complete removal of the affected gland. The complexity of these surgeries stems from the close proximity of important nerves and blood vessels that must be preserved whenever possible.
Radiation therapy often follows surgery, especially when tumors are large, high-grade, or when surgical margins are close.
Radiation therapy often follows surgery, especially when tumors are large, high-grade, or when surgical margins are close. Modern radiation techniques can precisely target the tumor bed while minimizing exposure to surrounding healthy tissues. Some patients receive radiation therapy as their primary treatment if surgery isn't possible due to tumor location or patient health factors. The radiation is typically delivered in daily sessions over several weeks.
Chemotherapy plays a more limited role in salivary gland cancer compared to other cancer types.
Chemotherapy plays a more limited role in salivary gland cancer compared to other cancer types. It's most commonly used for advanced or metastatic disease, often in combination with radiation therapy. The specific chemotherapy drugs chosen depend on the tumor type and individual patient factors. Clinical trials are exploring newer targeted therapies and immunotherapies that may offer additional options for certain types of salivary gland cancer.
Reconstructive surgery may be necessary after tumor removal, particularly when significant amounts of tissue are removed or when facial nerves are affected.
Reconstructive surgery may be necessary after tumor removal, particularly when significant amounts of tissue are removed or when facial nerves are affected. Plastic surgeons can often restore facial symmetry and function through various techniques. Speech and swallowing therapy may help patients adapt to changes in mouth function, while dental care becomes especially important if radiation therapy affects saliva production.
