Salivary Gland Cancer
Salivary gland cancer is a less common type of head and neck cancer that develops in the salivary glands, which are responsible for producing saliva to aid digestion and keep the mouth moist. These glands are located in the mouth, cheeks, throat, and jaw area, with the three major pairs being the parotid, submandibular, and sublingual glands. While the exact cause of salivary gland cancer is unknown, risk factors include older age, exposure to radiation and certain workplace chemicals. Unlike other head and neck cancers, tobacco and alcohol use are not strongly linked to salivary gland cancer.
Preventing salivary gland cancer can be challenging due to its unclear causes, but reducing exposure to known risk factors like radiation and harmful workplace chemicals may help lower the risk. Regular dental and medical checkups can aid in early detection, which improves treatment success. Raising awareness about the symptoms and importance of early diagnosis can help individuals seek medical attention sooner, leading to better treatment outcomes and improved survival rates.
- Lump or swelling: The most common symptom of salivary gland cancer is the presence of a painless lump or swelling in the face, neck, or mouth. The lump may increase in size over time.
- Facial pain or numbness: Some individuals with salivary gland cancer may experience persistent pain in the face, mouth, or neck. In certain cases, there may be numbness or weakness in the face due to nerve involvement.
- Difficulty swallowing or opening the mouth widely: Salivary gland tumors that grow larger or are located near the throat can cause difficulty in swallowing or opening the mouth widely.
- Changes in facial appearance: As the tumor grows, it may cause changes in the shape or appearance of the face, such as asymmetry or swelling.
- Persistent ear pain: Tumors located in the parotid gland, which is situated near the ear, can cause persistent ear pain or discomfort.
- Fluid draining from the ear: In some cases, a tumor in the parotid gland can obstruct the normal drainage of fluid from the ear, leading to fluid discharge.
