Salivary gland cancer is a rare cancer. Possible symptoms include:
- a painless lump or swelling in your jaw, cheek, mouth or neck
- numbness in a part of your face
- drooping on one side of your face (facial palsy)
- pain in the area of the lump or swelling
- problems swallowing
- difficulty opening your mouth fully
- swelling on one side of your face
Many of these signs and symptoms can be caused by benign (non-cancerous) salivary gland tumours or by other conditions.
It is important to get any unusual symptoms checked out by your doctor. They can examine you and do further tests if necessary.
