The most common symptoms of head and neck cancer are:

• pain in the mouth, upper teeth, throat, neck, face or chin
• a lump or sore that does not go away
• bleeding in the mouth or through the nose
• white or red patch on the gums, tongue or lining of the mouth
• difficulty or pain when swallowing or chewing
• changes in the voice, such as hoarseness
• headache
• pain, pressure or ringing in the ears, or problems hearing
• blocked or chronically infected sinuses
• swelling under the chin or in the jaw
• numbness or paralysis of the muscles in the face
• a cough that does not go away
• trouble breathing or speaking
• coughing up blood
• swelling or other problems with the eyes, such as double vision
• decreased sense of smell.

Many conditions can cause these symptoms, not just head and neck cancer. If you have any of these symptoms, you should talk to your doctor.
