Areas Affected

• Nasal cavity: The space inside the nose.

• Mouth: Including the oral cavity.
• Salivary glands: Glands responsible for saliva production.
• Throat: The passage leading from the mouth to the stomach and lungs.
• Larynx: Also known as the voice box.

Risk Factors

• Alcohol Consumption: Heavy alcohol use can increase the risk.
• HPV infection: Infection with human papillomavirus (HPV), a common sexually transmitted virus.
• Ultraviolet Light Exposure: Sun exposure or exposure to artificial UV rays, a major cause of lip cancer.
• Occupational Exposures: Including exposure to wood dust, formaldehyde, asbestos, nickel, and other chemicals.
• EBV virus: Infection with the Epstein-Barr virus can increase risk.
• Radiation: Prior radiation treatments to the head and neck region.

HPV and Head and Neck Cancer

Approximately 70% of cancers in the oropharynx are attributable to HPV.

Sex Ratio and Age

Men are about twice as likely as women to be diagnosed with head and neck cancers, and these cancers are more common in individuals over 50 years of age.

Symptoms

Dependent on the area affected:

• Mouth: White or red sores, swelling in the jaw, unusual bleeding or pain, and problems with dentures.
• Pharynx: Difficulty breathing or speaking, pain or ringing in the ears, trouble swallowing.
• Larynx: Pain when swallowing, ear pain.
• Sinuses and Nasal Cavity: Chronic sinus blockage, frequent sinus infections, nosebleeds, headaches, and dental problems.

Prevention
