  • smoking
  • weakened immune system
  • poor oral hygiene
  • chronic inflammation
Risk Factors

  • Oropharyngeal cancers are more common in white men
  • HPV infection is linked to sexual behaviors such as open mouth kissing and oral sex.
Development
  • HPV related cancers occur on the tonsillar area, the base of the tongue and the oropharynx
  • Non-HPV positive tumors tend to involve the anterior tongue, floor of mouth, mucosa of the cheeks and alveolar ridges
