  • Oropharyngeal cancer: This type of cancer affects the area in the throat that includes the tonsils.

Laryngeal cancer affects the larynx or the voice box along with the vocal cords. They are further classified into

  • Glottic cancer: This cancer affects the cells of the vocal cords.
  • Supraglottic cancer: It affects the upper regions of the voice box and the cells of the epiglottis
  • Subglottic cancer: The lower parts of the larynx just below the vocal cords are affected

3.Lip and oral cavity cancer:

It affects the squamous cells that line parts of the mouth that includes lips, mouth, gums and tongue, but it can go deeper into the inner tissues of the mouth.
