Family and friends

  • Oral HPV is not casually transmitted by sharing drinks or kissing on cheeks.

Partners of people with throat cancer

New sexual partners in the future

When did I get this infection?

  • It is impossible to know the time from first oral HPV infection to cancer, but it takes many years. Therefore, it is not possible to know when and from whom the infection was acquired.
  • HPV is common and the great majority of people who acquire it will clear the infection and never have any evidence of having had an infection.

What does having HPV in my tumour mean?

  • Throat cancer patients with HPV in their tumour live longer, on average, than people without HPV (i.e. HPV-positive tumours usually respond well to therapy).
  • However, patients who smoke tobacco or have smoked for a long time in the past do not live as long, on average, as patients who have never smoked. Current smokers are strongly encouraged to stop. Help is available.
