Oral sex linked to rising throat cancer cases among adults

The UK and US are experiencing a significant rise in throat cancer cases, with a 35% increase in incidence rates since the early 1990s. While smoking has traditionally been blamed for these cancers, medical experts are now pointing to oral sex as a potential contributing factor. Dr. Hisham Mehanna from the University of Birmingham highlights that 70% of throat cancer cases are linked to the human papillomavirus (HPV), which can be transmitted through oral sexual activities. Individuals with multiple oral sex partners face a nine-fold increased risk of developing oropharyngeal cancer. Research indicates that around 80% of people will carry HPV at some point, with a third of the population infected at any given time. HPV strains 16 and 18 are particularly associated with oropharyngeal cancer, as the virus can infect the throat or tonsils during oral sex. Men are more frequently affected by these cancers, although the relative risk of cunnilingus compared to fellatio in terms of HPV transmission remains unclear. Notable figures, such as Michael Douglas, have publicly discussed their experiences with throat cancer, attributing their conditions to oral sex. The HPV vaccine, which is over 80% effective, is available in many developed countries and has been shown to reduce the incidence of head and neck cancers, in addition to cervical cancer. Experts emphasize the importance of early detection in cancer treatment, as highlighted by the recent diagnosis of presenter Jamie Theakston with stage one laryngeal cancer. Increased awareness and screening can lead to better outcomes, as one in two individuals will face some form of cancer in their lifetime.
