Throat cancer is on the rise in New Zealand and it appears oral sex is to blame.
New data from the New Zealand Cancer Registry shows that the number of New Zealand men diagnosed with cancer has nearly doubled in the last 25 years.
There were more than 100 cases of throat cancer diagnosed in 2013 alone (96 of those were men, 26 were women).
"We're seeing younger professionals who are otherwise healthy (getting cancer)," Dr Julian White told Fairfax.
Oral sex carries the risk of contracting human papillovirus, a common sexually transmitted infection (STI) that has been shown to cause cancer.
