Reckless reporting by stupid journalists. They are talking about relative risk increase instead of absolute and don't even mention the baseline risk.

If 3 in 10,000 humans get one type of cancer and a certain lifestyle makes that 4 in 10,000 may get that type of cancer that is a relative risk increase of 25%!!!

The baseline risk (mentioned in the study) to get throat cancer is 0.013 %. The risk among the study participants admitting(?) to have had oral sex is 0.11 %. You need a headline? OK, calculate by which factor you have to multiply 0.013 to get 0.11. That's a nice big figure (relative risk increase) that may sell the paper. People enjoy to be scared.
