If a male has high risk HPV strain linked to oral cancer. How often to get oral cancer screening when asymptomatic? Does it decrease mortality?

At least once a year. I would recommend getting an oral screening exam at least once a year. It can/should be combined with your annual exam at the dentist.
Periodic oral exam. The ADA recommends that an oral cancer screening should be completed at every periodic oral exam visit. At least 2 times per year.
