Today I went to the dentist and they had this nifty new contraption - it looked like a space age hair dryer with blue lights coming out of it. She was scanning my mouth with it, and it turns out, looking for evidence of oral cancer. Apparently this type of cancer is really hard to catch until it is advanced to the metastasis stage, so this is a great breakthrough in oral health. Another interesting tidbit there is that the demographics of oral cancer patients is changing - from older men who are smokers and boozers to younger women. There is some hypothesis about it being linked to HPV, the sexually transmitted human papilloma virus. Not sure how they will ever establish a link, given the Guardasil vaccine, but I'm hedging my bets against cancer regardless! Another good reason to go to the dentist. Mine is super friendly and has a great magazine selection along with her anti-cancer equipment so I would be happy to give you a recommendation!
