It makes sense that to make money on Adsense that the highest paying on Adsense that the highest paying keywords will make more money.  It's rumored that mesothelomia is a $45 word.  While Google won't give out that information we can say without contradiction that when doing a search we turned up 250,000 clicks. 

Since the race to find the highest paying keywords continues, let's give some thought to actually making money with those words, mainly, how can traffic be driven to such expensive words? 

Using Adwords to drive traffic to an mesothelomia Adsense site stands to reason would be expensive-about $45 per keyword, if you get my drift.
