Not that you can always trust the overture search tool #, but if you use it for the word cancer, "mesothelioma cancer" comes up with more searches than skin cancer, lung cancer etc. Obviously it isn't as widespread as any of the other ones, so it doesn't make sense.
I'm not sure if this is a glitch, or if it is all of the people who built adsense sites doing searches for their sites and clicking ads.....
