Dogs Can Smell Cancer

Dogs can smell cancer.  These researchers have trained dogs to sit when they smell lung cancer and they got it right 99% of the time.  This is not new news.  I wonder why it hasn't been applied more globaly?  Is it a shortage of cancer researchers who also know how to train dogs?
