"Something strange is going on in medicine," writes the New York Times's Gina Kolata - major diseases are are on the wane, and in some cases, it's a mystery as to why.
A decline in mortality from colon cancer is "especially perplexing," writes Kolata - a decline by nearly 50 percent since its peak in the 1980s has left researchers searching for an answer, since more screening couldn't possibly indicate such a large decline.
