Is it possible for an epidemic to be invisible?

Since 1991 the annual number of newly documented cases of thyroid cancer in the United States has skyrocketed from 12,400 to 62,450. It’s now the seventh most common type of cancer.

Relatively little attention is paid to the butterfly-shaped thyroid gland that wraps around the throat. Many don’t even know what the gland does. But this small organ (and the hormone it produces) is crucial to physical and mental development, especially early in life.

Cancer of the thyroid also gets little attention, perhaps because it is treatable, with long-term survival rates more than 90 percent. Still, the obvious question is what is causing this epidemic, and what can be done to address it?

Recently, there has been a debate in medical journals, with several authors claiming that the increase in thyroid cancer is the result of doctors doing a better job of detecting the disease at an earlier stage. A team of Italian researchers who published a paper last January split the difference, citing increased rates and better diagnosis. But as rates of all stages of thyroid cancer are soaring, better detection is probably a small factor.

So, what are the causes?
