Why has the incidence of non-Hodgkin's lymphoma increased so dramatically?

Why has the incidence of non-Hodgkin's lymphoma increased so dramatically?

The answer to the question of why non-Hodgkin's lymphomas have increased in incidence over the past thirty years may go toward the ability to diagnose these cancers earlier, and because I see an increased incidence of lots of cancers across the board, and especially in younger patient populations. So, it's hard for me to single out one particular cancer from others as being in increased incidence. In my opinion, the most significant cause of cancers, and lymphoma in particular, is probably environmental impact and environmental exposures. Whether it is radiation exposure, toxin exposure, or pesticide exposure, the use of these products (although getting better in the United States) is still a significant problem and a significant health exposure across the world. I think the more we are exposed to toxic agents, the more likely we are to end up with other cancers in the future.
