Does travel or living abroad contribute to lymphoma risk?

This one is a shot in the dark. As you might have read by my story, I travel and occasionally live outside the US as a dutiful public servant. My diagnosis came after living two years in India although I can't really blame India (such a nice country really). I'm well aware that people come down with lymphoma who haven't wandered far from their hometown let alone travelled extensively. But, it does beg the question - if you do travel, especially to third world countries, does your risk of getting lymphoma increase? Looking at the risk factors out in the last two weeks, we are exposed to more x-rays in airplanes and there are more PCBs and dioxins in the water of some countries. Hard to quantify this though.
