I have been working for a long time trying to help figure out why people get cancer. One of my major interests has been in the possible role of iron overload. Largely on the basis of this work, published in the Journal of National Cancer Institute and the New England Journal of Medicine, the Swedish food industry decided to cease iron fortification of flour in the early 1990s.

Also, a perplexing challenge, which I had begun to engage in the late 1970s, is the confounding mystery of why breast cancer risk rises so dramatically as societies industrialize. In 1987, I proposed a radical new theory that use of electric lighting, resulting in lighted nights, might produce "circadian disruption" causing changes in the hormones relevant to breast cancer risk. Accumulating evidence has generally supported the idea, and it has received wide scientific and public attention. For example, my work on this has been featured on the covers of the popular weekly Science News several times (first on October 17, 1998) and the scientific journal Cancer Research (July 15, 1996).  Since then, media interactions have been too numerous to list. Public outreach is important because it is "communcation of science to the people who pay for it".
