Cancer sucks. And Iowa, once again, has the second highest cancer rate in the country. Our cancer rates are rising faster than any state, so unfortunately we could soon be number one in America. 

Sometimes I hear, “Oh, it is because Iowa has more old people.” Age does matter when it comes to cancer, but that is not the reason; Iowa’s median age (39.1) is near the national median (39.2) and the same as states whose cancer rates are dropping. 

As a cancer research scientist, I’ve read and heard many opinions about what might be causing Iowa’s cancer problem. Cancer is multifactorial, meaning many chemicals (and UV light) can cause and promote it, making it a big challenge to pinpoint primary causes.
