What We Found
Overall, from 1979 to 1996, Love Canal residents got cancer at about the same rate as people of similar age and sex in both Niagara County and in upstate New York. These comparisons are based on the actual number of cancers among the Love Canal residents (304 cancers) compared to the number of cancers expected if they had the same cancer rates as Niagara County (332) or upstate New York (325). We found that some types of cancer were somewhat higher among former Love Canal residents (e.g. kidney, bladder, and respiratory) compared to upstate New York. Other types of cancer were somewhat lower. Additional comparisons are in the full paper.
There were 268 cases of cancer in those residents who also had complete interviews. For the most part, we did not see a big difference in the cancer rates in these people, depending on when and where they lived at the Canal. However, we did find a significant increase in the risk of bladder and kidney cancers for those who were exposed as children. We also found an increase in the risk of liver and rectal cancers for people who lived on a hot spot (areas with greatly elevated chemical levels) or swales (low, wet areas). The number of cases is small for many of these cancer types, however, so determining whether there is a pattern is difficult. Some of our findings (especially for bladder and kidney cancers) are similar to those of other studies of persons exposed to chemicals like those found at Love Canal.
I can't wait till humans evolve into an intelligent species.
