Selection 31 - Living Downstream : An Ecologist looks at Cancer and the Environment

An interesting fact is that "Deaths of adoptive parents from cancer before the age of 50 increased the rate of mortality from cancer fivefold among the adoptees. . . Deaths of biological parents from cancer had no detectable effect on the rate of mortality from cancer among the adoptees" (Sandra Steingraber). There was on article called "Scientists identify Gene Responsible for Human Bladder Cancer" the article tells us about how they "located the segment of DNA responsible for the transformation. And by comparing this segment to its unmutated form in noncancerous human cells, they were able to pinpoint the exact alteration that had caused a respectable gene to go bad" (Sandra Steingraber).  But they also found this segment in other cancers as well.  The rate of bladder cancer increased 10% between 1973 and 1991.  It was attributed among women who smoked cigarrettes.  On the other hand, we need to start imagining our alternative future and so we begin with a retrospective view for two reasons.  First, we carry many carcinogens in our that are not being used but kept domestically, and second we need to find out what pesticides were sprayed in neighbourhoods and what sorts of chemicals they contain.  Overall, cancer is in peoples genes and cannot as of right now be fully cured, we need to look into our future and see what we can do to help stop the spread of it and do our best to find a way to help ourselves to be more prepared.
