Before our class lectures, I was not too informed about what causes cancer, partially because I have not known anyone very close to me that has been diagnosed with cancer – my understanding was that it was caused by mostly environmental factors and genetics along with very little influence from other factors presented in the reading such as poor diet and energy expenditure, but some of the factors presented were new to me (i.e. co-evolution with pathogens, evolved capacities for defense). Upon reflection, none of the article’s claims are surprising or immediately questionable. The article mentions that cancer is a disease that is not new to our modern environment, however, sometimes due to mismatch, certain types of cancer are obviously more common within it. Since cancer is majorly influenced by culture or lifestyle, this means that developed nations such as the United States are plagued with cancer more easily and more often, another throwback to our lessons concerning the negative consequences of industrialization. I think the most interesting part of the article is when it mentions faster growth rates being linked to higher cancer rates; I also think it’s frightening, because it applies to me, and now that I have been presented these additional causes of cancer, I realize that there could be a higher risk for me than I’ve previously thought – of course, this is not meant to be hypochondriacal self-diagnosis but rather a smarter awareness.
