But it seems like cancer is much more prevalent than it used to be and I wonder if modern inventions are at least part of the cause.
Of course cancer is diagnosed much more accurately than it was in the past. In the 1940s and 50s many of the people who died of "old age" might actually have had undiagnosed cancer. But it seems likely that the deteriorating air quality from pollution and the multiple preservatives and other chemicals routinely added to our food and medicines might at least be a negative influence that makes people more likely to get that disease.
I wonder if any scientific studies have been done on this topic.
