Some pollutants could add to damage caused by other environmental factors. However, not everyone would be as likely to develop cancer from that set of environmental factors. Because there could be many combinations of environmental and genetic factors, enumerating all sets is impossible. We will end up tracking the most common sets of factors first, only tracking other sets once the common sets are known and have treatments. We can’t catch them all unfortunately.
