Any increase in the incidence of cancer is due to a number of reasons included our increased longevity. The peak age range for being diagnosed with cancer is 85 - 89. As more people survive illnesses that previously killed people (infections, heart disease, tb etc etc] they end up living to an advance age when their bodies are less efficient and beginning to mal function and cancer is often a result of this malfunction
There are, and always have been contaminants in the atmosphere and life style choices that make some people more likely to get certain cancers, including young children.
