Yes. Cancer is an age-related disease, without a doubt. Average life expectancy is going up, so the absolute number of cancer cases is of course increasing. What one has to look at is the age-adjusted cancer rate, and the age-adjusted cancer rate is pretty well stable.
Some cancers have decreased. Stomach cancer has decreased dramatically. Some are stable, and others have slightly increased. The ones that are worrisome are prostate cancer and breast cancer, which, even age-adjusted, seem to show a slight increase, although not everyone agrees on that. There are also some childhood cancers that are increasing.
The question is, why is this happening? Is it because there are better detection techniques and now we are diagnosing these diseases where before we did not? Or is there something environmental going on? It's possible.
