If you look at the rates for cancer in children in Canada over time, you do not see an upward increase. However, if you look at much larger populations in the European Union and the United States, there is a 30-year upward trend in cancer in children. There are the same kinds of cancers in children in Canada as in other industrialized countries. Whether the fact that we don't have an increasing trend is just a matter of a rare disease in a small population or whether we simply don't have an upward increase, you can't tell with the numbers.
