Based on these categories, we can tell you that these research results do not tell us much. They just suggest there is an association between environmental factors and childhood cancers, but the most results are inconclusive or inconsistent. They also suggest that research needs to continue to know more, because we know very little.

Some others studied only the young children but not the older ones.
We need to investigate environmental factors globally with a wider participation in order to:
