Do delays in diagnosing kids with various types of cancer have anything to do with the actual outcomes of each specific situation? New research concludes that there is very little evidence to connect early pediatric cancer diagnosis with what impacts eventually happen in these kids. Once malignancies happen, they expand more rapidly in kids than adults.

Until there are clear answers (if ever), what can parents do to try and quash the environmental contributors to cancer? Staying away from carcinogens, cancer-causing and processed foods, food additives and other dangerous items is a great start -- but it's a very hard one.

Unless you live an extremely healthy and organic lifestyle in a mud house on a mountaintop, you're going to be exposed to cancer-causing agents all the time (hopefully in small amounts).

If there is a silver lining here, it's that cancer in children is rare -- affecting about 10,000 kids in the U.S. annually. Still, that is no comfort to parents with children afflicted by cancer.
