Dr. Greene's Answer
What a tough time for the family!
Most tumors in kids come from a combination of genetic susceptibility and some kind of environmental insult. Not all susceptible kids get cancer, and not all kids exposed to toxins get cancer. However those kids who have both, often do. The list of possible environmental toxins is long. The chemical plants are one possibility. If there is an environmental medicine doctor in the area, a consultation might prove a very wise idea. Most cities now have good doctors in the field. The American Academy of Environmental Medicine, for example, has information on finding a doctor with experience in environmental medicine at www.aaemonline.org.
