What you need to do is to discuss their with your Dr who can work with you to to a risk benefit analysis so you can decide. Or maybe contact your local health Dept which keeps records of air quality where you live. What you feed u & son is likely a greater risk for many cancers. Go to american cancer society& learn more. Do not search Dr Google. Consider paying 4 uptodate.com & learn more.

The risk for Leukemia in the situation you are in is a debatable issue. it is certainly not a proven fact. So I would not rush to relocate away from a main road/ freeway. You can do some more reading to reassure yourself that thousands of people have their residence close to large roads/Freeways. Other than the expected noise and excess of emissions, there is no proven risk for developing Leukemia
