I lived near 880 in Oakland and always had massive amounts of this super fine sticky dust. They call that 880 corridor cancer corridor. My friends who lived next door who I was renting from, their son got leukemia and they think that had something to do with it.

That sounds like a really easy thing to study. (Does living near a highway significantly increase risk of cancer?) A single anecdote like that isn't very convincing.

Here's a study done from 1990 to 2010. It shows a statistically significant increase in cancer.
