It's clear that the message we're supposed to get is that racial discrimination leads to a higher risk of breast cancer.

It is most likely that if one had the data to drill down to root causes, one would find that both factors are the result of correlated behavior patterns (diet, appearance, demeanor) tied to where people live and the groups they identify with.

It's clear that the message we're supposed to get is that racial discrimination leads to a higher risk of breast cancer.

Yes that is the message we're supposed to get but the simple fact is that this study did not attempt to measure racial discrimination. It attempted to measure the *perception* of racial discrimination. The latter often exists without the former.
