Thanks for your reply - hope you are doing well! In terms of the structural issues, I agree these are relevant. One question I have is how you feel differences in care coordination/access to multispecialty centers will lead to disparities patterned by race/ethnicity or SES. Is your assumption that patients of color and low SES patients will have lack of access to more coordinated services, even with the same insurance coverage? This brings me to my second thought, which is that, as we discussed in class, generally health care insurance coverage is considered separately from health CARE disparities. Not that differences in insurance don't matter, but that when talking about health care disparities you are drilling down a bit more on what makes people have different outcomes/be treated differently even with the same financial access to care.
I absolutely agree with your assessment of the possibility for biases and assumptions to influence treatment recommendations for cancer care. There have been some studies of this, including this one using standardized clinical vignettes, which showed an interaction between race and "social vulnerability":
