shared culture and poor women's chemo

Researchers found that doctors were more likely to reduce the chemotherapy dose for heavier patients and those who were less educated, and lived in zip codes with lower median household income and higher levels of poverty. Severely obese patients were four times more likely to receive a reduced dose, and women with less than a high school education were three times as likely to have a dose reduction.

maybe this that has something to do with why low income women have a lower survival rate of breast cancer.
