In a New York Times article on the uneven quality of medical care for cancer patients, there was a mention of racism:

Race and ethnicity come into play in ways that are not understood. A study published last year in the Journal of Clinical Oncology by Dr. Bickell and other researchers assessed how likely a woman who had surgery for breast cancer was to miss out on other needed treatments — drugs or radiation — at several high-quality teaching hospitals. If she was white, she had a 1 in 6 chance of failing to receive the treatment; black, 1 in 3; and Hispanic, 1 in 4.

A second study published last month by the same group suggested that breakdowns in communication played a part: a third who did not receive the recommended treatment had refused it, and another third missed out because of “system failures,” meaning it was recommended but, for some reason, never happened (and in another third, doctors ruled out the treatment for medical reasons).
