What would happen if I got cancer and didn't have insurance?

Say I worked a shitty job. Like the guy who makes your food at restaurants. Odds are good that they are the uninsured and you probably interact with them everyday. What if the guy who just took your order gets cancer?

People say that the ER will treat you if you can’t pay. But what about long term treatments like rounds of chemo or weekly use of a dialysis machine? Will the ER tell you to fuck off and die or do they still need to treat you?
