with no health insurance do? The person makes too much for Medicaid and was working. . .thought that insurance was going to be continued. . .insurance company was sending correspondence that the person was a customer. Now, they have gone back canceling coverage even before the diagnosis.

Sorry to hear about this persons problem. Heatlh insurance and medical cost in this country has gotten seriousely out of control. It is shameful the insane greed the health care sector has been able to get away with.
As for your friend, they should worry about the bills if the opportunity presents itself. They should still be able to receive the same medical treatment, since it is a necessity. A public hospital can not turn someone away with a life threatening condition.

Well, usually they file for bankruptcy. Uninsured medical costs are the #1 reason for bankruptcy filings in the US.

Get the treatment now. Figure out how to pay for it later.

Get a lawyer, after John Edwards gets booted from the primary, get him to file a claim at the Insurance company.
