I too was uninsured. Since I was not going to be disabled for over a year I could not get any assistance.
My hospital provided great treatment, now I am left with $70,000 in bills. Get treated if you can then worry about paying.
The drug companies gave me chemo for free. I make too much money for the hospital's foundation, but they offer help to some. Your MO should have a social worker that can help you fine what assistance is availible.
The only doc that will not see me is the ENT who wants cash up front.
