A close relative of mine (who is single) also had cancer and had 100% of it paid for.
Transportation costs are also paid for, although we never needed overnight accommodation so far.
My prior experience was in Australia was a youngster under a particularly terrible universal care system in the 1989s, and then in the 2000s when I lived in Canada.
I get a little weary of the refrain about how American healthcare is terrible, esp. for poorer people - it’s actually very good.
