I have just been reading research into the finances of US citizens. It is a massive piece of research, with few surprises. But I was surprised at how many people said they had put off a Drs visit because of money. Either because they had no insurance to cover it, or could not afford the co pay.
Now some of these visits would have been for routine things that were fine to put off. But some may have been for early indicators of illnesses such as cancer, and putting off a visit may have major consequences.
