That is so scary, when a patient is fighting for her life, that she also has to deal with insurance companies who won't agree with the decisions of a trained oncologist. She's been paying insurance premiums exactly for the reason of getting life-saving treatment, after all.
It is. Why are they allowed to even do this? That's why we need single payer. People can still get insurance,but they have to realize insurance companies are not above doing dirty deeds like this for grins and giggles. This is what happens when foxes get to guard the henhouse.
