Read the paragraph. I have been a nurse for twenty years. In that time, I have seen a great number of patients suffer because they did not have health insurance. One of the worst cases was a young mother of two who was diagnosed with early stage skin cancer. Because she could not afford treatment, the cancer spread from her skin to other parts of her body. By the time I saw her for the first time, the cancer had reached her brain and she could no longer be helped. This sort of thing should not happen to anyone. A strong universal health care system could prevent instances like this from occurring.
