If she made no effort to be retested, if this goes to court it should be thrown out.
Tests are not perfect for almost all medical conditions, and common sense tells you to retest.
These kind of lawsuits are drivers of high medical costs. Poor substitute for personal responsibility.
I agree on the point about raising the costs of medical care. But she did go back (I think to the same place) and they told her she was terminal. They scared the poor woman half to death and she started planning her own suicide.
Keep in mind, she is a Columbian native, and English is her send language. She probably doesn’t have much money — she and her husband both work at low paying jobs and likely don’t have insurance. She also may not know how to “work the system” to get what she needed (a 2nd opinion) and was frightened. After all, she went to this place to get the mamogram because it was advertised as “cheap”.
