From a reader:

Jonah,
I’m a cancer survivor who was diagnosed in Germany. After two months in
the limbo that is Germany’s national health care system, I realized it
would probably kill me so I returned to the U.S. for treatment. My
chemotherapy started on the same day I saw my oncologist in New Jersey.
Eleven years later and I’m still here. I wonder what the survival rates
are in the UK?
