I have prostate cancer. But I am happy | George Monbiot

The principles that define a good life protect me from despair, despite this diagnosis and the grisly operation I now face

It came, as these things often do, like a gunshot on a quiet street: shocking and disorienting. In early December, my urine turned brown. The following day I felt feverish and found it hard to pee. I soon realised I had a urinary tract infection. It was unpleasant, but seemed to be no big deal. Now I know that it might have saved my life.

The doctor told me this infection was unusual in a man of my age, and hinted at an underlying condition. So I had a blood test, which revealed that my prostate-specific antigen (PSA) levels were off the scale. An MRI scan and a mortifying biopsy confirmed my suspicions. Prostate cancer: all the smart young men have it this season.
