Slowly approaching the "C" line on the asymptote. C as in cured.
A Johns Hopkins study showed that if you make it to 10 years with an undetectable PSA, your odds of having a recurrence in the next 10 years are 6%. And if you're unlucky enough to be in that 6%, your odds of developing metastatic cancer in that second 10 year window are still very small, and dying of it practically zero.
So I'm setting my sights on the 10 year mark, in 2017. I'll be 55.
