My PSA has zigzagged slowly upward for many months. In October, it jumped up more than prior, from 0.7 to 1.0. Of course this is a low value, but we watch both the value and the pattern. Today, it measured 0.9
! I'd be happier if it was lower, but this is provisionally encouraging.
It was not supposed to be checked until January. But, I figured if it was in fact higher again, that any scans required would cost me less if done in this insurance calendar year. So, we checked it today.
For over a year, 3/2017 to 7/2018, the PSA was fairly steady, at 0.7 +/- 0.1, quarter after quarter, every 3 months. But in October 2018 its jump to 1.0 was unexpected, and gave me a little concern.
Enjoying math as i do, I played around with a similar zig-zag trend going forward to see what the underlying doubling rate might be. As it turns out, assuming the pattern continues in a similar manner, the doubling time is almost 5 years. I'll be happy to let it ride at that rate, and wouldn't consider any further treatment unless that somehow really kicked up. It looks evident that there is a very slow rise, but it's so slow it's not going to matter.
It's a good day!
