The CT scan showed that some of my affected lymph nodes had increase in size, but very little (like 1 mm). The others were the same size as a year ago.
So, no treatment! Blood tests every 3 months, and a CT again in August 2023.
No news on my PSA--I assume it's still less than 0.1. I'll check again next year.
Heart palpitations (premature ventricular contractions, or PVCs) are still a nuisance. That may be my next intervention.
That's all for now--stay cool!
