I have just completed another cycle of my homegrown therapy: 3 months castrate followed by 3 months with testosterone [T] > 1,000 ng/dL. The difference this time is that I was receiving radiation on L5 during the castrate phase.
The PSA during these cycles follow a familiar patern to me. PSA is very close to zero when I begin the T phase. During the third month of T, it rises 50% to ~37.
I didn't do monthly tests in this cycle. I wasn't sure how the radiation would affect them. But at the end of the third month of T, on2/29, my PSA was only 13.6.
Seems that almost two-thirds of my PSA was due to the L5 lesion. That still leaves the one-third, of course.
I have never produced much PSA. It was only 0.8 when a nodule was found. So the numbers above are big numbers for me.
My aim with radiation was to (a) treat the lesion before it became a major problem; (b) debulk the cancer; (c) discover the L5 contribution to my PSA number.
I shall now resume monthy PSA testing & discover how the lesion was affecting PSA doubling time.
I'm posting this as it might be of interest to anyone with a solitary bony met.
