I am being treated for prostate cancer with radiation and hormone shots. My question is the treatm?

I can relate. The first three months of ADT left me feeling as you describe, especially in the first few days after each shot. So I talked it over with the medical team, and they promptly switched to Lupron. Rather than a monthly shot in the belly, which was painful and annoying, Lupron is every three months in the upper buttock. That’s advantage No 1. Advantage No 2 is that it doesn’t knock me out, and I can go about my daily routine more or less as normal. I’m over 80, so I deal with various aches and pains; sciatica kicks my ass, so to speak, especially at night. Lupron makes it all a bit worse, but I’m trying a little Valium at night and Tylenol during the day. This is supposed to continue for another 18 months, along with weight gain and “cognitive decline” — just what I need, right?
But here we come to Advantage No. 3 — I’m still alive and likely to remain so, unlike my friend since high school who died a miserable, painful death from metastatic prostate cancer a few years ago. In May they told me mine was stage 4 and at the top of the Gleason scale. Localised, thank god. After high-intensity short-course radiation, it’s gone. ADT will help to ensure it doesn’t come back. If that means a few aches and pains, I’ll take it. And if I get dumber quicker, I’ll take that too. I give thanks for great science and the grace to live another day. Be well, and try not to be crabby to the people who love you. (And if you are, you can always blame the drug!)
