Thank you all for replying!!
As crazy as it may sound PSA went down a tiny bit of its own "volition"... but of course oncologist, excellent woman doctor, wants everything possible... new, different chemo, radiation so we'll se what happens. PSA is down from 74.8 to 66 which is of course irrelevant as this curse spread to the spine and broke vertebrae of lower back. We're at the hospital waiting for the CT staff since this morning to have him checked🪻🙏
