My husband was diagnosed in 2017, with PSA 48.74 Gleason 8 (3+5), I think Stage T2a. We were told it was not operable, so he completed 42 rounds of direct radiation and then started Lupron shots every three months, the last dose was in September 2021 I think. All this brought PSA down to <0.06 but yesterday we learned PSA has risen to 0.10 and the doctor said he's "worried" about it. He wants to see my husband in two months instead of four, and if PSA is still at o.10 or more, treatments will begin anew with Lupron and a pill added to that shot.
My husband is in a high-risk category, as best we can determine, he's the fourth-generation male in his family to have PC. We had his father in the house with us for his last four months, and my husband watched his dad die from PC complications.
I need to understand how such a tiny increase in PSA would make an oncologist "worried" about a patient, my husband is convinced he's dying within a couple of years. Does such an incremental rise truly indicate the cancer is trying to "come back"? Thanks in advance for any knowledge y'all can share with me.
