My dad had a PSA of 10,000+ when 1st diagnosed approx mid august. After 2 chemo sessions down to 1146. Blood test just before 3rd round of chemo (I peaked at notes was not told) down to 714.6. I know this is way wat too high but this must be a good sign yes?. I make that after two chemo sessions approx 90% reduction, and day before 3rd round of chemo approx another 37% reduction (1146 to 714.6). He is now half way through 6 rounds of chemo. The cancer is in bones as well my question is, will the cancer that as spread be the same type/strain that came from prostate?. (original source). I wanted to know because my hope is that if PSA is getting lower the prostate must be shrinking yes?. And my hope is that the chemo is having the same effect in the bones. But last few days dad is feeling unwell I just hope this is side effects of chemo. He feels tired I know this to be a side effect, but very sore lower back burning pain in legs. I just hope the cancer in his lower spine is not growing again, he had radiotherapy on it 2 months ago.
Cheers for anyone's time reading or replying to my post.
