If the doctor did a 20 core sample, then you should have a biopsy that shows each core and the result.

You say 3+4, but you don’t say how many were found. The information you supplied is not enough to really know what happened in the biopsy.

You include a 2023 biopsy that apparently found nothing.

Can you locate the biopsy report with all 20 cores listed in 2026?

If you have a single 3+4 you might even go into active surveillance if it has a low percentage of four. Another thing that would be useful to find out from the biopsy.
