@chipe Best wishes! The radiation oncologists showed us the virtual images of the PSMA scan at the visits. I just sat there and was in awe of medical advancement. I'm thankful for this scan because in my husband's case, it can at least pinpoint where the recurrence is. However, like many other people here mentioned, the oncologists said that smaller recurrence (less than 2.5mm or even some that are about 0.5 mm) will not appear on the scan. I feel that this is like playing hide-and-seek game with these microscopic cancer cells. Definitely, it's more complicated to make decision on the most suitable treatment for patients, like my husband.
