I've got my results back. Now 4.5 years since RT. My PSA is 1.2, which is exactly the same result as I had six months ago in April. My post-RT results have been:
2.0: Oct 19
1.4: Apr 20
1.5: Oct 20
1.5: Mar 21
1.2: Oct 21
1.3: Jan 22
1.2: Apr 22
1.0: Oct 22
1.2: Apr 23
1.2: Oct 23
Huge, huge weight off my mind. Waiting for test results seems to get more and more stressful every time, and each test I work myself up into a panic and convince myself that this is the time that it's going to show recurrence. Stupid, but it's just the way I am.
This calls for a refreshing cup of tea to celebrate. Now I can put it out of my mind for another six months.
