Don’t forget that Finasteride works by shrinking the prostate. However, by shrinking your prostate, one of the side-effects is that your PSA is artificially reduced by the same percentage.

If your PSA was 16, if (hypothetically) Finasteride reduced your prostate by 50%, then for a PSA of 8, you have to multiply it by 2 to get the corrected PSA (of 16). That may have happened to you, such that your next PSA of 10 was an artificial number due to the Finasteride that you then have to multiply by 2 to get the corrected PSA (of 20); and your recent PSA of 11 is actually 22.

(That happened to me. When my PSA hit 5.0, I started on Finasteride (due to urinary issues). My next PSA (6 months later) was 2.7. But, I knew to double that to get my corrected (true) PSA number of 5.4.)

If this is what’s going on with you, then your medical team may have to take a closer look to see what’s really going on.

With that elevated of a PSA, if it were me I would request PSA tests every 4-6 months.
