I had radiation therapy for prostate cancer 10 years ago. since i've had psa tests yearly. the last three years the psa has risen 0.1, 0.4, 0.5. does th?

Prostate cancer: A small percent of rad treated pts will recur even this late. A urological eval is warranted. At your age that small amount of psa elevation should not affect your longevity..

Rising PSA&CA: I have followed many pts for nearly 20 years now after rt for prostate cancer. I definitely see a rise in the psa at about 8 years and again at 13 years. After each of these rises the psa levels off again and does not continue to climb exponentially. I have worked many a man up with lots of bone scans and cat scans and always find normal results.

At 85, very unlikely: Congratulate you for paddling alone well in coping with prostate cancer after radiation. Now you have rising PSA after definite treatment which may happen up to 45-50% of so treated patients but is usually inconsequential for longevity and quality of life, but occasionally few. So, keep on annual or biannual PSA + DRE (digital rectal exam). Besides, it is worthwhile to follow alkaline phosphatase.
