PSA of 15 1 month after BPH

Hi everyone,

My dad had BPH around october 15th, he was taken to the hospital and had a catheter put in for about 3 weeks or so and was put on Avodart and Flomax. On approx. nov 15, he received a blood test and the results of the test, which we received yesterday (dec 7), show that he had a PSA of 15. His doctor wants to follow up in 6 weeks.

Could the high PSA still be as a result of the BPH? If it is cancer, why was the Avodart effective? I read it doesn't affect benign or malignant prostate cells.

Thanks everyone,
Mikey

Could the catheter also increase PSA from increased inflammation?

I had a catheter for several days and I wonder why they don't use a temporary catheter instead and teach patient how to use it. Seems like it would be less harmful.
