Hi,
I stopped getting the DRE exam for two reasons. First and foremost, I undergo a 3T mp-MRI every year, and my urologist feels that the DRE is the least sensitive of all the exams (including the PSA test). Second, after I underwent the TURP which led to the diagnosis of cancer, the surgeon I consulted afterwards found my prostate to be firm on one side after a DRE and sent me to be examined with an MRI. I searched the internet for a possible effect the TURP might have on the prostate and, sure enough, I found that a previous surgery would compromise the prostate in any DRE exam.
