To everyone, thank you so much. I have more info, but still a bit frustrated with the doc and hospital.
He had a TRUS biopsy on 4/13/21. From the sounds of it, there was inflammation (hemorrhoids) and it was difficult for my father to tolerate under local anesthesia. Because of this, the doctor said the 3 months is to allow for inflammation to go down at which time another TRUS biopsy will be performed under general anesthesia. One line the doctor emailed perplexes me "Not much benefit from doing mri since cannot tolerate another biopsy under local anesthesia." To me, this sounds like the doctor is trying to say what Old Barry said above, that it takes 6 or so weeks to heal after a biopsy before a good MRI can be done. I wasn't aware there's anything to "tolerate" for an MRI because it's non-invasive imaging. The doctor also mentioned that he performed a digital rectal exam which was normal. We are still trying to access the Pathology Report from the biopsy, the medical record system is so terrible and we're dealing with the hospital system's IT department now. Just ridiculous.
New questions:
1) Given this, a delay in MRI for healing makes sense right?
2) Should we insist on a transperineal biopsy?
3) Should we insist on an MRI at the same time as the next biopsy?
I know there were posts above about the US vs UK and insurance situation. Here in the US, my father is on what's called an HMO (Health Maintenance Organization). Basically we have, uninsured, HMO, and PPO (without getting into Medicare/Medicade). HMO is your run of the mill basic insurance where everything is low cost and just one notch above uninsured. I'm also on HMO but press for certain things so it's never been a problem for me. Sounds like I need to start getting more involved in my father's care, he definitely needs coaching. It's just tough because it's a day's drive to his place and doctors here do not allow mobile phones during an appointment.
I'll report back if/when we can get his full biopsy report. Thank you everyone.
