@rockin2047, it looks like you've had a chance to see the results of your MRI on the patient portal before being able to discuss them with your cancer team. While fellow members can explain some of the terms or you can Google them, remember that the result of the MRI is only one piece of the diagnostic process. Your cancer team will put all the pieces together to give you a proper diagnosis.

I think you'll find this related discussion that @gefears42 started a few days ago to be reassuring and helpful. He, too, is going through this process at the same time.

From what you shared in the other discussion you started,
- Prostate transrectal biopsy https://connect.mayoclinic.org/discussion/prostate-transrectal-biopsy/

The MRI suggest a small lesion with a high probability of cancer and a second one thought to be benign. This MRI will help guide the biopsy you're having this week. I will be thinking of you.
