I have a general question that isn't directly related to your discussion, but has to do with decision making regarding treatments. I am 78 years old, and have had progressive increases in annual PSA results over time - the most recent being 4.7. I went to a urologist and was told that I had to decide whether I should have an MRI to screen for cancer, or whether to even continue with having PSA blood work taken. It is likely, according to the doctor, that an MRI would indicate that I did have prostate cancer at my age and with the previous PSA tests. Even after having an MRI that was positive, I would then need to decide whether to have a biopsy or not.

My age has much to do with this, but I'm wondering whether I should decide to do nothing or have an MRI. I feel at least I should continue with PSA tests, perhaps every 6 months. Any thoughts?
