Hello Perkij,
My experience of treatment is somewhat historic, my "Journey" began in March 2013.
I was told then that ideally you would have an MRI first, and then a biopsy. If you had the biopsy first the prostate would need time to recover from being treated like an archery target so as not too distort the gland and mess about with the MRI imaging. Subsequently I learned that reading the MRI is a bit of a dark art, depending on who is looking, and at what. It alone is not in any way conclusive of anything, good or bad.
Your initial biopsy sounds like a general "stab in the dark", and see what comes up? Are you about to have a targeted biopsy?
Bear in mind that the only way to ascertain what is going on and how affected you are/were is when the gland is in a dish in a lab being sliced up by a technician.
FWIW I don't believe cost comes into it so much with PCa, not so much anyway, as it might do with other areas of health.
