No defined lesion, is Cyber Knife possible

I finally got a copy of my 3T MRI report and as my urologist told me, the results showed "No MRI demonstation of any lesion in the prostate that is specifically suspicious for prostate carcinoma."

As posted below, my confirmational second biopsy showed two small areas (3 & 7%) of Gleason 3+4 whereas my original biopsy was one 10% core Gelason 3+3.

I haven't paniced yet, as I am having the slides reviewed and genomic testing done on the positive samples.  However, I am starting to consider my options in case future treatment is required.  I haven't had a consultation with a radiaton oncologist yet, but Cyber Knife treatment does sound like something I'd like to consider.  My question is, since there's no defined lesion to target, is Cyber Knife possible; can they just fry the whole damn prostate?

How can you write that there are no defined lesions? You have at least two areas that are worthy of treatment/attention.

The radiologist's report said there were no lesions that showed on the MRI.  Just quoting verbatum from his report.

Typically, the biopsy report rules. The MRI just didn't pick up the Gleason 3+4 cancers. Moreover, an MRI only identifies locations that could be cancerous. One then has to follow up with a biopsy.

I think we're going in the same direction.  I agree that I have two lesions.  By saying no defined lesions, there isn't anything showing on the MRI that could be defined by fiducials that could be targeted by Cyber Knife.  I didn't know if that was a necessary criteria for CK treatment.  I now know it isn't.

hopeful and opt...

The total prostate is treated; also the radiologist has the ability to expand the perimeter beyond the prostate when it is suspected that the cancer has escaped the prostate, which I do not believe is your case.

I suggest that you may wish to explore doing the same as I did, which I mentioned in your  last thread before receiving active treatment

I am considering that.  The GPS from the Oncotype testing will have a strong influence on my decision.
