Newly diagnosed prostate cancer

The tissue removed in a TURP is from the transitional zone around the urethra and is done to remove inward pressure on the urethra that is impeding urine flow and causing urinary symptoms. The majority of prostate cancer lesions form in the outer cortex of the prostate, so many times PCa is missed in a TURP. You are "lucky" in the sense your cancer was found. Unfortunately, the answer to your question is no, all the cancer is likely not removed in a TURP (otherwise we'd all have TURPs for prostate cancer, keep our prostates, and pee like pros.)

I would think your uro would want a biopsy -- after a healing period from your TURP-- to asses the quantity of G7 (3+4). Usually having more than one biopsy core of G7 (3+4) means you are not an ideal candidate for active surveillance (AS). It's also possible that a biopsy will find lesions that are a higher grade than G7 (3+4). IMO it may be too soon to rule in AS as a wise choice.

Imaging such as an MRI can suggest whether cancer has grown out of the prostate locally and whether there are enlarged lymph nodes, suggestive of metastases. A mpMRI, which is more sophisticated, can identify suspicious areas in the prostate, each of which the radiologist grades on a 1 to 5 scale, where 1 is unlikely to be clinically significant cancer, and 5 is very likely. The mpMRI can be used in a fusion biopsy which ensures tissue samples are taken from these areas in addition to random cores throughout the prostate.

I suggest you take this waiting time to read up on primary treatments for prostate cancer, which include surgery and various types of radiation.

You've got some advice upthread and it sounds like you have a good plan going forward. G7 (3+4) is considered a favorable intermediate diagnosis--if it turns out you need to treat (which I'd guess is likely) most treatments will do the trick. Good luck as you go through this and let us know if we can help!

Musicman, you’ve gotten good advice and comments above, nothing to add, just a welcome to the forum, lots of knowledgeable people here as you can see.
Get the biopsy, get educated, and then get educated again, before making any decisions.

Thank you all for your comments and advise. I have been looking at various web sites, such as Johns Hopkins, Harvard, Mayo, Cleveland Clinic, and feel that I have learned much. I have a couple of friends who have been through this and come out successfully the other side - both several years with undetectable PSA. I'm trying to stay optimistic, however, there are times I feel a bit overwhelmed. These usually pass fairly quickly.
