Newly diagnosed with prostate cancer and still gathering information

Hello - I am surprised that with a 4.1 ng/ml PSA, that you are at a 4+3=7 Gleason score with 13 out of 15 cores positive (that is a LOT of cores...it is usually a 12 core biopsy at most). Suggestions:
1) If your urologist did not order the test, MAKE SURE they order the "Decipher Test". It is a test that screens for 22 prostate-cancer-specific genes and mutations that help determine short and long term rate and risk of progression/reoccurence, as well as your predicted longevity.
2) With what is already a 4+3=7 Gleason score (not the slightly more preferable 3+4=7), I'd go straight for DaVinci Robotic-Assisted Radical Prostatectomy. "Why wait?" Like my doctor told me even being a 3+4=7, and after I asked what my options were including "Active Surveillance", he said: "You're already at a moderate risk level, why would you want to do Active Surveillance?...the cancer is there, it is only going to continue to grow and spread..it is NOT going to go away." Then without a pause he said: "I'm taking your prostate." I'm glad he did because my pathology was much worse than what the 3+4=7 Gleason score might have suggested (my PSA was slightly higher at 6.1 ng/ml). My urologist changed his overly confident mindset of "you'll be alive in 15 years", to one of my "cancer is an aggressive one...we need to talk about radiation (after the RP)."
3) The PET Scan is quick and easy - 30 minutes of slow incremental scanning of your body from neck down to mid-thigh looking for any Gallium 68 uptake that may be elsewhere in your body. What you want is that all the uptake was/is confined to the prostate, showing that the cancer has not spread to other areas (metastasis). I was lucky, my was all confined to the prostate, but that is all the PET Scan tells you. It tells you nothing of pathology.
4) Make sure that your urologist has done a couple thousand DaVinci RP's, and that you are having it done at a highly regarded hospital, preferably a teaching institution like a university medical center (U of A)...NOT your local community hospital. Actually, most local community hospitals can't cost-justify having a DaVinci Robotic system...you will only find them in 300-400 "+" bed hospitals that see a LOT of patients. BTW...the DaVinci method is preferred by most urologists because it is a single, 2.5" incision about 3 inches below your navel, instead of "five" 3/4" incisions all around your lower abdomen with the traditional/older method. You just want "best practices", "best technology", and "best urologist" in your region.
The main takeaway is that a Gleason Score is only the tip of the iceberg that tells you have prostate cancer and to what "preliminary" extent. If there is one thing I have learned through my own case and reading many other accounts here - like yours - is that the Gleason Score and a PSA that is only 4.1 ng/ml can fool you into thinking your cancer is not aggressive or aggressive "yet", when in fact, it could already be quite aggressive.
Good luck with everything.

I was a 4.01 with a Gleason score of 4+3=7, 13 out of 15 cores positive with cribriform. 2 weeks post surgery.

I'm 60 and I'm scared as well. I'm having some anxiety about my surgery but I know it's necessary. I don't want the incontinence afterward and I'm going to do the necessary PT exercises etc to regain control of my bladder. Your Dr. might have wanted to schedule surgery that quickly due to the fact that it's a process with insurance etc. and takes a while. They might have wanted to schedule it in advance so that you could get a spot quicker etc. and more from a logistic standpoint then a disease standpoint. I wish that I could get my surgery quicker, but I'm stuck with my date due to the number of people in line ahead of me for the same surgery.

My thought. precisely -- I have seen and read my recent MRI and clearly have a focal lesion. But it is contained within the prostate. I see my urologist in the morning to go over the results and make a plan. I will push for treatment ASAP. No AS. I would prefer to bypass a biopsy. Just remove the prostate and send it on to the pathologist. Can have the whole thing, never mind "cores"!

My insurance company denied my decipher test as medically unnecessary! *• I am 4+3 so I’m getting it either way and will fight with insurance to pay it.
