I'm not a doctor yet I have researched cribriform pattern 4 extensively. While it is true that the vast majority of prostate cancers are slow growing and you can take time to research and decide your best options, other cell structures, like cribriform pattern 4, are agressive and time is important. I was diagnosed in mid-April with a Gleason 4+4, stage cT3a, and cribriform pattern 4. I had no symptoms, but by the time of my RARP on Monday, the PIRADS-5 tumor had grown to the point that urination was practical impossible. Additionally, during surgery, the surgeon found that the prostate had grown into the rectum, requiring disection of the prostate from the rectum. My surgery was over 6 hours. A colorectal surgeon was called in to scope the rectum and sutures were required to repair the rectum. We are waiting on pathology but obviously there could be cancer spread to the rectum and/or positive margins though I'm trying to remain positive. My point is, not all prostate cancer is slow growing and some, like cribriform pattern 4, can grow fast and lead to poor outcomes and mortality. My urologist said I had 3 weeks, not 3 months to start treatment. Find the best Dr. you can and listen to them.
