Marie,
I wish you luck as well. This is a challenging cancer. I was diagnosed at Stage 3. My biopsy pre surgery was inconclusive as they could not get a good sample. I agreed to have the tumor removed as the surgeon assured me that it was in a good spot for removal and he was 75% confident that it was non cancerous. The morning after surgery he stopped by quickly to say that the margins were clean. That left me feeling hopeful until 5 days later when I received the pathology report. I was shocked to learn that I was Stage 3. I had minimal symptoms leading up to my diagnosis. I very slight feeling on my left side that I attributed to a muscle pull. My genetics indicated KRAS as well. I'm being treated at Mass General Boston. As much as I'm not looking forward to taking the 5FU with radiation, I figured I'm all in at this point. I've been reassured that it won't be as bad as 12 cycles of Folfirinox. The Oxaliplatin is torture. They eliminated it for the last two cycles as my neuropathy had worsened. Hoping that it's not permanent. Again, all the best to you in your journey. Steve
