It is my understanding they might not know what cancer it is until after biopsy results come in. I don't know much about clinical trials. The few I checked into I was not a candidate. I hope I can continue with the fulfirini. I know how to deal with the side effects and am used to the routine. I had a chest X-Ray today and my lungs are clear. They were also clear on a recent CT scan. My liver is also good and the pancreas was stable. My hope the cancer is a metastasis and the chemo I am on can control it. I appreciate your time and care in answering me. I feel like I have been on a roller coaster of hope and disappointment since I was first diagnosed back in March of 2022. All in all though I have managed to stay active and enjoy life the best I can. Living in the moment, but still having something to accomplish when I get out of bed in the morning has kept me sane. I also use cannabis which helps tremendously with anxiety. Pain and appetite. Thank you for your best wishes.
