Hi JoAnne. My name is Jim. I've had barretts esophagus for three years now. Barretts is a pre-cancerous condition where the cells have changed. In my case, from gastric reflux disease. I had an open fundoplication surgery performed in Oct. 1999. I still take meds. for acid. They took my stomach and wrapped my esophagus to help prevent acid reflux. I have an EGD every year to determine if dysplaia is present. It is my understanding that dysplasia is the onset of the cancer. I am still negative at this time. They tell me that the pre-cancerous cells aren't proof positive that you will develope cancer, but it does increase your chances. I am currently looking into photodynamic therapy if and when the dysplasia occurs. There are many avenues of information to explore. I am in no way an expert. Just someone trying to live with this problem. If you want to ask any questions at all, please feel free. I hope your dad does get good news and please remember, there are quite a few treatments for this problem. I don't know all of them, but I'm not giving up. If you need to ask anything, you can contact me at Medjbr@aol.com.
