As you can tell from my signature line, I am one of the few that was diagnosed with mucoepidermoid carcinoma, had a maxillectomy, and now am learning to adjust to the obturator. I went to a cancer center, Brown Cancer Center in Louisville, KY. I had a great team and the decision regarding radiation was determined by the grade of cancer, which was determined from the final pathology report after surgery. The report stated that it was a HIGH GRADE and close to the margins. Although they felt that they had gotten it all, radiation was no longer an option. Yes, radiation was not a walk in the park, but they were able to adjust the field as needed to reduce as much adverse effects as possible. Has the Dr. indicated the "grade"? I will be happy to answer any questions that I can, there are two others on the forum that I was able to communicate with while I was fumbling my way through this.
