My 49 yr. old sister had surgery May 7 at MDA/Houston for cancer on her upper palate. She finished radiation on Aug. 9 and it still quite ill from it all. Most recently she acquired an infection which has affected her mouth, eyes and ears. Treatment has been antibiotics, steroids, eyedrops and eye washes, plugs in her tear ducts and I can't remember what else. The results of her recent ct scan show "something" which has scared us to pieces thinking that the cancer has returned. From what I've read here today it could possibly be scar tissue or swelling caused from the radiation. She has another scan scheduled for next week. What does a second scan mean?? Is this followed up with a biopsy?? What are the chances it is only radiation-damage that is showing on the scan?? Guess what I am asking is, is it more likely it is cancer showing up? We are all very frightened. Thank you. Tammy W.
