hii my father was diagnosed with GE junction cancer in may,2010. after diagnosis he went thru operation and then six cycles of chemo. on doing PET scan, it was found that cancer has spread to lungs, and near by spleen.and also near the esophagus. but on doing biopsy of the esophagal region, it shows ulcer. i want to know is it possible that inflammation in lungs and other parts are any other thing, not cancer. what is the prognosis in this case.
