I went to my oncologist today to discuss the results of my recent CT scan. All lymph nodes are clear but there is a question of some thickening of my neck (internally) that has them concerned. I've been referred to my oncology surgeon for an endoscopy but it will probably take a couple weeks to get that done. Does anyone have any idea what this "thickening" may indicate? My oncologist said it could just be the way I am healing from radiation (that ended in the middle of August of this year)? How concerned should I be? Thanks for any input.
