My mother completed her RADs in the first week of June. Recently she has been in so much pain. A scan was done last week and the Oncologist didn't want to discuss it yet because it showed not clear . He thinks because of the type of surgery she had it could be a false positive. Now a MRI is being done this coming Wednesday to get a better picture of whats going on. Her pain is in all the same spots. Her ear ,tongue ,and rear jaw bone that was left in after surgery. My question is Could the cancer be relapsing so soon. Its only been 3 months . Also her neck is so swollen in the morning . The Oncologist said it is from the lymp node removal . About how long until this swellen clears up
