Boston,
It's always best to check with your doctor, but the same thing happened to Richard. It took several weeks after treatment before Richard's node completely shrunk away. The MO and the Head&Neck surgeon both predicted that the node would continue to shrink after treatment was completed and that's what has happened. The RO was concerned after the 2nd Cisplatin dose that the node wasn't shrinking more, so she insisted that Richard be switched to the Ebitux.
Today we saw the HEAD&NECK surgeon and she is very pleased with his progress. After the exam, she said that everything looked excellent. Tomorrow, he has an appointment with the RO and she will order the Pet Scan and whatever other tests to be done. We will be on pins& needles until we get the results, but the doctor commented today that the cancer was very small and she expected that the treatment was a success. I won't rest easy until we get the "all clear" report and we will probably always have that bit of unease about a reoccurrence. Take care...Geri
