My 20 year old sister was diagnosed with squamous cell on the front side of the tongue. She had surgery to remove it and then 33 radiation treatments. They said it was completely gone. Four months later, it came back (t4) on the base of the tongue and it had metastisized to the lungs. There was no hope. Thank God, He did a miracle. After aggressive chemo. The cancer has reduced more than 70%. Now she is worried because she has constant heachaches. She also had a neck dissection of which that area has turned hard. Maybe scar tissue? Can you please tell me your side effects? How are you doing?
