I'm sorry to hear. I had the skin metastases while waiting for surgery and treatment in less than a month after another cancer, and my 4th cancer in a year, so it was just added on. My cancer at that point was no longer in the lymph nodes, and roaming about. I had a radical neck dissection, pec flap, skin graft, Intraoperative Radiation (IORT) during surgery, followed by 5 weeks IMRT radiation, and chemo with taxotere, and Erbitux. My swallowing was fine, except during Chemoradiation, mainly from mucocitis, thrush

Maybe get another opinion. There is always hope!
