Thanks for your helpful response, Cheryl. My wife's surgery was on 2/5, stage 4, including a neck dissection, removing 35 lymph nodes, 6 cancerous. She has some swelling in her neck, which was expected. We started radiation on 3/20, chemo on 3/21. As of today, she is stable and proceeding with Mon-Fri radiations and weekly chemo for another 5 1/2 weeks. Our second chemo session with cisplatin is tomorrow, followed by a hearing test the next day. We have learned much on this forum from generous posters like you, which helps us understand and manage the side effects of this disease. Thanks again.
