Cisplatin & radiation is a common "One, two punch!" Kept me from another surgery and literally saved my life! Lost a lot of hearing (Especially high pitches) from cispatin so ask questions about that but the trade off is worth it (I'm still breathing). They will tell you that once you have the symptoms they describe the damage is done and hearing will be affected. Kathy is correct, eat like a beast now! I had a port and a PEG prior to starting treatment. That feeding tube became my best friend for a while so don't let his ego prevent getting it. Port makes hydration easier with cisplatin treatments so I'm sure it will be recommended. A few years from now it'll be a memory in the rear view mirror. Hang in there & Best Wishes!
