Hi. There is another chemo drug they can offer if the risk from the cisplatin is too great. Our Cancer Centre here in BC did not offer it. Those with hearing loss before treatment should really be aware. My husband’s tonsil/base of tongue cancer was HPV+. He received only radiation as his treatment plan. He declined the chemo offered. His PET scan is early April. I will post the outcome. He managed fine with the radiation. Not a cake walk by any means, but he followed all the recommendations from his team. The SLP was very important and the exercises given were a blessing. His RD watched his weight, and he got through without a feeding tube. Magic Mouthwash helped significantly, and moisturizing the neck was very important. Mentally, I believe all cancer diagnosis are difficult for the patient and the caregiver/spouse and family. During this period in society, where a lot of visits are virtual and without human touch, it made things more difficult and were dearly missed. I wish you and your dad well!
