Unfortunately I am not familiar with this type of cancer. My cancer was removed surgically and did not require chemo or radiation. Mine was a very rare form and less than 200 case had ever been reported of laryngeal chondrosarcoma. What I do know is that of all the doctors I went to get opinions only one believed that he could get all the cancer and maintain my functionality; breathing, speaking and eating. Mayo is the only place I found hope and I believed they could help me and I had faith in my doctor. If you are being treated at Mayo you most likely have the best care anyone can provide. My thoughts and prayers are with you in your journey.
