When my laryngeal chondrosarcoma (less than 200 cases ever) was diagnosed the first opinion I received from one of the top 10 surgeons in this area was that I may end up with a permanent trach and maybe a feeding tube. I ended up visiting 5 other surgeons and Mayo was the only place that provided me with hope that they could remove all the cancer and maintain the majority of functionality. I strongly advise you to seek additional opinions and Mayo should be at the top of that list.
