When my husband was diagnosed with laryngeal cancer, after all the testing, radiation and chemo started almost 6 weeks later. He underwent 35 radiation and 2 chemo treatments from August to October 2010. Then in February 2011, he had to have a trach and they did another biopsy. In late March 2011 he had a complete laryngectomy, neck dissection and throat reconstruction. The PET scan in later November showed no signs of cancer. Our specialist said that it was hiding behind the swelling. We were also told that most have radiation and chemo first and after researching this, we found out it was true. It all depends on if it has spread and how large the tumor is.
He was lucky. There was no spread to lymph nodes but the tumor was large. It generally takes several weeks for testing, biopsy, etc. before treatment is started. Be sure you have someone who has dealt with this type of cancer. Same goes for the surgery. You need someone that has done this surgery and knows what they are doing. We were lucky because our local ENT referred us to Emory Winship Cancer Center because he didn't do the surgery. Said we needed someone who specializes in this surgery because there could be more needed to be done, which in my husband's case turned out to be true.
Wishing the best -- Sharon
