This post explains why it is so important to get a second opinion from a comprehensive cancer center, where the staff deals only with head and neck cancer (so they have seen it all) and takes a team approach to treatment, bringing the knowledge of a variety of specialties to each case.

Another resource for information about treatment facilities, in addition to the link DavidCPA provided, is the National Comprehensive Cancer Network, an alliance of 21 leading U.S. cancer centers that annually publishes state-of-the-art treatment guidelines.
