I was 1 of 2 people who had vocal cord cancer present itself in the manner it did.  The team at MGH was incredible.  Dr Clark does not follow the industry quick visits, however, he gives his patients as much time as they need; which means the next patient will need to wait, but it was and continues to be well worth it.  As of 11-15-2017 I am cancer free!
