[quote]So in your opinion this would be considered catching it early? Does that matter with this type of cancer? [/quote]
Yes, you've caught it early. And yes, it matters.
I'm certainly not saying that you will need no more treatment -- that decision will depend on further tests and your doctor's recommendations, and you'll want to take whatever you hear in your second opinion into consideration as well. But it is far better to have caught this at the earliest possible stage of cancer (in situ) rather than giving it an opportunity to spread.
If you haven't started doing so already, take a look at the main pages on the
Oral Cancer Foundation website -- there's a lot of information there that will help you learn more.
