Saagar,
Everyone's experience with OC is different. Here is a link to learn more about your type of cancer
http://www.oralcancerfoundation.org/facts/rare/mc/index.htmthat's a good place to start. From what I've read prognosis' are usually good on low grade and not so good on high grade...but those are just numbers, it doesn't mean squat to you as who knows how your body will deal?
Don't get too worried, just because you were diagnosed with cancer doesn't mean it's the end of the world. Get the absolute best care available as you may only get one chance at it.
Best of luck, Be well
Eric
