Surgery tomorrow

I've had a rather large mucocele for over a month. When I first got it, I drained it and it came back a few days later. I scheduled an appt. with a doctor and scheduled a surgery for tomorrow. At the time it was 1cm. Well, in the next few days it grew even more. Well, as I ate dinner, I accidentally bit it. It drained and bled, but has not formed a new lump. (It's been two days since that happened) Well, though there's no large lump, I can see that one is forming. There is also a small white bump. I can see that my saliva is still draining (very slowly from the front of my lip), which is why I suspect a large lump hasn't formed yet. My big question though is will the Dr still be able to remove the damaged gland, etc. even though I no longer have a large lump? I know it's only a matter of time for it to come back, and I'd rather do it tomorrow since it's scheduled and all. 

Thanks for any input!
