Mucocele (lip growth) removal in 1 yr old

DD developed a mucocele on her lower lip soon after birth. (A mucocele is basically sweling from a ruptured salivary gland duct) We waited and waited to see if it would resolve but it just keeps getting bigger. I told her pediatrician I wanted to wait until she was at least one to remove it, because I didn't want to interfere with breastfeeding. Well, now we have a consult next week with the oto clinic to decide what to do about it. It is benign and doesn't seem to bother her too much, but it keeps getting bigger and sometimes looks very sore. She has a tight frenulum and we'll probably go ahead and clip it at the same time we remove the mucocele.

The photos on the site below show the standard procedure for removal. *warning, a bit graphic* How might this kind of mouth trauma affect breastfeeding? Also, she will have to be put under for the procedure which terrifies me. I just don't know how long we can put off removing it.

Here is a photo of dd's mouth, so you can see what I'm talking about. It's partially hidden by her lip.
