Thankfully the lipoma was not cancerous and there have been no complications at all. Her post-op recovery was two days and within a week she was as good as new.
We did go through a university vet hospital (auburn) as opposed to our local vets. All told, it was the best experience we could have had given the circumstances.
Any other specific questions, I can answer over email
We decided on going ahead with the procedure for a number of reasons, most importantly we thought it would be better to deal with her massive (and I mean massive) lipoma before it ruptured and things got really ugly.
