Really depends on the vet's philosophy. Lumps and bumps that don't look suspicious are left here as long as they aren't getting too much bigger. If the vet thinks it needs to be removed if it grows and that a local couldn't be used if it gets much bigger and you think it is getting bigger, then I'd go ahead and do it before general anesthesia is required (unless she needs a dental anyway).
Removing lumps is no big thing. No reason to use general anesthesia unless it's really needed though. Though can sedate her alone with the local if she won't let them do it. With a couple restrainers, they may be able to though. Ellie had a punch biopsy on the top of her nose with just a tech holding her body and me holding her face. She did fine with it (she is an extremely wiggly girl).
These types of lumps are almost never serious. Just another thing to have to deal with...
