My five year old Lolly had the surgery earlier this year. My vet said she felt surgery was the best option given her age but wouldn't put an elderly rabbit through it. I also had Esme, around the same age as your rabbit - somewhere around nine years discovered to have a lump at her ear base (at health check for vaccination, I guess), she wasn't showing any symptoms either. She was just monitored for the last two years of her life and it never obviously bothered her.
I think you are right not to rush into doing it.
