It sounds to me like it's a tumor.
The fish has already had it for a year and since there are no other
symptoms other than growth in size, there's not much you can do.
I've had several fish live with growing tumors for many years.
It might not look so pretty in another year or so. I've seen fish with
enormous tumors.
