Chester needs surgery :-(

I took my big orange cat Chester to the vet this week and we discovered a cyst on his right hindleg during his check up. Light microscopy of the biopsy revealed oddly shaped cells with prominent nucleoli (indicative of cell division). Cysts are usually benign, but the odd biopsy result prompted the vet to recommend surgery to remove it. So we're scheduled for Tuesday, Oct 12th. I'm surprised that I hadn't noticed it on my own, but on the other hand, I rarely pet his hindleg. He has no other symptoms, and is in very good health for a 10 year old cat. He has lost a pound since his last year's check up, but at 15.2 pounds, the vet says that's nothing to worry about. I'm going to have his teeth cleaned while he's under as preventative maintenance as well. I was feeling like a bad cat daddy because I scheduled his surgery in two weeks to better fit my schedule, rather than right away, but the vet said that it was not an emergency, so I am becoming ok with that. Of course, now I will be hypervigilant about everything he does before the surgery, but I will also give both him and Sawyer lots of love.
