I am so very sorry for your losses. I apologize for the delay, I was in the process of responding to you...
This is a terribly difficult decision for anyone to make and moreso in your situation because you have had so much loss recently.
I guess the question is would you have more regrets if she passed not taking the chance of surgery that you could potentially have 2+ more years with her or if you elected surgery and she did pass during the procedure?
I was in your situation about 8 years ago with my 11 year old Chihuahua
. She had an abdominal mass that was found on a routine ultrasound (I do them preventatively on my dogs annually if they are over ten years old). I was absolutely devastated because she was my life but I elected to take the chance with surgery and she handled it like a champ. It ended up being a benign (non cancerous) mass in her abdomen and she lived another 3 years afterwards with no ill effects from the surgery. So in this situation I was very happy I did the surgery and knew going in there were risks but if it meant I would have her longer and the mass wouldn't grow and cause her discomfort (the recovery is often just a few weeks) then I was prepared to take that risk.
With her having normal bloodwork and is otherwise generally healthy for her age, it really is a personal decision that you need to be prepared to handle the decision either way. I am of the mind set that I would rather take the chance knowing I am doing what is going to give her the best chance versus watching and waiting knowing what is in there could cause her pain and end her life sooner.
That is my thought process but everyone is different. With so much loss in your life recently it is a much bigger leap of faith for you than it was for me...
I hope this helps but please let me know how else I can assist you and would love to know what you decide...
