Ask Lance: Cat confusion

Dear Lance,
I have a 16-year-old cat who has developed a lump on her underside.
According to the vet, tests would need to be done to determine whether the lump is cancerous. If the lump needs to be removed, it would mean surgery and radiation.
Given the age of my cat and no sign of stress or discomfort, would you advise surgery?
At first I thought it was an easy decision… let nature take its course and don’t submit her to the stress and effects of surgery. Now I’m not so sure.
What would you do?
Confused about the Cat

Dear CC,
I can personally identify with your dilemma and I realize you are faced with a perplexing decision. However, due to the age factor and exorbitant costs involving surgical fees with no positive outlook, I would allow the privilege of enjoying life until such time that you become aware of any discomfort.
Why not follow your idea and let nature take its course? There could be months of enjoyment ahead, and when the time comes, you can then arrange for a quiet farewell. In any event, I would be reluctant to subject this precious kitty to surgery due to the variables involved.
With happy thoughts,
Lance Gablehowser
