About 3 years ago, my cat was diagnosed with Cancer (Lymphoma). The vet told us that if we went with surgery, the best we could hope for is another year or two before it returned. She was 10 years old at the time and already to the point where she was eating very little due to her stomach being constricted by the tumor. We had her put down the following week.
Are there types of cancer where treatment is actually a viable option? How likely is it to even diagnose when odds of success are good? (In my cat's case, an x-ray done 7 months prior showed no signs of a tumor).
