I'm far from an expert, but I've sure been around long enough to see so many tumor stories.
I have notes about diets for the young to avoid them when they're older, various treatments for them when they have already occured.. only thing I've seen that has actually shown any real verifiable effect is spaying to lessen the chance of mammary tumors.
Other than that tumors are lawless & conscientiousless. There are no rules at all. Either in who gets them or how quick they grow or where they hit. You can remove some but not the heartbreakingly frequent Pituitary Tumors, those are game over. Other tumors you can ask the vet to send off a sample to find out whether its benign (local & harmless& not likely to recur) or if it's worse. There is a good chance (not a certainty) that other tumors will pop up again after surgery - same place or somewhere else. Mammary tumors are more likely than not to recur without a spay.
You know, Once they leave your hands..... bottom line is that it's all gonna come down to your vet's skill & knowledge. That is the bottom line and either the end of the line or the beginning.
