Cancer is a common problem not only in people, but in our pets as well. If diagnosed early, treatment can either cure or achieve remission giving the pet a longer and good quality of life. The mainstays of treatment aren't much different from those recommended for people - surgery, chemotherapy and/or radiation therapy. While the costs of such treatments are nowhere near the cost in human medicine, it can still run into the thousands of dollars. Most pet insurance companies cover cancer treatments as long as the condition wasn't pre-existing.
