One man's commentary on his dog's cancer
What is Intestinal Lymphosarcoma?
Intestinal lymphosarcoma is simply a form of lymphoma (cancer of the lymph system) occurring in the gastrointestinal tract. It accounts for only 5-7% of lymphoma cases in dogs. A good discussion of this cancer can be found here.
The most insidious part of this kind of lymphoma is that it sometimes shows no symptoms until it has a serious foothold. This was the case for Holly -- Nothing seemed to be wrong until she got a fever one afternoon.
