Grade 2 mast cell tumors are the most difficult to predict. Grade 3 are the most serious and mean that the cancer has moved into surrounding organs. Grade one are very small and confined to a specific area, can be removed with very clean margins. Grade 2 are unpredictable--sometimes they come back and sometimes they don't, sometimes clean margins, sometimes not. My Paxil has had two bouts with Grade 2 mast cell tumors. In her case they reoccur every 8-12 months. They are the most common of all cancers in dogs and are extremely common in boxer type dogs. Most often they are simply removed and no further treatment is needed. Paxil was back in harness, by her own choice, ten days after her last removal in February 2006.

Hope you get good test results back.
