Grading Mast Cell Tumors
There are three grades of mast cell tumors: Grade I (well-differentiated), Grade II (moderately differentiated) and Grade III (poorly differentiated). The type of treatment your pet receives depends on the tumor's grade.
If your dog has a Grade I mast cell tumor, its removal is likely the only treatment necessary. Grade II can also be treated by surgical excision only, but the veterinarian will likely run tests to ensure the cells haven't spread to other locations in your dog's body.
With Grade III, the veterinarian will still monitor your pet for metastasis and will also prescribe a combination of chemotherapy and radiation, as surgery alone isn't effective in treating the advanced grade.
Grades I and II carry an excellent prognosis when treated quickly and effectively. The outlook for Grade III should be much more guarded, as recurrences of the cancer are more likely. To ensure your dog has the best outcome possible, keep an eye out for growths and have them examined immediately.
