When to see a pathologist for a mast cell tumor?

Additionally, the pathologist will determine the margin of normal cells around the tumor to assess whether surgical removal was complete or incomplete.
What to do with a Grade 3 mast cell tumor?
Chemotherapy is recommended for grade 3 tumors, if there is evidence of spread, or if the tumor can’t be removed. Radiation therapy is given as a small dose of powerful X-rays for multiple treatments over approximately four weeks.
Are there any drugs for canine mast cell cancer?

What’s the life expectancy of a mast cell tumor?
Most mast cell tumors can be treated with surgical removal without a recurrence. It’s important to note that very aggressive tumors (considered Grade 3) are also the least common. The life expectancy of a dog with an aggressive tumor that has spread to other parts of the body (mediatized) is roughly 4 to 6 months.
Can a mast cell tumor spread to the skin?
Mast cell tumors that fall into the grade II category are also found under the skin. In this case, the tumor’s position is deeper and more likely to spread. It might not have spread yet, however. This grade of mast cell tumor could be malignant. This is not the grade you want your dog to get. The tumor is deep within the tissues.
