Can you leave a mast cell tumor?
Most mast cell tumors are easily removed without any further problems, while others can lead to life threatening disease. When the entire body is affected, the disease is referred to as mastocytosis. Normal mast cells are present in most tissues, especially the skin, lungs and digestive tract.
Do mast cell tumors always spread?
Fortunately, the majority of mast cell tumors are localized to one spot. However, rarely they will spread to lymph nodes, the blood, the spleen, the liver, the lungs, the bone marrow, or other skin locations. If the tumor spreads, or metastasizes, to other areas of the body, multi-modality therapy will be required.
How are mast cells removed from the body?
Mast cell tumors invade into surrounding tissues and wide surgical margins (wide area of healthy tissue surrounding the tumor Figure 2 and Figure 3) are necessary to ensure removal of all cancerous cells. The excised (removed) tumor will be submitted for histopathology for confirmation of the tumor type and grading.
Can a mast cell tumor be removed from a dog?
Mast cell tumor dogs often will have a lump on the skin that can look or feel like almost anything. Many low-grade mast cell tumors can be cured with prompt surgical removal, but high grade mast cell tumors have a guarded prognosis potentially requiring radiation or chemotherapy. What is a mast cell tumor in dogs?
Can a mast cell tumor be left untreated?
Unfortunately, mast cell tumors can be invasive dog skin cancers that have the potential to spread to other areas of the body if left untreated. This form of cancer in dogs will often continue to grow and get worse if not treated.
What kind of excision is needed for mast cell tumor?
For example, benign skin tumors such as epidermal inclusion cysts require only a marginal excision and routine skin closure. Malignant skin tumors, such as mast cell tumor (MCT), require extensive tissue resection (e.g. removal of 2-3 cm of normal tissue with the mass) followed by more complicated reconstruction in some cases.

What is the best treatment for a mast cell tumor?
For most tumors, regardless of grade, additional therapy is recommended if the initial surgery was unsuccessful in removing the entire tumor. Options include a second surgery or radiation therapy. Chemotherapy can be used instead of surgery and/or radiation therapy to limit regrowth of an incompletely removed tumor, but the efficacy can be low.
