Mast cell tumors are a common canine cancer, but are they painful for our canine companions? This blog post will explore the relationship between mast cell tumors and pain in dogs.
Mast cell tumors are a type of cancer that can affect several different tissues in dogs, and have the potential to spread to other organs within the body. While these tumors can vary in size and severity, one of the main concerns for pet owners is how much pain these tumors may cause for their pup. Pain is an important factor to consider when making decisions about treatment and management for our canine companions, and in this post we will dive into the details of mast cell tumors and the associated pain.
We will look at the symptoms and risk factors associated with these tumors, how pain can be managed, and possible treatment options. Additionally, we will review the impact that mast cell tumors can have on our four-legged friends and how pet owners can best care for their pup and recognize signs of pain
Causes of Mast Cell Tumors in Dogs
The underlying causes of mast cells tumors are not known. We don’t have enough information to suggest any changes to your dog’s environment to prevent mast cell tumors, but it’s likely that, like other types of cancer, they are brought on by a combination of genetic and environmental factors.
Mast cell tumors, however, are more common in some breeds. These include:
What is a mast cell?
Many body tissues contain a type of white blood cell called a mast cell. As allergy cells, mast cells contribute to the allergic reaction. Mast cells release chemicals and substances when exposed to allergens (substances that cause allergies), a process known as degranulation. One of these compounds is histamine. The most well-known effects of histamine are itchiness, sneezing, and runny nose and eyes, which are typical signs of allergies. However, when histamine (and the other compounds) are released in large quantities (with mass degranulation), they can have full-body effects, including the potentially fatal allergic reaction anaphylaxis.

Treatment of Canine Mast Cell Tumors in Dogs
The extent of the mast cell tumors and their expected behavior determine the course of treatment.
The most typical form of treatment for mast cell tumors is surgical removal. Determining whether the tumor was completely removed is crucial because if any of it remained, it could return to the same location. This is found in the biopsy evaluation following surgery. A second surgery may be required to remove the rest. Antihistamines are frequently prescribed prior to surgery to mitigate the effects of the histamine released from the mast cells.
Following surgery, biopsied tumors are examined and graded to determine their severity. The grade plays a significant role in determining the tumor’s rate of aggressiveness. The history of the tumor, the location of the tumor, your dog’s health, and his breed can all help with grade assessment. If your dog needs additional treatments, factors like the tumor’s grade, its spread, and whether there was enough tissue margin to completely excise the tumor are all taken into account.
Mast cells that couldn’t be removed can be treated with radiation therapy, which can be prescribed. For Grades I and II, surgery and radiation therapy are typically advised. Additionally, chemotherapy can be advised and is frequently only used for Grade III tumors.
To combat the ancillary problems brought on by the tumors, prescription medications may be given. These drugs can include antihistamines, antacids, and corticosteroids like prednisone.

FAQ
What are the final stages of mast cell tumors in dogs?
Mast cell cancer frequently has severe digestive symptoms, such as vomiting, diarrhea, and abdominal pain from stomach ulcers, which indicate the end of quality of life.
How long will a dog last with untreated mast cell cancer?
These tumors all have a poor prognosis, with median survival times of under 4 months. They behave aggressively and require more aggressive therapy. The median survival time of these tumors was more than 2 years overall, but some of them exhibited aggressive behavior in spite of their low grade.
How fast do mast cell tumors spread in dogs?
While some mast cell tumors develop gradually over time, others appear suddenly and spread quickly. In addition, they are prone to waxing and waning, swelling when the mast cells degranulate. The tumor and its surrounding areas may become itchy and grow larger if the tumor is handled, which can result in degranulation.
What is the survival rate for dogs with mast cell tumors?
The median survival (50% alive) following surgery is 6 months. The median survival increases to 12 months when chemotherapy is used in conjunction with surgery. When grade III tumors are only partially removed, we advise either additional surgery or radiation therapy.
