When to Stop Fighting Mast Cell Tumors in Dogs


Mast cell tumors (MCTs) are a type of cancer that can affect dogs. These tumors are usually found on the skin, but can also develop in other areas such as the lymph nodes and internal organs. MCTs can be life-threatening if left untreated, so it is important to know when to stop fighting them.

Causes of Mast Cell Tumors in Dogs

The exact cause of mast cell tumors in dogs is unknown, but some factors may contribute to their development. Certain breeds, such as Boston Terriers, are more likely to develop MCTs than others. Allergic reactions and exposure to certain toxins or chemicals may also increase the risk of developing this type of tumor.

Symptoms and Diagnosis

Symptoms of mast cell tumors can vary depending on the location and size of the tumor. Common signs include swelling, itching, hair loss, ulceration or bleeding from the tumor site, and skin discoloration or lesions. If your dog is exhibiting any of these symptoms, it is important to take them to a veterinarian for diagnosis as soon as possible. Diagnosis typically involves a physical examination and biopsy of the tumor site. Other tests such as bloodwork and imaging may also be necessary to determine if the tumor has spread or affected other parts of the body such as bone marrow or lymph nodes. Once a diagnosis has been made, your veterinarian will be able to determine an appropriate treatment plan for your pet’s specific case.

Treatment Options

Treatment options for mast cell tumors depend on several factors including the grade (severity) of the tumor and its location within the body. Surgical removal is often recommended for low grade MCTs located on or near the skin surface; however, higher grade tumors may require additional treatments such as radiation therapy or chemotherapy under the guidance of a veterinary oncologist. In some cases, systemic medications may be prescribed in order to reduce allergic reactions caused by mast cells that have spread throughout the body via circulation in blood vessels or lymphatic systems.

Survival Time & Quality Of Life

The prognosis for dogs with mast cell tumors varies depending on several factors including grade, size,location and stage at which treatment begins.The average survival time after diagnosis ranges from 6 months - 2 years depending on how aggressive treatment was pursued.The quality of life during this time will depend largely on how well symptoms were managed,which treatments were used,and how quickly any side effects were addressed.
