Did you know that Mast Cell Tumors represent 14-21% of all skin tumors in dogs? And certain breeds, like Retrievers, etc are more susceptible to getting them? Our marketing "guru" Tiina recent lost her dog of 11 1/2 years, Jackson, to Mast Cell Tumor (MCT), a type of cancer. Tiina shares that "It was quick, aggressive and a silent killer. It all started with one lump that appeared to be an 'abscess' to their vet and shortly after was biopsied, finding it to be stage 3 MCT, the highest grade. Jackson's family searched for options to treat, both holistic and traditional and researching the disease and implemented holistic options first, as they waited to see an oncologist. It was within a one week span that Jackson's condition worsened and they found it had spread internally to many organs and resulted in internal bleeding of his GI tract. They had started chemo, but it was too late and he was dying". Jackson left behind his SGRR brother, Arlo, his two human sisters, Emmeline and Luciana and his human parents, Tiina and Greg. "We miss him every single moment of every single day. We want to spread awareness and help educate others, so you can save your "Jackson", when we couldn't. If anyone has any questions or wants to reach out, comment on the post and I will be happy to share anything and everything that I've learned about this terrible disease".
In the meantime, here's some information about Mast Cell Tumors so you can be educated and aware of what to look for. As always, for anything medical, please work with your veterinarian.
Mast Cell Tumors (MCTs) are the most common skin cancer in dogs, appearing as varied lumps and skin growths. While they primarily affect older dogs of any breed, some breeds like Boxers and Bulldogs are predisposed. Early detection through regular physical checks for lumps, followed by a biopsy for diagnosis and grading, is crucial for a good prognosis, as low-grade MCTs are common, and effective treatments like surgery or injections exist.
What to Know About Mast Cell Tumors
Prevalence:
MCTs are the most common skin tumor in dogs, accounting for about 20% of all skin tumors.
Appearance:
They can vary widely in appearance, from small, hairless nodules to larger, ulcerated masses, or even diffuse lesions.
Location:
While most common on the trunk, limbs, and head/neck, they can also affect internal organs.
Age and Breed:
MCTs are more common in older dogs but can occur at any age and affect all breeds, though some breeds, such as Boxers, Pugs, Boston Terriers, and Bulldogs, are more predisposed.
Why Awareness Matters in 2025
Early Detection: Early detection through routine physical exams is key for better outcomes.
Biopsy for Grading: A biopsy is necessary to determine the tumor's grade, which greatly influences the prognosis and treatment plan.
Prognosis: Low-grade MCTs (the most common type) generally have a good prognosis, while high-grade tumors have a much poorer outlook, especially if untreated.
What to Do If You Find a Lump
Perform Regular Self-Exams: Check your dog for any new or changing lumps and bumps.
Consult Your Veterinarian: Schedule an immediate veterinary appointment to have any suspicious lumps examined.
Consider Proactive Screening: For high-risk breeds or for peace of mind, discuss proactive screening options with your vet.
