Can Pets Get Mesothelioma? Surprising Facts for Pet Owners

Mesothelioma is a rare cancer often linked to asbestos exposure in humans. But what about our furry friends? Can pets like dogs and cats develop mesothelioma? Science says yes—though it’s very rare. This blog shares proven facts about mesothelioma in pets, how it happens, and how to keep your pets safe.

It is a serious cancer tied to asbestos exposure, is widely known to affect humans. But could this danger also threaten our beloved dogs and cats? Veterinary research confirms that pets can develop mesothelioma—though cases are extremely uncommon. In this blog, we’ll explore how asbestos impacts animals, recognize warning signs, and share science-backed tips to safeguard your furry family members.

Can Pets Really Get Mesothelioma?

Yes, but it’s extremely uncommon. According to the Journal of Veterinary Diagnostic Investigation, fewer than 5% of pet cancers are mesothelioma. Most cases are in dogs, but cats and other animals can also be affected. For example, a 2018 study in Veterinary Pathology reported a case of mesothelioma in a dog exposed to asbestos in an old home.

How Are Pets Exposed to Asbestos?

Pets can encounter asbestos in ways similar to humans:

Old Homes: Houses built before 1980 may have asbestos in insulation, tiles, or pipes. Renovations can release fibers into the air.
Secondhand Exposure: If owners work with asbestos (e.g., construction), fibers can stick to clothes or tools and spread at home.
Environment: Natural asbestos deposits exist in some U.S. states (e.g., California, Virginia). Pets playing outdoors may inhale fibers.
Consumer Products: Older pet toys, bedding, or car brakes could contain asbestos.

Fact: The EPA warns that 30 million U.S. homes still contain asbestos materials.

Symptoms of Mesothelioma in Pets

Symptoms are vague and mimic other illnesses. Watch for:

Difficulty breathing (common in lung-related mesothelioma)
Lethargy or loss of appetite
Swollen belly (fluid buildup in abdominal cases)
Coughing or wheezing

Important: These signs don’t always mean cancer. Always visit a vet for a checkup.

Diagnosing Mesothelioma in Pets

Vets use tests like:

X-rays or CT scans to spot tumors or fluid.
Biopsies (taking a tiny tissue sample) to confirm cancer.
Blood tests to rule out other diseases.

The diagnosis is tricky because mesothelioma is rare. Specialized labs like the Michigan State University Veterinary Diagnostic Lab help identify cases.

Treatment Options for Pets

There’s no cure, but treatments can improve quality of life:

Surgery: Removing tumors if they’re small and localized.
Chemotherapy: Slowing cancer growth (used cautiously due to side effects).
Palliative Care: Draining fluid from the chest or abdomen to ease breathing.

Note: Treatment success depends on how early the cancer is found.

How to Protect Your Pet from Asbestos

Check Your Home: If your house was built before 1980, hire a professional to test for asbestos.
Avoid DIY Renovations: Disturbing old materials can release fibers. Keep pets away during repairs.
Wash Work Clothes: If you work with asbestos, shower and change clothes before interacting with pets.
Monitor Outdoor Play: In areas with natural asbestos, limit digging or dusty activities.

Did You Know? The EPA’s 2023 guidelines recommend sealing (not removing) asbestos materials if they’re in good condition.

FAQ

Q: Is mesothelioma contagious between pets or humans?
A: No. Mesothelioma is caused by asbestos exposure, not germs.

Q: What’s the life expectancy of a pet with mesothelioma?
A: It varies. With treatment, some pets live months to a year.

Q: Are certain breeds at higher risk?
A: No proven link, but dogs with longer lifespans (e.g., smaller breeds) may show more age-related cancers.

Q: Can I sue if my pet gets mesothelioma from asbestos?
A: Laws vary by state. Consult a legal expert familiar with environmental toxicity cases.
