Let's Talk About Pet Cancer: What You Need to Know

Just How Common Is It?

You might be surprised to hear this, but about 1 in 4 dogs and 1 in 5 cats will face cancer at some point in their lives. And in older pets, cancer is the leading cause of disease-related death.

But don’t let those numbers scare you—early detection, modern treatments, and regular checkups can help keep your pet comfortable and by your side for as long as possible.

Signs to Watch For

Cancer can be sneaky, and pets are good at hiding when they’re not feeling well. Here are some signs that might warrant a vet visit:

• Lumps or bumps that are new or changing

• Unexplained weight loss or appetite changes

• Lethargy or lack of interest in play

• Sores that don’t heal

• Trouble eating, swallowing, or breathing

• Bleeding or discharge

• Stiffness, lameness, or mobility changes
  
  

Even if it’s not cancer, these symptoms could be a sign of something else—and it’s always better to catch things early.

Types of Cancer in Pets

Some of the most common cancers in pets include:

• Lymphoma – often affects lymph nodes and internal organs

• Mast cell tumors – a type of skin cancer, common in dogs

• Bone cancer – especially in large breed dogs

• Mammary tumors – more likely in pets that aren’t spayed

• Oral cancers – often discovered during routine dental checks

Certain breeds have higher risks, too. For example, golden retrievers, boxers, Great Danes, and Scottish terriers all have predispositions to different types of cancer. If you’ve got one of these breeds, keep an even closer eye out.

Prevention & Early Detection

While we can’t completely prevent cancer, there’s a lot we can do to reduce risks and catch it early:

• Schedule regular vet checkups, especially for senior pets

• Keep your pet at a healthy weight with good nutrition

• Spay or neuter to reduce the risk of certain cancers

• Check your pet regularly for new lumps or changes

• Limit exposure to tobacco smoke and environmental toxins
  
  

You know your pet best. If something seems off—even if it’s subtle—don’t wait. Trust your gut and call your vet.

What If My Pet Has Cancer?

We know how heavy that news can feel. But thanks to advances in veterinary medicine, there are more treatment options than ever:

• Surgery to remove tumors

• Chemotherapy or radiation therapy

• Immunotherapy

• Palliative care for comfort and quality of life

The right approach depends on your pet’s type of cancer, their age, and overall health. But with a great care team, your pet can still live a happy, love-filled life.

What You Can Do Today

Now’s a great time to take a step back and really look at your pet’s health. Ask yourself:

• When was their last checkup?

• Have I noticed any new lumps, bumps, or changes?

• Is their appetite and energy level normal?

Even small changes could be early signs of something bigger—and your vet can help you figure out what’s going on.
