When a Simple Lump Might Mean Something More

Finding a lump or bump on your pet can be frightening. Your mind immediately jumps to the worst—is it cancer? November is Pet Cancer Awareness Month, making it the perfect time to learn which lumps may be harmless and which require a closer look. At Advanced Pet Care in Cedar Falls, we want pet owners to understand what these changes can mean and how early detection can make all the difference.

Why Awareness Matters

Cancer is one of the most common health concerns in pets, especially as they age. According to veterinary studies, one in four dogs and one in five cats will develop cancer in their lifetime. While that number sounds alarming, the good news is that many cancers—when detected early—can be treated or managed successfully.

The key is knowing what to watch for and acting quickly if you notice something unusual.

Lumps and Bumps: Not Always a Cause for Panic

Not every lump means cancer. Pets can develop a variety of skin growths, many of which are benign (non-cancerous). The chart below highlights some of the most common types of pet lumps and how they differ between benign and malignant growths.

Benign lumps may stay the same size for years, while malignant (cancerous) tumors tend to grow, change, or cause discomfort.

When to Be Concerned About a Lump

If you find a lump, take note of its size, texture, and location. Then watch for warning signs that mean it’s time to call your veterinarian:

  • The lump grows quickly or suddenly changes shape
  • It feels hard or fixed under the skin
  • The area becomes red, ulcerated, or painful
  • There is bleeding or discharge
  • Your pet shows weight loss, loss of appetite, or fatigue
  • Multiple new lumps appear over a short period

If you notice any of these changes, do not wait—schedule an exam right away.
Even if the lump seems small or harmless, your veterinarian may recommend monitoring it or testing it now for peace of mind.

How Cancer Screenings Help Detect Problems Early

During a cancer screening or physical exam, your veterinarian at Advanced Pet Care will carefully evaluate any new or existing lumps. Screenings may include a thorough exam and, if needed, additional diagnostic steps to determine whether a growth is benign or malignant.

Early detection is often the deciding factor in treatment success. Even small changes can reveal valuable information about your pet’s health, which is why regular wellness exams—and quick follow-up when you notice something new—are so important.

Hope and Healing Through Awareness

Hearing the word “cancer” is scary, but it does not always mean there’s no hope. Many forms of pet cancer can be treated, slowed, or managed with the right care plan. What is most important is not to delay getting that lump checked.

By learning what to look for and scheduling annual cancer screenings, you are giving your pet the best chance for a long, healthy life.

Check for Lumps During Grooming

Regularly grooming your pet is not only about keeping their coat healthy — it is also one of the best ways to catch health problems early. While brushing your dog or cat, take a moment to gently feel along their body for any new lumps, bumps, or changes in the skin. Pay attention to areas like the chest, belly, and under the legs, where growths often go unnoticed beneath fur.

Make it part of your routine: a quick check once a week can help you spot changes long before they become serious. If you notice anything new or unusual, schedule an exam with Advanced Pet Care to have it evaluated. New to DIY grooming? You can learn the basics in our Pet Grooming for Dogs and Cats.

Do Not Forget the Mouth

Mouth checks matter, too. Once a week, lift your pet’s lips and look along the gums, cheeks, and under the tongue for unusual lumps, sores that do not heal, bleeding, foul odor that’s new or worsening, drooling, difficulty chewing, dropping food, or one-sided facial swelling. If you spot any of these changes—or a mass in the mouth—schedule an exam with Advanced Pet Care. We will check your pet’s mouth during their routine wellness and dental visits.
