When it comes to our pets’ health, early detection of any health issue can make a world of difference, especially with serious conditions like cancer. Just like in humans, early diagnosis often opens up more treatment options, giving our pets a better chance at managing or even overcoming the disease.
Cancer is one of the leading causes of death in dogs and cats, particularly as they age. While it can sound scary, knowing the common signs that your pet may have cancer and the tools available to detect cancer may empower you to take action sooner. This could make a difference in the prognosis of your pet's disease.
These are the top 5 signs you may notice in your pet if they have cancer:
1. Unexplained Lumps or Bumps
Finding lumps or bumps on your pet can be worrying, but not all growths are cancerous. However, any new or changing lump should be checked out by your veterinarian. Lumps that grow quickly, feel irregular in shape, or are firmly attached to the underlying tissue are especially concerning. Your vet might recommend a biopsy or fine-needle aspiration to check for abnormal cells.
2. Unusual Weight Loss
Unintentional weight loss, especially in pets that are eating normally or even more than usual, can be a warning sign. Some types of cancer cause a pet’s body to consume more energy, leading to weight loss even with a good appetite. If your pet is losing weight unexpectedly, it’s time for a vet visit to rule out cancer or other illnesses that could be causing it.
3. Changes in Appetite or Difficulty Eating
Pets with oral tumors or cancers affecting the digestive system may have difficulty chewing, swallowing, or simply show less interest in food. Cats, in particular, are sensitive eaters, and even small changes in their eating habits should be addressed. Look for symptoms like drooling, foul breath, or reluctance to chew on their favorite toys as possible indicators of oral cancer or other internal issues.
4. Persistent Cough or Breathing Issues
While respiratory issues can result from many causes, a persistent cough or difficulty breathing can sometimes be a symptom of lung cancer or metastatic cancer, particularly in older dogs and cats. If your pet seems to tire easily, wheeze, or breathe heavily, it’s worth having your vet listen to their chest and possibly conduct imaging tests to check for masses or fluid buildup around the lungs.
5. Changes in Behavior or Mobility
Cancer can cause pain, swelling, and discomfort in different parts of the body, especially if it spreads to the bones. If your pet suddenly becomes less active, limps, avoids jumping or playing, or appears generally stiff or sore, it’s essential to have them evaluated. Changes in mobility, reluctance to be touched, or hiding can all indicate underlying pain.
The Nu.Q® Test: A New Option for Early Cancer Detection
Recently, there’s been a significant advancement in cancer detection for pets—the Nu.Q® test. Originally developed for humans, this blood test has been adapted to detect signs of cancer in dogs and, eventually, cats. The Nu.Q® test measures nucleosomes, which are fragments of DNA that are released into the bloodstream when cancer cells die. Elevated levels of these nucleosomes can indicate the presence of cancer, even in its early stages.
This test is especially beneficial because it’s non-invasive—it requires only a simple blood sample—and can detect certain cancers before physical signs even appear. As of now, the Nu.Q® test is primarily used to detect lymphoma and hemangiosarcoma in dogs. However, as research progresses, the test may become more widely applicable for other cancers and for cats as well
While the Nu.Q® test isn’t a definitive diagnosis of cancer, it can be a helpful screening tool. If the results indicate elevated nucleosome levels, your vet may recommend further diagnostic tests, such as X-rays, ultrasound, or a biopsy, to investigate further.
Awareness and vigilance are the first steps toward protecting our pets from cancer. By keeping an eye out for the signs listed above and discussing options like the Nu.Q® test with your veterinarian, you’re empowering yourself with the tools to give your pet the best possible care.
If you have any questions about your pet’s health or want to discuss early cancer screening, don’t hesitate to reach out to your veterinarian.
