For many of us, pets are more than just companions—they’re cherished family members who bring warmth, joy, and unconditional love into our lives. Detecting signs of illness early can make a meaningful difference in their treatment options and quality of life. At Arcata Animal Hospital, our dedicated team is here to guide and support you, offering advanced cancer care from diagnostics through compassionate treatment.
This guide explores common cancers in pets, what symptoms to watch for, how to stay proactive with preventive care, and why veterinary expertise is invaluable.
Understanding Cancer in Pets
Cancer in pets happens when cells grow out of control, forming masses, or tumors, that can affect various organs or tissues. Just like in humans, cancer in pets can take many forms, each with its own set of characteristics. Some of the more common cancers seen in pets include lymphoma, mast cell tumors, osteosarcoma, and oral melanoma.
Lymphoma affects the lymph nodes, with symptoms like swollen nodes, fatigue, and weight loss. Mast cell tumors are often found on the skin and may cause itching or redness, while osteosarcoma, a bone cancer mostly affecting large dogs, can lead to limping and persistent pain. Oral melanoma, which appears in the mouth, may cause difficulty eating, drooling, or bad breath. Understanding these types can help you be on the lookout for subtle signs that may indicate cancer, giving your pet a better chance at early intervention.
Recognizing Symptoms of Cancer in Pets
Pets are masters at hiding discomfort, which can make recognizing the symptoms of cancer challenging. However, by closely observing your pet’s behavior and physical changes, you can often spot signs that warrant a veterinary consultation. Here are some key symptoms to watch for, along with explanations of what they might indicate:
- Persistent Lumps or Swellings
Not all lumps are cancerous, but any new growth or one that’s changing in size, shape, or texture should be examined by a veterinarian. Some cancers, such as mast cell tumors, can appear as small, red, or irritated lumps on the skin. Early evaluation helps determine if the lump is benign or requires treatment. - Unexplained Weight Loss
If your pet is losing weight without a change in diet or activity level, this could indicate an underlying issue. Certain cancers, particularly those affecting the gastrointestinal system, can lead to rapid weight loss as they disrupt nutrient absorption. Sudden weight loss in pets is a red flag that should prompt immediate veterinary attention. - Changes in Appetite
Both an increase or decrease in appetite can be concerning. Some cancers may cause pets to lose interest in food due to pain or nausea, while others may result in increased hunger due to metabolic changes. Observing shifts in eating habits can help catch underlying health issues early. - Abnormal Discharges
Blood, pus, or other unusual discharges from any part of the body, including the mouth, nose, eyes, or anus, could signify an infection, inflammation, or even cancer. For instance, certain oral cancers can cause bleeding from the mouth, while nasal tumors might lead to bloody nasal discharge. - Foul Odor
A persistent foul smell from the mouth, ears, or any other area can be indicative of cancer, especially in cases where there is tissue necrosis (death of cells) or infection. For example, oral tumors can lead to a distinct odor as they cause decay in the mouth. If you notice an unusual smell that doesn’t go away with regular grooming, it’s worth discussing with your veterinarian. - Difficulty Eating or Swallowing
Tumors in the mouth, throat, or esophagus can make it challenging for pets to eat or swallow comfortably. If your pet seems hesitant to eat, is drooling excessively, or has trouble chewing, it’s important to have them evaluated. Oral discomfort or difficulty swallowing is often one of the more visible signs that something may be wrong. - Lethargy or Low Energy
While a decrease in energy can be a common sign of aging, sudden or extreme lethargy may indicate that something more serious is going on. Cancers, particularly those affecting the organs or blood, can drain a pet’s energy, leaving them less interested in play, exercise, or even daily activities. - Persistent Pain or Discomfort
Pets experiencing persistent pain might become more vocal (whining, whimpering) or exhibit protective behaviors, such as avoiding touch or hiding. Bone cancers, such as osteosarcoma, can cause significant pain, especially in large-breed dogs. Limping or favoring one side of the body could be signs of discomfort that need evaluation.
By being aware of these symptoms, pet owners can play an active role in their pet’s health, helping to detect potential cancer signs early. If you notice any of these symptoms in your pet, schedule an appointment with your veterinarian promptly. For more urgent issues, please consult our Pet Emergencies page for guidance.
Prevention and Understanding Genetic Risks
While not all cancers are preventable, there are ways to reduce risk. Genetics plays a role, meaning certain breeds, like Golden Retrievers and Boxers, are predisposed to cancers like lymphoma or mast cell tumors. Similarly, larger breeds like Rottweilers and Great Danes are more likely to develop bone cancer due to their size.
Staying proactive about preventive care can help. Regular veterinary exams are essential because they allow for early detection. Beyond that, a balanced diet and healthy weight management can support your pet’s immune system, while minimizing exposure to carcinogens like secondhand smoke and pesticides reduces environmental risks. Spaying and neutering also offer health benefits that lower cancer risks in some cases. By building a foundation of preventive care, you’re actively supporting your pet’s long-term well-being.

Why Veterinary Care Matters and Diagnostic Tools We Use
We use various diagnostic tools to assess symptoms accurately and monitor progress. X-rays, for example, can reveal tumors or bone abnormalities, while ultrasounds help us examine soft tissues, such as the liver and kidneys, to spot potential tumors. Sometimes, a biopsy is necessary to determine if a mass is cancerous, allowing us to tailor treatments more precisely.
Blood tests and other lab work can also provide critical information about your pet’s internal health. Our experienced team knows how to interpret these results to develop effective treatment plans, always keeping your pet’s comfort in mind. By catching potential issues early and understanding the full scope of your pet’s condition, we can offer a care plan that aligns with their needs and your goals.

Treatment Options and Supporting Recovery
Cancer treatments in pets vary widely based on the type, location, and stage of the disease. Our team develops personalized treatment plans that may include surgery, chemotherapy, or even radiation therapy, depending on what will be most effective and least invasive.
Throughout the treatment process, pain management and quality of life are our top priorities. We work with pet owners to ensure their pets feel comfortable and supported, offering pain relief and supportive care when needed. A pet’s cancer journey is unique, and our team is here to guide you through it, from planning and monitoring treatment to providing ongoing support and reassurance.
How You Can Support Your Pet During Cancer Treatment
