Dr. Phils Top Facts About Cancer and Your Pets: Dr. Phil Zeltzman shares these important facts about cancer and your pets. Top 10 signs of cancer: “I just can’t believe we couldn’t tell Missy had cancer,” said my teary-eyed client. “There were no warning signs,” she added, as we discussed the biopsy results after removing a cancerous mass in the intestine. It is notoriously difficult to detect cancer early in pets. Let’s get rid of a common myth: in many cases, cancer cannot be detected on blood work. However, there are 10 things you can look for, according to the American Veterinary Medical Association and the Veterinary Cancer Society. Even if the condition turns out not to be cancer, you may be able to detect another medical condition that needs veterinary attention. Also, it is critical to remember that a pet can be very sick “inside”, without showing any of the signs “outside” (as in Missy’s case), which is why we recommend regular veterinary checkups, ideally every 6 months. Early detection is key, so here are 10 common signs that may indicate that your pet could have cancer. 1. Abnormal swellings that persist or continue to grow The most obvious example is a mass (or bump, or lump) that keeps growing under the skin. Any surgeon will recommend that you don’t just “watch it”, but have it removed AND biopsied. If the mass turns out to be benign, that’s great. If it is malignant or cancerous, then we know and we can discuss what to do next. 2. Sores that do not heal These are typically skin wounds that don’t seem to heal despite antibiotics by mouth or an ointment applied locally. This also applies to no-healing wounds near a nail. 3. Weight loss This means unexplained weight loss, i. e. not explained by a weight-loss diet. Common causes could include a tumor along the intestine, as in Missy’s case. 4. Loss of appetite Similarly, a mass pushing along the intestines may make your pet feel bad. One of the first things a pet will then do, is stop eating. 5. Difficulty eating or swallowing For example, a lump in the neck could be putting pressure on the esophagus (the tube between the mouth and the stomach). 6. Bleeding or discharge from any body opening Bleeding from the nose, although it does not necessarily mean cancer, is certainly a common sign of cancer of the nose. 7. Offensive odor I remember a sweet Bulldog we recently treated. She had a large mass near her anus. Biopsies showed that it was cancer. The odor stemmed from multiple draining tracts from which pus came out. A culture showed that 4 different bacteria were growing in there! 8. Reluctance to exercise or loss of stamina We recently saw a 9 year old Rottie who had a tumor on the heart. Because of the bleeding and the pressure on the heart, he certainly did have difficulty exercising. 9. Persistent lameness or stiffness We see lame pets every single day, but luckily they rarely have cancer! However, bone cancer can cause pain and lameness, along with swelling along the leg. 10. Difficulty breathing, urinating or defecating This could be due to a mass putting pressure on the respiratory (wind pipe, lung), urinary (bladder, urethra) or digestive (rectum, anus) systems. Early detection is paramount. While there is no reason to be paranoid, stay informed, keep your eyes open, pet your pet all over and often, and see your family vet regularly for checkups. Whether to detect cancer or any other condition, these are pretty safe recommendations to keep your pet happy and healthy for a long time!
