Dogs and cats can develop cancer almost anywhere in the body, which is why the symptoms vary depending on the tissues and organs involved and the severity of the disease. Make an appointment with your veterinarian if your pet displays any of the following 10 warning signs of cancer in pets:
1. Unusual swellings that don't go away or that grow - The best way to discover lumps, bumps, or swelling on your dog or cat is to pet him.
2. Sores that won't heal - Non-healing sores can be a sign of infection or cancer and should be evaluated by your veterinarian.
3. Weight loss - Illness could be the reason your pet is losing weight but isn't on a diet.
4. Loss of appetite - Reluctance or refusal to eat is another sign of possible illness.
5. Bleeding or discharge - Bleeding can occur for a number of reasons, most of which signal a problem. Unexplained vomiting and diarrhea are considered abnormal discharges, as well.
6. Offensive smell - An unpleasant odor is a common sign of tumors of the anus, mouth, or nose.
7. Difficulty eating or swallowing - This is a common sign of cancers of the mouth or neck.
8. Reluctance to exercise or low energy level - This is often one of the first signs that a pet is not feeling well.
9. Persistent lameness - There can be many causes of lameness, including nerve, muscle, or bone cancer.
10. Difficulty breathing, urinating, or defecating - These symptoms should be evaluated by your veterinarian as soon as possible.
