Although thyroid cancer is a relatively uncommon form of cancer in cats, it's nonetheless something that every pet owner should be aware of as his or her cat begins to grow old. This form of cancer can be of two different types. One is a benign growth that will cause certain symptoms but not present a greater health concern, and the other is a malignant form of the disease that must be treated promptly before it can metastasize and spread to other parts of the body. Recognizing your pet's thyroid cancer is the first step toward treating this condition. Read on for the most common symptoms of thyroid cancer in cats.
Dramatic Increase in Appetite
It's common for older cats to have changes in appetite anyway, but cats suffering from thyroid cancer are likely to have dramatic increases in appetite. You may notice that your pet consumes all of his food as well as the food of other cats in your home. He may try to eat human food and may even be seen attempting to open up cupboards to get access to additional food as well. The reason for this is that the thyroid cancer oftentimes prompts an overproduction of certain thyroid hormones that help to control appetite.
Along with an increase in appetite, you may quickly see an increase in your pet's weight as well. This can cause a variety of health problems in and of itself, thereby giving you even more of a reason to eliminate your pet's cancer as quickly as possible. Notably, however, some cats experience weight loss as a result of thyroid cancer.
Changes in Energy Levels
Another thing that may happen to your cat is a dramatic change in his energy levels. Look for older cats that were previously very sedate and lethargic suddenly behaving as if they were much younger. Many pet owner's mistake this symptom of thyroid cancer for a "second youth" or an energetic phase.
Vomiting and Thyroid Cancer
Pets with thyroid cancer tend to vomit much more frequently than cats that are otherwise healthy. Observe your pet for changes in his behavior in this regard.
Thyroid Cancer and Panting
Unlike dogs, cats do not regularly pant. If you notice your pet panting at all, it is a sign that something is seriously the matter with his health. Cats suffering from thyroid cancer will tend to pant, although this symptom is not enough for a conclusive diagnosis in and of itself.
If you notice these or any other symptoms that you think may suggest that your pet has thyroid cancer, take him in to the vet immediately. The vet will begin with a thorough physical examination and will continue with a set of blood samples and exams. He may even request a biopsy to be performed in order to conclusively diagnose the condition. The sooner that you're able to diagnose your pet's thyroid cancer, the better the odds are that you'll be able to treat your pet fully.
