Surprisingly, cancer is the leading cause of death among cats that are old. An uncontrolled growth of cells is normally the cause of cancer in cats and it affects several body organs and cells.

Though its exact cause has not officially identified, scientists suspect that the major contributor of cancer in cats is an organism called feline leukemia virus. However, there are factors known to increase the rates of cancer in cats such as second-hand smoking and excessive licking of body parts that have been in contact with a toxin.

Now, before being able to identify these signs and symptoms, it is important to know that there are different types of feline cancer. Therefore, it is also worth noting that the signs and symptoms might be different according to the different types. Cancer in cats can occur in any part of the body and a lot of the times the symptoms can be detected externally. Check if your cat has fallen victim to cancer by looking out for the following symptoms:


Occasional lumps and bumps can be common in cats. This means that not all lumps can be caused by cancerous cells so there is no foolproof way to tell for sure. However, if the bump does not resolve itself over an extended period of time or if it seems to be growing in size, this is most likely a red flag. Consult a vet. A needle biopsy is conducted by a veterinary pathologist to be able to tell whether or not your cat has cancer.

Abnormal odors

This is especially the case with cats that have cancer of the mouth, nose and anal regions. If your cat has an offensive odor coming from the mouth, ears or any other part of your body, you might have a reason to be worried. Get your pet checked out as soon as possible.

Wounds that heal slowly

Cancer has the effect of slowing down the healing process of wounds in cats and even in a lot of cases, preventing the wounds from healing at all. Get your cat screened for cancer if this happens.

Rapid weight loss

It is a proven fact that cancer is among the illnesses that are the cause of weight loss among pets. A sudden weight loss within a short period of time isn’t usually a good sign, especially if your cat is not on a diet. You need to mention this to your vet the next time you have an appointment.

Loss of appetite

Unless they have a reason, pets do not normally stop eating. A lack of appetite might be a strong indicator that your cat has cancer, specifically a tumor in the mouth. It may end up being nothing but it’s better to be safe than sorry.

Difficulty breathing

Coughing or an unusual breathing pattern can be the effects of a number of ailments such as heart disease and cancer. Cancer can metastasize through the lungs and cause these signs.


As you might probably know, a general lack of energy is often a sign that there is something up with your pet. Cats with cancer are usually less playful, sleep more and are less willing to exercise or go out. Just like a lot of other symptoms, this is not confined to cancer, so check for the other signs mentioned.
