What Is Lung Cancer in Cats?

Feline lung cancer is a type of cancer that is rare in cats. It is similarly quite uncommon in most dogs as well.

It significantly affects the respiratory system of felines and certain procedures should be conducted to get a definitive diagnosis.

Most primary lung tumors are often deemed as few far and between. It is much more common for cats to develop a tumor in the lungs after cancer has spread from another location than for the tumor to start in the lungs.

Depending on the circumstances and the extent of damage in the lung tissue, there may be solitary tumors or multiple tumors.

This is also the case for squamous cell carcinoma and cancers affecting other organs and parts of the body like fibrosarcoma, the breasts, lymphoma, ceruminous adenoma, brain tumors, as well as those targeting the bones.

But the thing is the tumors that start in the lungs (technically referred to as primary lung tumors), nearly 80% of them are cancerous. This simply means that if a cat has a primary lung tumor, it is highly likely that it will develop into lung cancer sooner or later.

A quick look at how lung cancer develops in cats

At its simplest, cat lung cancer begins when abnormal cells multiply and cause genetic damage over time.

This results in the formation of a lung tumor, which can either be classified as "primary lung tumors" or "secondary lung tumors." The latter is often the result of a metastatic disease when it comes to lung cancer in felines.

We will differentiate the two as we go along.

However, regardless of whether it is primary or secondary, thorough physical examination and other procedures (such as computed tomography and abdominal ultrasound) have to be done to get a definitive diagnosis.

 

Possible Causes of Lung Cancer in Cats

It is difficult to identify a singular reason why a cat has developed lung cancer. What we do know though, is that older cats and Persian cats tend to develop this cancer more frequently. And like in humans, cigarette smoke is a risk factor, too.

We've outlined some of the most possible triggers that can lead to the development of lung cancer in your pet's body below:

Age

Although there is no average age as regards the development of cancers and tumors in cats, they typically affect felines that are in their older or senior years. This is because beyond adult cats often have a weakened overall immune system health.

This is the reason why boosting your cat's immune health as early as now is essential to make him ideally resilient to disease and illness.

Genetic predisposition

If we're being honest, all cat breeds are vulnerable to cancer. But there are specific breeds that seem to be prone to this serious health concern compared to others, namely the Siamese, Bengal, and Persian.

Your pet's susceptibility to primary lung cancer will also increase if either of his parents were diagnosed with the same, too.

Underlying health conditions

While an underlying cause, such as diabetes, heart disease, or kidney issue won't directly cause the development of either tumor type or cancer of the lung in cats, they can significantly negatively affect your pet's immune response.

Again, providing your cat with a proper immune system booster can help keep these health problems in check.

Exposure to harmful chemicals

Akin to humans, cancer cells tend to get in the picture when a feline is constantly exposed to chemicals that can have a toxic effect on his lungs. These include emissions from vapes, smoke from cigarettes and cigars, as well as harsh household chemicals like oven cleaners and bleaches.

Decreased immune system health

Sure this may sound repetitive, but a poor immune system health can severely increase your cat's risk of cancer in the long run. Just to emphasize, cats whose immune systems are in tiptop shape generally have the best prognosis when it comes to tumor and cancer cases.

 

What are the Symptoms of Lung Cancer In Cats?

It’s important to know the signs of lung cancer in cats so you know when to get proper treatment and support (or perhaps palliative care) for the same. This is also crucial for the administration of the appropriate symptom management.

Here are some of the most common symptoms to watch out for in the context of feline lung tumor and cancer:

  • Difficulty breathing or sudden rapid breathing

  • Reduced exercise or unexpected exercise intolerance

  • Wheezing or coughing

  • Pleural effusion (or fluid accumulation in the lungs)

  • Poor appetite or severely decreased appetite

  • Weight loss

  • Lumps and bumps that are causing swelling in the chest cavity

While not all of these symptoms point to lung tumors in cats, you should get your cat checked out if you notice any of these symptoms! The earlier any sickness is diagnosed and treated, the better the outcomes generally are.

What's alarming, though, is that not all cats show symptoms when they have lung tumors or cancer. They may only show significant physical changes like weight loss. Technical procedures like CT scans may be required.

Keep in mind that while lung cancer is rare in cats, its effects can be extremely detrimental to your kitty's quality of life if neglected. Regular checkups with your vet are important to keep tabs on your pet’s health.

 

Conventional Procedures in Determining the Presence of Feline Lung Cancer

Several procedures are used to determine the existence of lung tumors in cats. Whether it's getting a fix on primary lung tumors or metastatic lung tumors, the following are the usual procedures administered:

Physical examination

This is perhaps the most non-invasive diagnostic method used to check for lung cancer in felines. To describe this in a very straightforward sense, it generally involves a physical exam where the chest and neighboring areas will be checked for suspicious lumps and bumps. Chest X-rays are also going to be used for further analysis.

Fine needle aspiration (FNA)

In this procedure, a fine needle is inserted into a bump or lump to extract fluid and cells. These will be subsequently tested for primary lung tumors or their secondary counterparts. It may also be resorted to in cases of lung digit syndrome. This procedure is also referred to as "fine needle biopsy." General anesthesia may or may not be used.

Complete blood count (CBC)

Blood is extracted from the affected area or areas to monitor the presence of tumor markers. This can be also performed before, during, or after a conventional treatment like radiation therapy or chemotherapy.

Chest X-ray

Also technically called "chest radiographs," chest X-rays are used to check for anomalies in the areas covered by the respiratory system, which can include tumors and cancer. It can be also used in conjunction with other procedures to check for other symptoms.

Imaging or digital means

A computed tomography (CT) scan or CT scan is utilized to generate digital internal "photographs" of the chest and other affected areas. CT scans are often performed by trained professionals using high-tech medical equipment.

 

What are Primary Lung Tumors?

Primary lung tumors are a class of tumors that originate in the lungs and will not spread to other organs when they develop or grow. This type of tumor may progress to primary lung cancer in some cats.

Are they the same as primary lung cancer?

No, primary lung cancer is the proliferation of abnormal cells. A tumor is usually indicated by neoplasms, bumps, or lumps. The recommended treatment for either health concern is also different.

Distinction from secondary lung cancer

Secondary lung cancer in cats is the result of metastatic cancer from a different part of the body that subsequently spreads to the lungs. A metastatic lung cancer may have originated from other organs like the pancreas and breasts, or perhaps the bones.

 

What are Metastatic Lung Tumors?

Metastatic lung tumors are tumors that originate from a different part of the body and then spread to the lungs. This type of tumor often results in the development or formation of multiple tumors. The recommended treatment may be entirely different from that of metastatic lung cancer.

Conventional cancer treatment usually involves procedures like radiation therapy and chemotherapy.

 

Lung Cancer In Cats: Life Expectancy

The life expectancy of lung cancer in cats depends a lot on the severity and spread of the cancer, but it is generally less than one year. Sadly, more than half of cats diagnosed with lung cancer have metastasized, meaning the tumors have spread to other parts of the body.

In the later stages, this cancer often spreads to the nearby lymph nodes and other areas of the lungs.

 

Treatment of Feline Lung Cancer

Depending on your cat’s circumstances, your vet might recommend surgery to remove the tumor and affected area. If surgery isn’t possible or if the cancer has spread, they might also recommend chemotherapy.

 

Conventional Options in Treating Lung Cancer

The most common treatment options for lung cancer in felines are as follows:

Surgical removal

As the name suggests, it involves the invasive procedure of removing the cancer through surgical means. Surgery may also be resorted to in the case of a tumor.

Radiation therapy

Radiation therapy makes use of very intense beams of light to induce cancer cells to die. Interestingly, this type of cancer treatment incorporates X-rays in its administration. Radiation therapy often has nausea, vomiting, and sudden hair loss as side effects.

Chemotherapy

This type of treatment utilizes powerful chemicals to kill off cancer. It can be used in all stages of cancer in felines. However, due to the chemicals involved, your pet will be exposed to adverse side effects like loss of appetite and extreme lethargy.
