1. What is Cancer in Cats?

Approximately 6 million cats in the United States are diagnosed with cancer each year. Cancer occurs when cells grow and divide uncontrollably, leading to the formation of tumors. According to research from the Cornell Feline Health Center, early detection and appropriate treatment can significantly impact a cat’s survival and quality of life. It’s important to understand that 53 to 83% of tumors in cats are cancerous. Cancer in cats can be managed with proper care.

1.1 What Are the Types of Cancer in Cats?

Cats can develop a variety of cancers, each affecting different parts of the body. Here are some of the most common types:

Lymphoma: This is the most common type of cancer in cats, affecting white blood cells called lymphocytes. The GI tract, kidneys, and lymph nodes are commonly affected.
Mastocytoma: These tumors develop from mast cells, which are made in the bone marrow and circulate throughout the body. They most often develop in the skin or spleen.
Leiomyosarcoma: A rare but painful soft tissue cancer that affects muscles in the stomach and intestines.
Fibrosarcoma: This affects soft tissues such as muscle and connective tissue. It spreads slowly but can be locally aggressive.
Mammary Tumors: These affect the tissue surrounding a cat’s teat. They are aggressive and generally spread to nearby lymph nodes and the lungs.
Osteosarcoma: Bone cancer that affects the skeleton of cats. It is locally aggressive and painful.
Ceruminous Gland Adenocarcinoma: Develops in a cat’s sweat glands and often occurs in the ear canal.
Melanoma: Often isolated, raised masses that may bleed. They can affect many parts of the body, including the mouth, skin, and eyes.
Myeloproliferative Neoplasm: A type of blood cancer that originates from the bone marrow.
Squamous Cell Carcinoma (SCC): The most common skin tumor in cats and grows quickly.
Hemangiosarcoma: A fast-growing tumor that develops from blood vessel cells and may cause internal bleeding.
Transitional Cell Carcinoma (TCC): A tumor that grows in the bladder of cats and is locally aggressive.
Uterine Cancer: Rare in cats and typically affects middle-aged and/or older cats. Treatment involves surgical removal of the uterus (ovariohysterectomy), commonly referred to as a spay.
Ovarian Tumors: Also uncommon but prone to metastasis (spreading). Often, the ovaries are a site of metastasis from other types of cancers. Treatment involves surgical removal of the ovaries, as in the case of a spay.

Lymphoma is the most common type of cancer in cats, affecting white blood cells called lymphocytes.

1.2 What Are the Symptoms of Cancer in Cats?

Symptoms of cancer in cats can vary, but some common signs include:

Symptom	Description
Weight Loss	Unexplained and significant weight loss, despite a normal or increased appetite.
Loss of Appetite	A sudden or gradual decrease in appetite, leading to reduced food intake.
Lethargy	Persistent tiredness or lack of energy, making the cat less active and playful.
Lumps or Bumps	Any unusual growths or swellings under the skin that may be hard or soft.
Difficulty Breathing	Shortness of breath, rapid breathing, or coughing.
Vomiting or Diarrhea	Persistent or recurring episodes of vomiting or diarrhea.
Changes in Urination	Increased or decreased urination, straining to urinate, or blood in the urine.
Lameness	Difficulty walking or limping, which may indicate bone cancer or tumors in the limbs.
Non-Healing Sores	Sores or wounds that do not heal properly.
Changes in Behavior	Unusual aggression, hiding, or other behavioral changes.
Enlarged Lymph Nodes	Swollen lymph nodes, which can be felt under the skin, especially in the neck, armpits, or groin area.
Oral Tumors or Ulcers	Growths, sores, or bleeding in the mouth, which can cause difficulty eating.
Nasal Discharge or Bleeding	Persistent nasal discharge or bleeding from the nose.

If you observe any of these symptoms, consult with your veterinarian promptly for a thorough examination.

1.3 What Are the Causes of Cancer in Cats?

Many factors have been linked to cancer in cats:

Age: The risk of cancer generally increases with age, although some cancers are more common in younger cats.
Genetics: Some cats may inherit a predisposition to certain types of cancer.
Environmental Factors: Exposure to toxins like tobacco smoke and asbestos can increase the risk.
Viral Infections: Viruses like feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) can increase the risk of lymphoma and other cancers.
Sun Exposure: Prolonged exposure to UV light can increase the risk of skin cancer, particularly squamous cell carcinoma.

Prioritize annual vet appointments for young adults and biannual appointments for cats older than 8 years.

2. How Veterinarians Diagnose Cancer in Cats

Diagnosing cancer in cats involves a comprehensive approach. Your veterinarian will:

Review Medical History: Collect a detailed history of your cat’s symptoms and overall health.
Physical Examination: Perform a thorough physical exam to check for any abnormalities.
Blood and Urine Tests: Conduct blood and urine tests to assess organ function and detect any signs of cancer.
Imaging Tests:
- X-rays: To view the chest, abdomen, or limbs.
- Ultrasound: Provides real-time images of internal organs.
- Endoscopy: Involves inserting a small camera into the mouth or rectum to view the stomach or intestines.
- Computed Tomography (CT): Uses a computer to create cross-sectional images of the body with high resolution and contrast.
- Magnetic Resonance Imaging (MRI): Provides detailed images of the body without using radiation.
Sample Collection:
- Fine Needle Aspirate (FNA): Inserting a needle into the tumor and using a syringe to suction cells for examination under a microscope.
- Biopsy: Surgically removing part of the tumor for microscopic examination. Biopsies typically provide a more accurate diagnosis.

Cats that are not healthy enough for sedation or anesthesia may not be able to undergo more advanced tests, such as CT or MRI imaging, or a biopsy.

3. Treatment of Cancer in Cats

Whether your cat’s cancer is curable depends on several factors, including the cancer type, pre-existing health conditions, cancer stage, and tumor location and size. Your cat’s veterinary team will help determine the best treatment plan, which may involve:

Surgery: Commonly performed to remove tumors located near the surface of the skin or that are localized to one area.
Chemotherapy: Given by injection or orally to kill cancer cells. It is often used for cancers that have already spread.
Radiation: Radiation therapy uses targeted beams of radiation to kill cancer cells. It may be suggested for tumors that cannot be surgically removed.
Immunotherapy: Uses your cat’s immune system to fight cancer, but it is relatively new in cats.
Photodynamic Therapy: Combines light and light-sensitive substances to destroy cancerous tissue.

A combination of treatments is often suggested for cats with cancer. For example, surgery to remove the tumor, followed by chemotherapy, can help ensure all cancerous cells have been removed or destroyed.

Some cats may not be healthy enough to withstand treatment, in which case palliative care may be used to keep them comfortable. Your cat’s veterinarian may prescribe pain and anti-inflammatory medications, a special diet, fluid therapy, and blood transfusions.

3.1 What About Palliative Care?

Palliative care focuses on managing symptoms and improving the quality of life for cats with cancer. According to the American Animal Hospital Association (AAHA), palliative care is essential for ensuring comfort and dignity, regardless of the stage or type of cancer. Your veterinarian may prescribe:

Pain Medication
Anti-Inflammatory Drugs
Special Diet
Fluid Therapy
Blood Transfusions

4. Recovery and Management of Cancer in Cats

Each cat’s post-treatment recovery and timeline varies. Your veterinarian will provide instructions and expectations for your cat’s individual needs.

There are several ways you can support your cat’s recovery:

Keep them in a quiet enclosed space with fresh water, food, a bed, and litterbox nearby.
Closely monitor your cat.
Assist with your cat’s needs, such as grooming or eating.
Follow guidelines given by your cat’s veterinarian.
Prioritize follow-up appointments.

Many cats who are not candidates for treatment can still have a good quality of life. However, if a cat’s quality of life begins to decline, humane euthanasia may be recommended by the veterinarian. Your veterinarian can walk you through this option to ensure you and your cat are comfortable during the process.

Your veterinarian will help you decide what your cat may need during recovery. Below is a list of possible items:

Medications: Pain relievers, anti-inflammatories, and other medications as prescribed by your veterinarian.
Special Diet: A diet tailored to your cat’s specific needs, which may include high-protein, easily digestible foods.
Supplements: Nutritional supplements to support immune function and overall health.
Comfort Items: Soft bedding, blankets, and toys to keep your cat comfortable and entertained.
Litter Box: An easily accessible litter box, especially if your cat has mobility issues.
Water and Food Bowls: Elevated bowls can help if your cat has difficulty bending down.
Pet Carrier: For transport to and from veterinary appointments.

5. Prevention of Cancer in Cats

Although many types of cancer can’t be prevented, there are some steps you can take to reduce your cat’s overall risk.

Reduce your cat’s exposure to indoor toxins, such as asbestos and tobacco smoke.
Minimize your cat’s exposure to UV light.
Prioritize annual vet appointments for young adults and biannual appointments for cats older than 8 years.

6. Understanding the Prognosis: How Long Can a Cat Live With Cancer?

How long can a cat live with cancer? The prognosis for a cat with cancer depends on several factors, making it difficult to provide a specific answer. These factors include the type of cancer, the stage at diagnosis, the cat’s overall health, and the treatment options available. While some cats may only live a few weeks or months after diagnosis, others can live much longer, even years, with appropriate treatment and care. Early detection and intervention are crucial for improving a cat’s prognosis.

6.1 What Factors Affect a Cat’s Life Expectancy With Cancer?

Several key factors influence how long a cat can live with cancer:

Type of Cancer: Different types of cancer have varying prognoses. For example, lymphoma may respond well to chemotherapy, extending a cat’s life significantly, while aggressive cancers like hemangiosarcoma may have a poorer prognosis.
Stage of Cancer: The stage of cancer at diagnosis is critical. Early-stage cancers that are localized (haven’t spread) are generally easier to treat and have a better prognosis than advanced-stage cancers that have metastasized (spread to other parts of the body).
Location of Tumor: The location of the tumor can impact treatment options and prognosis. Tumors in easily accessible locations may be surgically removed, improving the cat’s chances of survival.
Overall Health of the Cat: A cat’s general health, age, and any pre-existing conditions play a significant role. Cats in good health are better able to tolerate aggressive treatments and may have a better prognosis.
Treatment Options and Response: The type of treatment chosen (surgery, chemotherapy, radiation, immunotherapy) and how well the cat responds to that treatment significantly impact life expectancy.
Aggressiveness of Cancer: Some cancers are more aggressive than others, meaning they grow and spread more rapidly. Aggressive cancers typically have a poorer prognosis.

6.2 How Does Cancer Type Affect Life Expectancy?

Different types of cancer in cats have varying life expectancies:

Lymphoma: With treatment, some cats with lymphoma can live for several months to over a year. The prognosis depends on the type of lymphoma and the cat’s response to chemotherapy.
Squamous Cell Carcinoma: If caught early and treated with surgery or radiation, cats with squamous cell carcinoma may live for several years. However, if the cancer has spread, the prognosis is poorer.
Mammary Tumors: The prognosis for mammary tumors depends on whether the tumor has spread to the lymph nodes or lungs. Early detection and surgical removal can improve the cat’s chances.
Osteosarcoma: This is an aggressive bone cancer, and the prognosis is generally poor. Treatment with amputation and chemotherapy may extend life expectancy, but it is often limited to several months.
Fibrosarcoma: These tumors can be locally aggressive, but with surgical removal, some cats can live for a year or more.

6.3 What Role Does Staging Play in Predicting Survival?

Staging is a critical factor in predicting survival. The stage of cancer refers to how far the cancer has spread in the body. A lower stage (e.g., Stage I or II) typically indicates that the cancer is localized and hasn’t spread, offering a better prognosis. Higher stages (e.g., Stage III or IV) mean that the cancer has spread to regional lymph nodes or distant organs, which can significantly reduce life expectancy.

Veterinarians use staging systems to determine the extent of the cancer and to guide treatment decisions. These systems often involve imaging tests, biopsies, and other diagnostic procedures.

6.4 Are There Cases of Cats Living Longer Than Expected With Cancer?

Yes, there are instances where cats live longer than expected with cancer. These cases often involve:

Early Detection: Finding the cancer early, before it has spread, allows for more effective treatment.
Aggressive Treatment: Owners who opt for aggressive treatment options, such as surgery, chemotherapy, and radiation, may see longer survival times.
Positive Response to Treatment: Some cats respond exceptionally well to treatment, leading to remission or prolonged survival.
Supportive Care: Providing excellent supportive care, including pain management, nutritional support, and a stress-free environment, can improve a cat’s quality of life and potentially extend survival.
Alternative Therapies: Some owners explore alternative therapies like acupuncture, herbal remedies, and dietary changes in conjunction with conventional treatments. While the effectiveness of these therapies varies, they can sometimes contribute to improved well-being and survival.

6.5 How Can Owners Make the Most of the Time They Have Left?

When a cat is diagnosed with cancer, owners can take several steps to make the most of the time they have left:

Focus on Quality of Life: Prioritize your cat’s comfort and well-being. Ensure they have a comfortable, stress-free environment, access to fresh water and nutritious food, and plenty of love and attention.
Pain Management: Work closely with your veterinarian to manage any pain or discomfort your cat may be experiencing.
Nutritional Support: Provide a diet that meets your cat’s nutritional needs and is easy to eat and digest.
Regular Vet Visits: Maintain regular veterinary appointments to monitor the cancer’s progression and adjust the treatment plan as needed.
Spend Quality Time: Make the most of your time together by engaging in activities your cat enjoys, such as petting, grooming, and playing.
Create Memories: Take photos and videos to document your time together and create lasting memories.
Consider Palliative Care: Palliative care focuses on providing comfort and support to cats with terminal illnesses. It can include pain management, nutritional support, and emotional support.
Prepare for End-of-Life Decisions: Discuss end-of-life decisions with your veterinarian and make a plan for when your cat’s quality of life declines significantly.
Seek Support: Connect with friends, family, or support groups to share your experiences and receive emotional support.

Prioritize annual vet appointments for young adults and biannual appointments for cats older than 8 years.
