Cancer Screenings for Cats

Cancer is one of the most challenging diagnoses a cat owner can hear, yet early detection can dramatically improve your feline companion's prognosis and quality of life. Unlike dogs, cats often hide signs of illness until disease progresses significantly, making regular cancer screenings an essential part of preventative veterinary care. Understanding what screenings are available and when your cat should have them can help you catch potential problems before they become life-threatening.

Why Cancer Screening Matters for Cats

Cats are notoriously stoic animals that mask discomfort and symptoms until illness reaches advanced stages. Research shows that early detection of feline cancers—such as lymphoma, squamous cell carcinoma, and mammary tumours—significantly improves treatment outcomes and survival rates. Regular screening gives your veterinarian the opportunity to identify abnormalities when intervention is most effective, potentially adding years of quality time with your beloved pet.

Common Cancers in Cats

• Lymphoma: The most common feline cancer, often affecting the gastrointestinal tract, mediastinum, or other organs
• Squamous Cell Carcinoma: Typically develops in the mouth, skin, or oesophagus
• Mammary Tumours: Most commonly seen in unspayed females
• Fibrosarcomas: Soft tissue cancers that can develop at injection sites
• Mast Cell Tumours: Skin cancers that vary widely in behaviour

Types of Cancer Screening Available

Physical Examination

Your veterinarian's hands-on examination remains the cornerstone of cancer detection. During routine checks, they assess your cat's body condition, palpate the abdomen and lymph nodes, inspect the mouth and skin, and evaluate overall health. These clinical examinations should occur at least annually, or twice yearly for senior cats aged seven and over.

Bloodwork and Biochemistry

Annual blood panels can reveal abnormalities suggesting cancer, including elevated white blood cell counts, anaemia, or organ dysfunction. Senior cats particularly benefit from comprehensive screening that includes a full blood count and biochemistry profile.

Imaging Studies

Ultrasound and radiographs help identify internal tumours or abnormalities not detectable during physical examination. Your vet may recommend imaging if they discover suspicious lumps or if bloodwork suggests problems.

Specialised Testing

Depending on findings, your cat may undergo biopsy, fine-needle aspirates, or advanced imaging such as CT scans to confirm diagnosis and stage disease accurately.

When to Start Cancer Screening

Cancer can develop at any age, but risk increases significantly after age seven. Most veterinarians recommend establishing baseline bloodwork around age five to seven, then implementing regular screening protocols. Senior cats benefit most from twice-yearly examinations and annual blood work, as early detection becomes increasingly valuable with advancing age.

What to Expect During Screening

1. Your vet conducts a thorough physical examination
2. Discussion of any behavioural or health changes you've noticed
3. Bloodwork collection if indicated
4. Imaging or additional testing if abnormalities are found
5. Clear explanation of results and next steps

Key Takeaways for Cat Owners

Cancer screening is an investment in your cat's longevity and wellbeing. Begin preventative screenings by age five, schedule annual examinations for adult cats and twice-yearly visits for seniors, keep detailed records of any health changes, and maintain open communication with your veterinarian about family history of cancer. Early detection paired with modern treatment options offers genuine hope. By remaining vigilant and proactive about your cat's health, you're giving yourself the best opportunity to catch problems early and provide the care they deserve.
