Cancer in Pets

A cancer diagnosis — or even the worry of one — is one of the hardest things a pet owner can face. We want to be straight with you about what this page is, and what it isn’t.

This is not a cancer-treatment page. Diagnosing and treating cancer is the work of your veterinarian and, where available, a veterinary oncologist. If your pet has been diagnosed, or you’ve noticed something that worries you, the most useful thing we can tell you is to speak to them — promptly, and as your first step.

What we will not claim

The internet is full of confident promises that a particular diet, food or supplement can shrink, starve, fight or cure cancer in pets. We won’t make those claims, because the evidence doesn’t support them, and because a pet with cancer deserves real veterinary care — not a feeding experiment in place of it. We’d rather lose your click than risk your pet’s treatment being delayed by something we wrote.

Where food does fit in

A pet going through cancer treatment still needs to eat, stay hydrated and stay comfortable — and good nutrition matters to that. But the right plan depends entirely on your pet’s specific cancer, its treatment, and how it’s coping day to day. That makes it a conversation for your vet or oncology team, who can tailor it to your pet — not something to take from a general web page. If you feed, or want to feed, a fresh diet, tell your vet, and let them fold it into the plan.

Signs worth a vet visit

Many of these have causes other than cancer — but all of them are worth having your vet check, the sooner the better:

• Lumps or swellings that don’t go away or that grow
• Sores that won’t heal
• Unexplained weight loss or loss of appetite
• Bleeding or discharge, or persistent vomiting or diarrhoea
• A persistent offensive smell (mouth, nose or rear)
• Difficulty eating, swallowing, breathing, urinating or defecating
• Lasting lameness, low energy or reluctance to exercise

If you’re seeing any of these, please book a veterinary appointment rather than waiting — early assessment gives your pet the best options.
