Why Mammary Lumps in Cats Deserve Extra Attention

One thing every cat owner should know: roughly 80–90% of mammary tumours in cats turn out to be malignant, compared to around 50% in dogs, where benign tumours are actually more common. This is one of the clearest cases where "small and hasn't grown much" doesn't mean "nothing to worry about" — in cats, mammary lumps are treated as a priority for assessment and, in most cases, removal, precisely because of how often they turn out to be cancerous.

If you can feel even a small lump along your cat's mammary (belly/chest) line, particularly in an unspayed or older female cat, it's worth having it checked promptly rather than taking a wait-and-see approach.

​

What We See In Practice

In my experience, mammary tumours are something we see quite often in cats — more often than a lot of owners expect. What I usually advise is that if a client can feel even a small lump along the mammary line, it's worth having it removed rather than waiting to see what it does.

A pattern I see repeatedly is the lump being found late, simply because cats hide things so well. Unless an owner is handling their cat regularly — really running their hands over them — a small lump can go unnoticed for a long time. Often, by the time it's brought to our attention, the cat has already started interfering with it themselves — licking or scratching at it — and it can look quite dramatic and concerning by that point, which is usually what finally prompts the visit.

The advice I always give is the same regardless of size or how long it's been there: there's no such thing as "it hasn't grown, so it's probably fine." We genuinely can't tell whether a lump is benign or malignant just by looking at or feeling it — that only comes from a pathologist examining it properly. My rule of thumb is always to err on the side of having it out rather than leaving it in.

Our Cat Skin Tumour Removal Pricing

​

🟢 Small           Under 1cm         From $895

🟡 Medium      1cm – 2cm        From $1,195

🔴 Large           Over 2cm          From $1,495

​

This pricing applies to uncomplicated, superficial tumours. Tumours that look suspicious on examination — including anything consistent with a mammary tumour, mast cell tumour, fast-growing, ulcerated from self-trauma, or firmly fixed to the tissue underneath — fall outside flat-rate pricing and are quoted individually once your vet has examined your cat. Given how often feline mammary lumps turn out to be malignant, these are almost always assessed and quoted on their own merits rather than at a standard rate.

​

​

Every package includes:

✔ FREE comprehensive health check

✔ General anaesthetic

✔ IV fluids

✔ Local anaesthetic

✔ Continuous anaesthetic monitoring throughout

✔ Pain relief injection and anti-nausea medication

✔ Take-home pain relief medication

✔ Take-home antibiotics (when appropriate)

✔ Elizabethan collar

✔ Post-operative recheck consultation

​

Pre-anaesthetic blood testing and histopathology are not included in this price, as we recommend these on a case-by-case basis — particularly relevant for mammary lumps, where lab testing is often the deciding factor in what happens next.

​

Multiple lumps?

Removing more than one lump in the same anaesthetic is usually more economical than separate procedures — from $200 (small) to $300 (medium) per additional uncomplicated lump.

FAQ

Are mammary lumps in cats usually cancerous?

Far more often than in dogs — an estimated 80–90% of feline mammary tumours turn out to be malignant. This is why we generally recommend removal for any mammary lump, even a small one, rather than a wait-and-see approach.

How would I even find a lump on my cat, given how furry they are?

Regular handling is the best defence — running your hands gently over your cat's body, including along the belly and chest line, every so often. Many owners only find a lump once it's grown, become sore, or their cat has started licking or scratching at it.

Does a lump need to be growing to be a concern?

No. A lump that hasn't changed in size for a long time isn't automatically safe — we genuinely can't tell whether a lump is benign or malignant without proper testing, regardless of how long it's been stable.

What if my cat has already been licking or scratching at the lump?

This is common, and it can make a lump look far more alarming than it might otherwise — inflamed, raw, or ulcerated. It's still worth having assessed rather than waiting for it to settle down on its own, and in many cases this kind of self-trauma is a sign it's time to have it addressed.

Is anaesthesia safe for older or unwell cats?

Many senior cats, including those with health conditions, safely undergo anaesthesia. We recommend pre-anaesthetic blood testing where appropriate to check organ function and plan the safest approach for your individual cat.

What happens if the lump turns out to be more complex than expected?

If your vet finds the lump needs more than our standard flat-rate packages cover — wider margins, a mammary tumour, or a difficult location — we'll explain why and confirm pricing with you before doing anything beyond the standard procedure.
