It’s important to remember that not every lump on your cat could be cancer. There are a lot of things that can cause cats to get lumps. They might go out exploring in the morning and come home later with a new lump on them.
If your cat has a new lump, it’s best to make an appointment with your vet to get it checked. Lumps, bumps, funny scabby bits, non-healing wounds – things that don’t belong on the skin and are refusing to go away on their own need attention. This is doubly true if they’re growing, spreading, funny colours, or weird shapes.
Not all lumps and bumps on our cats are the same. There are a few types of lump vets commonly see, including:
There are two types of tumour that could be found on your cat’s body: benign (not cancerous) or malignant (cancerous).
Lipomas are non-cancerous lumps. They are fatty tumours that can show up anywhere on your cat’s body. They are more common in older cats or cats who are overweight. These lumps are usually harmless unless they are in a place that is getting in your cat’s way. You can find out more information about managing your cat’s weight on our advice pages.
Cancerous lumps can also appear anywhere on your cat depending on the type of cancer they have. If any new lumps appear on your cat, you should take them to your vet to get checked.
There’s no way of knowing if a lump is cancer just by looking at it so your vet may need to run tests. This might include taking a cell sample from the lump (usually using a needle) which can be uncomfortable for your cat but is over very quickly! Sometimes your vet may need to take a larger sample or remove the lump entirely for further testing.
If you find a new lump on your cat, it’s best to book an appointment with your vet as soon as possible. All new lumps should be checked by your vet as they are best placed to assess what kind of lump it is and any treatment moving forward.
It’s best not to take a ‘wait and see’ approach, as some lumps will need immediate medical treatment, especially if they are infected. If your cat has a cancerous lump, delaying treatment could mean that the cancer has time to spread.
The treatment for your cat’s lumps will depend entirely on what they are and what has caused them. Some treatments can include:
