You're having a good time with your kitty, and as you're petting them — wait, what's that?
Discovering a lump or a bump on your pet can be worrisome. You start to think of the worst — is it an infection? Cancer? The bump or lump could be from a simple bee sting or as frightening as a cancerous growth. Regardless, it is important to take immediate precautions and consult your vet.
Some lumps and bumps can be small and circular, while others can be large and irregular. Some may have a strange red color, while others may have no distinct color from the cat's skin. If the lump or bump you found on your kitty gives you sleepless nights, this blog explains everything you need to know about lumps and bumps. We will also be making special consideration on cancerous lumps on your cat.
Are Cancerous Lumps on Cats Hard or Soft?
You know how worrying it can be to find a lump on your cat's skin — cancer hits your mind. But not all lumps on pets are cancerous.
The lumps you find on your can cat are benign or malignant. However, it can be challenging to conclude with naked eyes — most lumps, malignant or benign, look similar. Your vet can tell more based on its appearance, texture, where it is on the body, and how quickly it's growing.
Cancerous lumps in cats are not always soft or hard — Some can be hard and others soft, while others also change from soft to hard with time. Cancerous lumps in the cat have one thing in common, they spread quickly in other parts of their body.
Are Lumps on My Cat Cancerous?
To determine whether the lump on your cat's skin is cancerous, your vet can perform one of the following tests:
- Fine Needle Aspiration (FNA). A fine needle is inserted into your cat's lump to suck out cells. The vet then places the cells on a slide and examines them through a microscope. If inconclusive results, your vet can send the sample to specialists for further examinations. This is the most common diagnosis of lumps and bumps.
- Impression smear. If the lumps contain discharges, your vet can rub the slide onto the tip and conduct a similar examination with an FNA.
- Lab test. If the lump discharges fluid, the fluid can be extracted and taken for more analysis in the laboratory.
- Biopsy. When the FNA examination is inconclusive, your vet can conduct a biopsy. The biopsy can either be incisional or excision. An incisional biopsy involves removing a piece of the lump, while an excision involves removing the entire lump for examination.
So, don't jump to conclusions if you find a soft or a hard lump on your cat. It would be best to have your pet evaluated for common cat diseases, and your vet can help you understand more about the lump based on its appearance and the evaluation performed.

When Should I Worry About a Lump on My Cat?
Are you worried that a large lump appeared on the cat overnight? It's understandable to be frightened. But, are cat skin lumps normal? Does my pet need to see a vet immediately?
While you should not ignore a new cat lump on the neck, in most cases, such lumps are nothing to worry about . Your local vet has probably encountered countless lumps and bumps, and they can help you determine when there is a major problem to address.
If you realize that your cat has a lump on the back near the spine or any other part of its body, the first step is to take a deep breath. Next, note the size, color, location, and any other distinct feature of the lump. Then contact your vet for more analysis.
However, seek immediate specialized treatment if you notice the following aspects of the lump:
- The lump/bump is painful to the touch or when the cat moves
- The lump is growing, charging, or spreading to other parts
- The skin area has changed color or is swollen
- Your cat was diagnosed with cancer in the past
- The lump is bleeding or discharging fluids

- Your cat has advanced in age (7 years or older). Senior cats need extra attention for better lives. When your cat enters the golden age, physical, and mental health changes can change rapidly.

Is it Normal for Cats to Have Lumps?
It's important to note that lumps and bumps are not always nasty. It's quite normal for cats to have benign lumps in their lifetime.
However, you mustn't assume every lump or bump is benign, as some can be cancerous.
Common Types of Lumps in Cats
Benign lumps and bumps cannot spread to other parts of the body. This makes most of them of little concern or threat to your cat's life. However, some can grow over time, affecting the overlying skin and causing irritation to the pet.
Some of the benign lumps and bumps in cats include:
- Abscesses. These are often caused by foreign bodies, bites, or other traumas. Abscesses develop as pus-filled lumps or pockets. They can cause discomfort and irritation to the cat but can be treated easily. In some instances, cleaning the wounds is effective.
- Cysts. Also referred to as sebaceous cysts, these are common lumps on felines. They are caused by the clogging of oil produced by the sebaceous gland. The oil gets clogged under the skin resulting in swelling and infection. On many occasions, cysts swell and burst by themselves. But some may need a vet intervention. Cysts don't present a threat to your cat's health as they rarely become tumors.
- Hives. They develop as small red bumps resulting from insect bites and allergic reactions from food and contact. Hives can be difficult to notice even when petting your cat. However, you can find small raised hair tufts or skin sensitivity.
- Lipoma. These fatty, soft, movable lumps often develop under the skin. They can occur in any part of the cat's body and vary in size from small to fairly large. Lipoma has no severe effects on your cat, but it is essential to have them checked by your vet to confirm they are not cancerous bumps.
- Cat acne. Similar to humans, cats can get acne. Most time, you may not realize when your can has acne, but if the acne becomes infected, you can notice bumps around the chin area. Washing the skin with medicated detergents to relieve irritation and any itchiness.
- Nipples. Don't be surprised! Male and female cats have nipples on their bellies. If you are unsure whether the swelling you found on your cat's belly is a nipple or a lump, try to locate the corresponding one on the other side. If still unsure, consult your vet.
- Granulomas. These lumps develop as red bumps and can have a crust. They often appear firm and aggressive. Granulomas can also develop under the skin and feels firm.
- Skin tags and warts. They are also common types that shouldn't give you sleepless nights. They rarely require medical treatment unless they bleed regularly or scratch them when grooming.
- Parasite and Stings. Does your cat go outdoors? Then, don't panic when you find a bump or a lump on the skin after an outdoor play. Bee, mosquitoes, and wasp stings can cause a bump or lump on your cat's skin. They are less harmful unless they occur on your cat's face.
- Similarly, parasites such as fleas and ticks can affect your pet's skin. When you remove the parasite, the bump can heal within a short time without any treatment.
What Does a Cancerous Lump on Cats Feel Like?
Consult your vet when you notice a large lump appearing on the cat overnight and looks worrisome. While it is not possible to tell whether the lump is cancerous, a medical examination can diagnose cancer within a short time.
Diagnosing cancerous lumps and bumps before they spread on your cat's body enhances effective treatment.
Cancerous Lumps and Bumps in Cats
While benign bumps and lumps in cats are nothing to worry about, malignant lumps can be health-threatening to your pet. This is because they can affect various parts of your cat's body, including the skin, bones, organs, and the brain.
But, no reason to panic! Regular grooming and vet checkups can help diagnose them before they spread across the body.
Some of the common types of malignant lumps and bumps include:
- Mast cell tumours. They are responsible for several tumors in dogs and cats and affect the animal's blood cells and immune system.
- Melanomas. Although less malignant in cats than in humans, melanomas emerge from pigment-producing cells that can cause pigmented growth.
- Fibrosarcomas. They often feel like lipomas but cause severely invasive tumors.
- Breast tumors. The tumors are spread throughout the body by metastasis, often affecting the lymph, other mammary glands, and organs. It is difficult to feel a mammary tumor, but can manifest as firm masses under the skin.
