My cat has a sensitive lump on her leg. Should I be worried?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Female | spayed | 6 lbs

My cat has a small lump on her back leg that has grown under her fur. It is solid and doesn't move around. She is an indoor cat that rarely, if at all, goes outside. She is very small and going on 10 years old. The lump doesn't seem to cause her any discomfort, but she doesn't like it being touched. Should I be worried?

Yes, it is best to be safer rather than sorry and have the lump checked over as soon as possible. It could be a cancerous lump that requires urgent treatment. Your vet can start sampling it with a needle and putting the content on a slide and take it from there.

This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Kitty to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.

My senior cat has a growing black lump on her leg. Is it serious?

Yes, this does sound like a melanoma. please take your cat to a vet ASAP as melanomas are very aggressive. Your vet may not even biopsy it for fear of spreading it, but opt to remove the tumor surgically under anesthesia. Do not wait, take her now.

My 15-year-old cat has lumps. Are they serious? When to see a vet?

Thank you for providing a picture of the lump on Beaju's back. It could simply be a wart, but there is always a chance that any lump on a senior cat could be malignant. Same for the lump on his front leg. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would take him into the vet on Monday to have these lumps examined and diagnosed so they can be treated as needed. I hope this helps!

What's this soft gray lump on my cat's leg? When to see a vet?

Hi Greg! Thank you for providing a picture of Lily's lump on her leg. From the picture, it could be a cyst, a benign tumor, or a malignant tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would take her into the vet in the next couple of days to have the lump examined and diagnosed so it can be treated as needed. Good luck, I hope this helps!

My dog has a soft lump on her leg with a hairless spot. What is it?

This lump could be a cyst, abscess, lipoma, benign tumor, or a malignant tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. Give her vet a call in the morning to make her an appointment. Best of luck.

My cat has a growing, painless leg bump. Should I worry about it?

I do recommend having it tested. It may just be something as simple as a cyst if it is fluid filled, but without being able to feel the lump it is hard to determine that. If it is a cyst and it does not bother your cat, your veterinarian may be able to drain the cyst although it can easily fill back up.

What's this solid, painless lump on my cat's leg? Is it serious?

Please take Sabbath in to have the lump examined. The most common lumps in cats are from infections but those generally are hot and painful. Cats do get masses that can be cancerous so having it examined is best. They can get some cells through a small needle and have it looked at to determine if it needs to be removed. The lump may be benign or an infection which would be nothing to be concerned about but I recommend finding out for sure what it is. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Sabbath.

My cat has a shoulder lump. Should I worry if she purrs when touched?

In a cat this young, the lump is likely to be something like a cyst or a benign tumor. Any suspicious lumps should be examined by the vet. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of its cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. Once the cause of the lump is diagnosed, the vet can discuss treatment options if needed. I'd call Baby's vet to make her an appointment to get this checked out. Best of luck.
