My unspayed cat has a swollen nipple. Is it a mammary tumor?

I'm wondering if your cat is spayed or not. If your cat isn't spayed, she could have a mammary tumor. In cats, 90% of these are malignant. She does have to see a vet for this problem, as a malignant tumor could also be causing her to vomit. Please take her into a vet now. Best of luck.

Thank you for submitting your question regarding Princess. Yes, I would make an appointment for her to see her veterinarian right away. Cats, that have not been spayed, are very prone to developing mammary tumors. The majority of these tumors are unfortunately cancerous. If this appears to be the case, her veterinarian may recommend some testing or discuss surgery with you. I hope this information helps!

Unspayed dogs can be prone to mammary tumors, which causes swelling and pain. Fifty percent of these mammary tumors are malignant, so you will need to take Mocha into a vet first thing in the morning to have this examined and diagnosed. Once the cause is found, the vet can discuss treatment options with you. Best of luck.

Since the same lesion repeatedly fills with fluid, I would suspect a cyst of some sort. While this is not an emergent condition, your cat should be examined by a vet within the next week. Your vet will be able to draw a sample of fluid and cells from the lesion that can be evaluated microscopically, as this will help to determine the underlying cause. Until that time, do not express additional fluid because this can open the lesion up to infection.

It would be hard to determine what the growth is without having it examined by a vet. Infections such as abscesses often are hot to the touch, painful, swell rapidly and may ooze debris from them if they pop open. Tumors and other growths may have different rates of growth and may or may not be bothersome to your cat. It is best to bring him into your vet to have the area looked at, and it may be drained or aspirated to take a sample for sending off to the lab. If the area is an infection, it can be drained and antibiotics given to prevent its return. Until you can get to the vet it is best to not allow your cat to lick or chew at the area with the use of a T-shirt or Elizabethan (cone) collar so that bacteria or a secondary infection are not introduced.

Thank you for submitting your question regarding Mellow. I recommend showing the bumps to her veterinarian tomorrow at the check in for surgery. You can be advised if they are anything to worry about for her. Older cats will develop mammary growths, but this would be unusual in such a young kitten. It is hopefully fine, but you do need to mention it. I hope this information helps!

Hi. It appears to be a mass that is oozing near that nipple area. This could be an infection or an actual mass. We get concerned with older female pets who have masses on the mammary glands. They can get benign masses, but they can get cancer as well. I'd get her right away to have it checked and sampled asap
