Dog has slow-growing, balloon-like lump on belly. What is it?

Thanks for using Petco Pet Education Center, formerly Petcoach! This looks like a mammary tumor. This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have her evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

Poor Tinker! Some lipomas (fatty tumors) can become fixed, but yes general they are movable. Unfortunately, being fixed to the underlying tissue is a common characteristic of malignant tumors. Any suspicious lumps should be examined by your vet. Your vet can perform a test called a fine needle aspirate on it. To do this, your 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 recommend taking Tinker into your vet today or first thing tomorrow.

A lump in this location could be a mammary tumor. These are growths in the breast tissue. They can be benign or malignant. I always recommend surgical removal because they continue to grow, even if they are not cancerous. Another possibility would be a hernia. If this is a hernia, surgery would be recommended to repair it because organs such as intestines, bladder or uterus can become entrapped. I would recommend an evaluation by a veterinarian to determine what it is and make recommendations on how to treat it.

Hello, & thank you for using Petco Pet Education Center, formerly Petcoach. The end of the nodule seems to have an ulcerated appearance which concerns me. Definitely have your vet take a look at this. I would recommend removal & having the tissue sent for pathology for identification. It looks like a full excision should be curative. Hope this helps. Take care.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Monkey. First off, love her name! Fatty lumps can grow to be quite big over time, but it is worth getting checked out. 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 to make her an appointment. I hope this helps!
