My dog has a lump on his chest I can feel but not see. Is it a tumor?

It could be a benign mass or tumor like a lipoma, or it could be something more serious. If the lump is new, if it seems painful, or if it is very firm and fixed in place you should encourage your friend to get it checked out by a veterinarian soon.

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. There is no way of knowing what it is just based on its appearance. 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 night!

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. Typically, if a mass is not changing in size, and is soft and freely movable, most of these masses are benign and nothing to worry about. The only way to know for sure is for your veterinarian to sample some cells from the mass, either via a fine-needle aspirate, or with a larger biopsy and evaluate the cells under a microscope. Since it is small, soft, freely movable, and unchanged over the course of a year, your vet likely believes this mass is benign and feels comfortable having you monitor it at home. I hope this is helpful - best of luck with Oscar!

It depends on what you mean by "lumps." Lumps and bumps are very common in dogs and can be in the skin itself, sometimes with hair, sometimes without, or under the skin (the skin slides over the lump or you can move the lump under the skin). Lumps can be an infection like an abscess or a granuloma, or they can be a tumor. Lumps that are tumors can be benign (such as a fatty tumor) or malignant (such as a squamous cell carcinoma). The can occur literally anywhere in the body, and there is no one area o the body where they are more common. They can feel firm or soft depending on what their cause is. Most people find lumps or bumps just while petting their dog in day to day life. While its a great idea to make a point once a. month or so to run your hand over your dog to look for anything worrisome, theres no need to be too alarmed or concerned when you are just "on the lookout." If you do see or feel a lump or bump , call your vet and get him in to have it looked at. Thanks for asking Petco Pet Education Center, formerly Petcoach!

This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take her 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.

Hello, thank you for your question about Leo. The lump on Leo's side could be a variety of things, benign or malignant. Based on the symptoms you are describing one of the most likely types is a lipoma, a benign fatty tumor. These tend to be nonpainful and grow slowly in size. However, other types of masses are possible. The best way to identify the specific type of mass would be to have Leo seen by a veterinarian so that they can examine the mass and collect a small sample of cells from the mass for analysis. Once the type of mass is known further treatment options can be discussed. Although I can't say for sure it is uncommon for most types of skin cancer to lead to urinary/fecal accidents. Hope this helps, good luck!

Thanks for using Petco Pet Education Center, formerly Petcoach! Being benign vs. malignant is more based on how it looks under the microscope. It can still be benign even if it is not very movable.
