Can benign intestinal masses in dogs cause perforation?

It can be very difficult to determine exactly what area of the bowel is affected by a mass without invasive and expensive testing which may not be in Jake's best interests given the very poor prognosis. However some benign prostate conditions can be more treatable in entire males (if no blood changes such as elevated calcium are detected). A specialist ultrasound exam, prostatic wash or needle biopsy from the prostate can be worthwhile as if benign may respond to medical treatment in some cases

If the masses on the liver / spleen ruptured, I would expect her abdomen to be getting larger and her gums to be getting pale due to the hemorrhage. If she has black tarry stool, my concern is that the cancer is also somewhere in the GI tract. If clinically she is unchanged and doing ok, I would speak with the oncologist and see what the recommendations are in regards to this. The fact that there are cancerous changes evident on the liver and spleen, tells me that this is spreading, which is not good. However, that being said, these could be benign. I just worked on my friends dog who had a liver mass and splenic tumor in his dog. I surgically removed a liver lobe and the spleen and the dog is doing better than ever still and this was done about 6 months ago. There is no way to tell for sure whether or not these are cancerous masses until a biopsy is done or the masses are removed and sent out to the laboratory for testing. As long as Chewy is stable and doing the same, I would recommend speaking with the oncologist and see what their opinion is considering all of these changes. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Piper! The only way we can 100% know for sure a mass isn't cancerous is by either aspirating the mass with a needle or biopsying it. When a mass changes I always recommend that the animal be seen by their Vet to have it checked. The fact the mass opened up dictates the need to have it looked at and a minimum of antibiotics started. Hopefully it is just a ruptured follicular cyst that is infected. But I think you should have the mass removed and biopsied. I am afraid it will not heal well and continually leak bloody fluid. I hope this helps and I wish Piper the best!

Hi there and thank you for using Petco Pet Education Center, formerly Petcoach to address your concern. It is difficult to say for sure what these tumors are just by looking at photos. However, that being said, the light pink mass I would suspect to be benign / non-cancerous and it looks like what we call a sebaceous adenoma. The dark purple mass looks a little more suspicious for a malignant / cancerous mass. I would recommend having a veterinarian examine both to be on the safe side. The vet can insert a small needle into both masses and look at their cells under the microscope, a test called a Fine Needle Aspiration (FNA). I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns and I would be more than happy to help you further. Please remember to rate this answer as helpful or not. Thank you!

Not necessarily. It depends on the cause of the mass. Now if it’s a splenic hemangiosarcoma, the life expectancy with surgery is three months, and that’s if Bessy survives the surgery. The mass could be something like an abscess, but I can’t say for certain. You can try to give her a chance, and maybe luck will be in your favor and it’s not cancer. But if it is cancer, letting her go is the kindest option. I hope this helps.

The object in the intestine could be a benign mass or a cancerous mass. The only way to know it to get a biopsy of the mass. It is concerning that he has fluid outside of his lungs and your vet may be able to get a sample of the fluid and submit to a lab for testing. If there are any cancerous cells in the fluid than you would have a probable diagnosis without putting your dog through surgery for a biopsy. Hope our vet can diagnose the problem soon.

Thanks for using Petco Pet Education Center, formerly Petcoach! Overall, from what I'm reading and seeing, I have a low level of concern about Mukwa. This lesion does not look typical of a mast cell tumor (though that type of cancer does not always follow the "rules"). In general, non-cancerous things do not become cancerous with time - though there are exceptions. Occasional vomiting is not necessarily something I equate with Mast Cell Tumors, but does warrant a chat with your vet to see if it's something worth looking into. More concerning signs to me would be decreased appetite, weight loss, or lethargy. Best of luck to you and Mukwa!
