Hi, my male dog is 13, he has developed a movable lump on his left side, it is oval shaped and doesnt bother him in the slightest, he lays on it, knocks it and allows us to touch it..there have been no other apparent changes in his behaviour. Im worried about it but also worried that if it is cancerous we wont be able to afford his treatment..many thanks..
Welcome and thanks for asking your question. My name isXXXXX am a licensed veterinarian. I am happy to answer your question today. First I need to ask you a few questions so that I can be well informed and give you the best advice.

1- Where is the lumps located?
2- Is it above or below the skin?
3- How long has he had it?

There may be a slight delay between your follow ups and my replies as I type out a thorough reply for you.

1. the lump is located on his left side, above the ribcage.

2. it is below the skin.

3. i'm not sure, we didn't really notice it at first, it seemed to get bigger overnight.

Do you put him frequently in that area to feel comfortable in saying the lump came on within a day or so?

no, i didnt notice the lump at first so i dont know how long it took for it to come on, once we had noticed we decided to keep an eye on it and if there were any changes in him to then take him to the vet.

Claire, the fact the lump is movable with the skin it means it is not firmly attach to the underlying tissue which is good sign. You see, lumps that are cancerous tend to be locally invasive. It sounds like what you are describing could be a cyst or lipoma (fatty tumor) both of which are benign (not malignant). To determine the exact nature of the lump I would recommend you speak to your family veterinarian about doing an FNA (fine needle aspirate); this is a very quick test where your vet will collect a sample of the cells with a needle. Requires no anesthesia, inexpensive when compared to a biopsy and can be done within minutes during an office examination. Your vet will most likely submit sample to a lab to be evaluated under the microscope for a definitive diagnosis. The decision of benign neglect or complete surgical removal should be made based on FNA results.

My goal is to provide you with excellent service – if you feel you have gotten anything less, please reply back. I am happy to address follow-up questions. Thank you for your business and I hope to work with you again soon!
