Thanks for your prompt reply. There are a number of things these lumps could be and they may be both completely seperate things here. They could potentially be anything from sebaceous cysts or follicular cysts (which are benign) to malignant masses like soft tissue sarcomas
or mast cell tumors
The best next step here for your girl is to have both lumps checked by your local Vet. For this, a Fine Needle Aspirate (or FNA) would be taken and this could very well be all that is needed to reach a diagnosis. This is a quick and simple procedure that can typically be done without any anesthetic. A needle is inserted in to each mass, some cells are removed and smeared on slides and then a histopathologist reviews the slides to check the cells present and often he or she will be a able to give a diagnosis from there.
Depending on this initial diagnosis via FNA - further steps may need to be taken. It could be that these are benign lumps that can be left, or your Vet may suggest that they are removed, particularly if they are found to be malignant lumps.
I hope all of the above makes sense? Please let me know if you have any other questions. 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.
Best of luck with your girl and let me know how you get on if you get a chance.
