Hi, Welcome to Just Answer. I'm Chris, a small animal Vet based in the UK. I am reviewing your question and will get back to you as soon as possible
Sorry to hear that you have had this concern with your dog. It sounds like your vet performed a test known as a 'Fine Needle Aspirate' in order to try and determine what the lump is and to see if it needs to be removed. Unfortunately if the lump is quite vascular (has a good blood supply) then blood contamination can make it difficult for the pathologists to gain a diagnosis from the sample. In this situation we have three main options
1.) Repeat the Fine needle aspirate and see if a less contaminated sample can be obtained
2.) Attempt to remove the mass surgically and send it away for histopathology (analysis)
3.) Take a larger biopsy from the mass surgically under anaesthetic and then return at a later date to remove it if necessary
Unfortunately without further information we cannot determine if the mass is benign or malignant, but if removal is likely to be problematic (i.e if there is not much skin to close the wound) then I would suggest doing all we can to determine what the mass may be before resorting to a radical surgery to remove it.
I hope that makes sense?
Please let me know if you need any further help or advice.
Yes indeed there is always some risk, age itself is not necessarily a risk factor but age does bring with it the risk of underlying health problems. A blood test would be advisable to check her liver an kidneys prior to considering any anaesthetic.
Yes it may be wise to attempt to repeat the needle aspirate. However bear in mind some tumour types do not shed their cells well and cannot easily be diagnosed that way, meaning a more invasive biopsy is needed.
Thank you for your kind accept of my answer. Please let me know if you have any further questions.
