Precious has had a bump since June. Its has only grown a little, she doesnt bother it & isnt having any other problems. Does this mean its a good chance of being benign? Tne needle aspiration came back as something the vet couldnt read but it was something of the same cell & tightly packed. If there were mast cells she would have seen & knew that right? It will be removed & tested but im still so scared. Shes my best friend Also since the needle yesterday its oval shaped instead of round. Why?

Thanks for using Petco Pet Education Center, formerly Petcoach! The fact that it has been growing slowly is good though it can still be a malignant tumor and removal would be recommended if there is no evidence of cancer spread to other organs. It probably changed in size and shape as a reaction to the aspiration. Given that it is so close to her mammary glands this may be a mammary tumor. Further recommendations would be made after it is removed and the biopsy read out. Good luck and have a great day!
