Took our 7-year old female rescue greyhound to the vets yesterday, as she has a visible lump in the inside of her knee. We noticed this about 10-14 days ago, and it has grown over this time and gone from to pink to pink with a reddish centre, its around 1 cm in dia.
Her first reaction was a mast cell tumour, but could be a cyst. You can feel under the lump so it doesn't appear to be anchored to connective tissue. We have her booked in on Friday for a needle biopsy under sedation as she is a typical greyhound - prim donna!
My question for any vets is why bother waiting 5-days for biopsy results, why not simply go for the surgical removal on Friday and send the whole thing for histopath. This way we save a week. The only thing I can come up with mild sedation for biopsy vs major anaesthesia for lump removal which may be unnecessary.
Many thanks, this is a worrying time for us.
