Sometimes tumors can become cystic or fluid filled. In some cases we can drain these swellings but oftentimes they will refill. They may take just a day or two to refill, or months, and it is impossible to predict. If your dog is in otherwise good health I would talk to your vet about removing the growth or if they feel uncomfortable doing so, referring you to a veterinary surgeon with more experience removing large growths such as this. They may be willing to drain the swelling at your vet's office, just be warned that it can refill.

    IT is quite possible the fluid could be drained off but in many cases it will refill quickly as a cavity will be left behind. If she is otherwise well, surgical removal may still be worth considering; commonly all of one side of the mammary tissue is removed in one surgery to remove all affected tissue; both sides may be taken in a staged procedure if necessary
