Q. My chihuahua just had a mass removed with spleen, no visual sign of spread. Eating well post surgery, white covering on mass, could it be benign?
JESSICA L DESROSIERS
A. The mass would have to be sent to a lab for analysis in order to determine if the cells are benign or malignant. It would be impossible to tell if the mass was benign or not simply by looking at it. Your vet may also want to monitor your dog with X-rays or other testing over a period of months to watch for signs of spread of the mass to other body parts or in the blood.

A. Many splenic masses are benign, however the answer below is correct - the only way to know for sure is with a biopsy.
