My dog Misty (age 14, spayed, but very very happy fit, and very active) recently had a mammary tumor removed. I got the lab. report on
this tumor today. The cells were part benign, and part malignant. 2 types of malignancy present. I was not told which specific forms, just that there were two types.
The vet got good margins in excision, & superficial examination of inguinal lymph nodes ( position of the tumor on lower mammary gland) showed no irregularity or enlargement.
