Mast Cell Tumor

Winchester, a 9-year-old Golden Retriever, started limping and had a hard “knot” in his armpit. A week later he was in much more pain and his entire leg was swollen, so his owner took him to their family veterinarian where he was started on medication and began feeling better but test revealed that Winchester had a mast cell tumor on his left front leg and he was referred to Dr. Wirth. 

Generally, mast cell tumors are removed surgically with wide, clean margins to decrease the likelihood of it returning. In Winchester’s case, the tumor could not be removed with ample margins without amputating his leg. Dr. Wirth’s plan included a combination of chemotherapy here at WVRC along with local radiation therapy at UW-Madison, which could provide long-term control. 

Winchester did great with the chemotherapy treatments and only experienced a mild radiation burn on his leg, which is common. In fact, his owner was surprised that the treatments didn’t keep Winchester down and out. His appetite was better than ever, he was very happy, bright, energetic and livelier than before. 

Twelve weeks later, Winchester has “Kicked Cancer’s Tail” and is all healed up and playing ball again! Way to go Winchester, we look forward to seeing you at your follow up visits.
